•
•
•
Online insertion and removal (OIR)—Allows you to add, replace, or remove the modular port
adapter without interrupting the system.
Downloadable software—Allows you to load new images into flash memory remotely, without
having to physically access the router, for fast, reliable upgrades.
Network management using integrated SNMP agent—Allows you to remotely manage the router.
Cisco uBR7100 series routers support CiscoWorks and CiscoView network management software.
–
CiscoWorks—Lets you monitor complex internetworks that use Cisco routing devices and helps
you plan, troubleshoot, and analyze your network. CiscoWorks uses the Simple Network
Management Protocol (SNMP) to monitor and control any SNMP device on the network.
–
CiscoView—A graphical SNMP-based device management tool that provides powerful
real-time views of your networked Cisco devices. These views deliver a continuously updated
physical picture of device configuration and performance conditions, with simultaneous views
available for multiple device sessions. CiscoView runs from a centralized network management
site from which you can review, reconfigure, and monitor essential device data from a simple
GUI (that displays information such as dynamic status reports, performance statistics, and
network inquiries) without having to physically check connections for each device, module, or
port at every different or remote location.
Cisco uBR7100 Series Routers Physical Description
Each model includes the following physical features:
•
Cable interface—One downstream and either one or four upstreams, depending on the model of the
router. The cable interface supports the DOCSIS 6 MHz, North American channel plan or the
EuroDOCSIS 8 MHz PAL and SECAM channel plan, depending on the router model.
•

Cisco uBR7100 Series Routers Physical Description
Figure 1-3 shows the front panel for all models of the Cisco uBR7100 series routers.
Figure 1-3 Cisco uBR7100 Series Front Panel
Cisco uBR7100
SERIES
All Cisco uBR7100 series routers have one power supply with one AC-input power receptacle. A power
cable connects the AC-input power supply to the site AC power source. The router’s main power switch
is located next to the AC-input power receptacle. Separate power cords are available, depending on the
country of operation.
On the side of each chassis are two chassis ground receptacles—choose the most convenient set for a
chassis ground connection for a two-hole grounding lug, and the other set can provide a mounting
location for the cable management bracket. On the back of the chassis, there is a receptacle for
electrostatic discharge (ESD) equipment.
Four internal fans draw cooling air into the chassis (back to front) and across internal components to
maintain an acceptable operating temperature. There are four environmental sensors for monitoring the
cooling air as it leaves the chassis. For more information on environmental monitoring, see the
Caution
To ensure the proper flow of cooling air across the internal components, a port adapter must be installed
in the port adapter slot. If no port adapter is installed, install a blank port adapter (the product number
is MAS-7100-PABLANK=). Slot 5 has a blank face plate. For proper airflow, make sure that a blank
faceplate is always installed in slot 5. (The product number is SM-BLANK=).
The modular port adapter slides into the chassis slot and connects directly to the router; there are no
internal cables to connect.
The port adapter, fixed cable interface, and fixed LAN interface connect to two peripheral component
interconnect (PCI) buses on the router’s backplane that provide a path to packet I/O memory and the
system processor. For more information, see the “Peripheral Component Interconnect Buses” section on
Cisco uBR7100 series routers can be installed on a tabletop or in an equipment rack. Rubber feet for
tabletop installation are included in the accessory kit that shipped with your router.
A rack-mount and cable-management kit is also standard equipment included with all Cisco uBR7100
series routers when they are shipped from the factory. The kit provides the hardware needed to mount
the router in a standard 19-inch, four-post or telco-type equipment rack. The rack-mount kit also
provides the hardware necessary to manage the interface cables attached to the router.
Note
Hardware to install the Cisco uBR7100 series in a 23-inch or 24-inch rack can also be ordered separately
(the order number is ACS-7100-RMK=).

Chapter 1 Product Overview
Fixed Interface Units
Instructions for installing the router on a tabletop, installing the router in an equipment rack, and
attaching the cable-management bracket are given in Chapter 3, “Installing Cisco uBR7100 Series
Fixed Interface Units
The Cisco uBR7100 series universal broadband router contains the following fixed interfaces:
•
•
Ethernet/Fast Ethernet LAN Interface
The Cisco uBR7100 series contains a fixed LAN Ethernet/Fast Ethernet autosensing interface with two
separately routable 100BASE-TX ports. Both ports support full-duplex and half-duplex operation, and
automatically determine whether the attached network is a 10-Mbps 10BASE-T Ethernet or a 100-Mbps,
100BASE-TX Fast Ethernet network. Each port uses an RJ-45 connector with Category 5 unshielded
twisted-pair (UTP) wiring.
RF Cable Interface
The Cisco uBR7100 series router includes a fixed cable interface card that provides one downstream port
and from one to four upstream ports, depending on the model.
On the Cisco uBR7111 and Cisco uBR7114 routers, the cable interface supports the North American
DOCSIS channel plan, with a 6 MHz National Television Systems Committee (NTSC) channel width,
with a 5 to 42 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency
range with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data
rates.
On the Cisco uBR7111E and Cisco uBR7114E routers, the cable interface supports the EuroDOCSIS
channel plan, with an 8 MHz pulse amplitude modulation (PAM) and SECAM channel width, with a
5 to 65 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency range
with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data rates.
Two downstream connectors are provided:
•
DS0 RF—Outputs the downstream after it has been processed by the router’s integrated upconverter,
thereby creating an RF signal suitable for connection to a combiner and transmission on the coaxial
cable network.
•
DS0—Outputs the downstream as an IF signal, requiring an external upconverter to process the
signal for output on the coaxial cable network.
Note
On the Cisco uBR7111E and Cisco uBR7114E routers, the DS0 connector is automatically muted when
the DS0 RF port is enabled.

Chassis Slot and Logical Interface Numbering
In Cisco uBR7100 series routers, the slot number is the location in the chassis where the interface resides
and the port number is the physical port associated with that slot. Cisco uBR7100 series router slots are
numbered 0 through 5. Interfaces in the Cisco IOS software are identified by a type, slot number, and
port number. The number of physical ports depends on the type of modular port adapter or fixed
interface. For example, Fast Ethernet 0/1 indicates port 1 on the fixed LAN interface in slot 0.
Slots in the Cisco uBR7100 series are numbered as follows:
•
•
•
Slot 0—Fixed LAN (Fast Ethernet) interface
Slot 1—Fixed RF interface
Slot 3—Modular port adapter
Note
Slots 2, 4, and 5 are not used on the Cisco uBR7100 series router.
Figure 1-5 illustrates the slot placement on Cisco uBR7114 and Cisco uBR7114E routers. The
placement on the Cisco uBR7111 and Cisco uBR7111E routers is identical.

MAC Addresses
The Media Access Control (MAC) or hardware address is a standardized data-link layer address that is
required for certain network interface types. These addresses are not used by other devices in the
network; they are specific and unique to each port. The router uses a specific method to assign and
control the MAC addresses of its port adapter.
All LAN interfaces (ports) require unique MAC addresses. Typically, the MAC address of an interface
is stored on a memory component that resides directly on the interface circuitry; however, the online
insertion and removal (OIR) feature requires a different method. For a description of OIR, see the
The OIR feature allows you to remove a port adapter and replace it with another identically configured
one. If the new port adapter matches the port adapter you removed, the system immediately brings it
online.

Chapter 1 Product Overview
Functional Overview
To allow OIR, an address allocator with unique MAC addresses is stored in an EEPROM on the router.
Each address is reserved for a specific port and slot in the router regardless of whether a port adapter
resides in that slot.
The MAC addresses for port adapters are assigned to slot 3 in Cisco uBR7100 series routers, not to a
particular port adapter. Assigning MAC addresses to the slot and not to the port adapter allows you to
remove a port adapter and insert the port adapter into other routers without causing the MAC addresses
to move around the network or to be assigned to multiple devices.
Note
Storing the MAC addresses for every slot in one central location means the addresses stay with the
memory device on which they are stored.
Online Insertion and Removal
The modular port adapter installed in Cisco uBR7100 series routers supports OIR. This function allows
you to install and replace a port adapter while the router is operating; you do not need to notify the
software or shut down the system power. This provides a method that is seamless to end users on the
network, maintains all routing information, and preserves sessions.
The following is a functional description of OIR for background information only; for specific
procedures for installing and replacing a port adapter in a Cisco uBR7100 series router, see the
configuration note that ships with each port adapter.
Each port adapter has a bus connector that connects it to the router. Each connector has a set of tiered
pins in three lengths that send specific signals to the system as they make contact with the port adapter.
The system assesses the signals it receives and the order in which it receives them to determine if a port
adapter is being removed or inserted into the router. From these signals, the system determines whether
to reinitialize a new interface or shut down a removed interface. For example, when you insert a port
adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last.
The system recognizes the signals and the sequence in which it receives them.
When you remove or insert a port adapter in a Cisco uBR7100 series router, the port adapter pins send
signals to notify the system, which then performs as follows:
1. Rapidly scans the system for configuration changes.
2. Initializes all newly inserted port adapters, noting any removed interfaces and placing them in the
administratively shutdown state.
3. Brings all previously configured interfaces on the port adapter back to the state they were in when
they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as
if they were present (but not configured) at boot time. If a similar port adapter type is reinserted into
a slot, its ports are configured and brought online up to the port count of the original port adapter.
Peripheral Component Interconnect Buses
All interfaces connect to two Peripheral Component Interconnect (PCI) buses on the router that provide
a path to packet I/O memory and the network processor. Slots 1 and 3 use PCI bus 0, and slot 0 uses
PCI bus 1. The maximum recommended bandwidth points on each PCI bus is 600 points.
Note
Slots 2, 4, and 5 are not used in the Cisco uBR7100 series routers.

Note
For instructions for removing and replacing memory components on the network processor card, such
as the SDRAM DIMMs, refer to Memory Replacement Instructions for the Network Processing Engine
or Network Services Engine and Input/Output Controller at the following URL:
The network processor card consists of the following components:
•
•
Reduced Instruction Set Computing (RISC) microprocessor running at 175 MHz
Two system controllers—Provide processor access to two separate banks of SDRAM and permit
devices on both PCI buses to access either SDRAM bank. This means that devices on different PCI
buses can access different SDRAM banks simultaneously.
•
Upgradable memory modules—SDRAM system memory defaults to 128 MB and can be upgraded
to either 192 MB or 256 MB. (SDRAM packet memory is fixed at 64 MB.) SDRAM memory stores
packets received or sent from network interfaces, routing tables, and network accounting
applications. The two independent SDRAM memory arrays allow concurrent access by interfaces
and the processor. For information about accessing the SDRAM memory modules, refer to the
Note
The network processor card contains two SDRAM slots for user-configurable system memory, DIMM 1
and DIMM 2. The amount of memory installed in slot DIMM 1 must be greater than or equal to the
memory installed in slot DIMM 2. Slot DIMM 2 is zero for the default memory configuration of
128 MB. Slot DIMM 0 is used only for packet memory and is fixed at 64 MB in the factory.
•
Cache memory—Cisco uBR7100 series routers have two levels of cache: a primary cache that is
internal to the microprocessor and a secondary, 2-MB (fixed) external cache that provides additional
high-speed storage for data and instructions.

Chapter 2 Preparing for Installation
Safety Guidelines
Electrostatic Discharge Prevention
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs
when electronic components are improperly handled and can result in complete or intermittent failures.
Figure 2-1 illustrates how to attach an electrostatic discharge wrist strap.
Always follow ESD-prevention procedures when you remove and replace components. Ensure that the
chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it
makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to
safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and
cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of
the chassis.
Caution
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohms (Mohm).

Chassis Lifting Guidelines
A fully configured Cisco uBR7100 series router weighs approximately 32 pounds (14.5 kg). The chassis
is not intended to be moved frequently. Before you install the router, ensure that your site is properly
prepared so you can avoid having to move the chassis later to accommodate power sources and network
connections.
Whenever you lift the chassis or any heavy object, follow these guidelines:
•
•
•
•
Always disconnect all external cables before lifting or moving the chassis.
Ensure that your footing is solid, and balance the weight of the object between your feet.
Lift the chassis slowly; never move suddenly or twist your body as you lift.
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
•
Lift the chassis from the bottom; grasp the underside of the chassis exterior with both hands.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
Site Requirement Guidelines
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be
accessed only through the use of a special tool, lock and key, or other means of security.
Statement 1017
The environmental monitoring functionality in the router protects the system and components from
potential damage from overvoltage and overtemperature conditions. To ensure that normal operation and
avoid unnecessary maintenance, plan your site configuration and prepare your site before installation.
After installation, make sure the site maintains an ambient temperature of 32°F through 104°F (0°C
through 40°C), and keep the area around the chassis as free from dust as is practical.
Planning a proper location for the router and the layout of your equipment rack or wiring closet is
essential for successful system operation. Equipment placed too close together or inadequately
ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible
by poor equipment placement can make system maintenance difficult. Following are precautions that can
help avoid problems during installation and ongoing operation.
Follow these general precautions when planning your equipment locations and connections:
•
•
Plan for access to both front and rear panels of the chassis.
Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical
equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating
temperatures without adequate ventilation.
•
Use the show environment command regularly to check the internal system status. The
environmental monitor continually checks the interior chassis environment; it provides warnings for
high temperature and maximum and minimum voltages and creates reports on any occurrences. If
warning messages are displayed, take immediate action to identify the cause and correct the
problem.
•
•
We recommend keeping the router off the floor and out of any area that tends to collect dust.
Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge
can cause immediate or intermittent equipment failure.
•
Ensure that the port adapter (or the blank port adapter) is in place and secure for proper cooling. The
fans direct cooling air throughout the chassis interior; a loose component or empty slot can redirect
the air flow away from active components.
Rack-Mounting Guidelines
The rack-mounting hardware included with router is suitable for standard 19-inch equipment racks and
telco-type racks; brackets for 23- and 24-inch racks are available separately. To easily access the
interface cables while the router is installed in a rack make certain that you have access to the rear of the
router.
Before using a particular rack, check for obstructions (such as a power strip) that could impair
rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the power
strip before installing the router in the rack, and then replace it after the chassis is installed. As an
alternative, you can mount the router on an equipment shelf, provided that the rack dimensions allow
you to secure the router to the shelf and the overall configuration permits safe installation and access.
However, we recommend rack-mounting the router.

Site Requirement Guidelines
Figure 2-2 shows the chassis outer dimensions and required footprint for the Cisco uBR7114 universal
broadband router. The dimensions for the other models of Cisco uBR7100 series routers are identical.
Figure 2-2 Cisco uBR7114 Router Footprint and Outer Dimensions
Chassis width
17.5 in. (44.45 cm)
To use the rack-mounting hardware provided with the router, consider the following guidelines:
•
To mount the router between two posts or rails using the brackets, the inner clearance (the width
between the inner sides of the two posts or rails) must be at least 17 inches (43.18 cm).
•
•
The height of the chassis is 3.5 inches (8.89 cm).
When mounting the router in four-post or telco-type racks, be sure to use all the screws and the
brackets provided to secure the chassis to the rack posts.
•
If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and
designing a customized shelf. We recommend that you use the rack-mount kit designed for
Cisco uBR7100 series routers.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
When planning your rack installation, consider the following guidelines:
Install the router in an open rack whenever possible. If installation in an enclosed rack is
•
unavoidable, ensure that the rack has adequate ventilation.
An enclosed rack should have louvered sides and a fan to provide cooling air, because heat generated
by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment
above.
Caution
To prevent chassis overheating, never install the router in an enclosed rack or room that is not properly
ventilated or air conditioned.
•
•
•
•
Ensure that the rack is not congested, because each unit generates heat. Maintain a minimum
clearance of 3 inches (7.62 cm) on the back and front of the chassis for the cooling air inlet and
exhaust ports, respectively.
Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the
chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be
found by experimenting with different configurations.
When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the
equipment by itself, if possible. Power off other equipment in the rack to allow the unit under test a
maximum of cooling air and clean power.
Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it
back near a wall or cabinet for normal operation and pull it out for maintenance (installing or
removing a port adapter or connecting cables). Otherwise, allow 19 inches (48.3 cm) of clearance
to remove the port adapter.
•
•
Install the chassis and external devices to which it will connect in a contiguous stack.
Always install heavier equipment in the lower half of a rack to maintain a low center of gravity and
prevent the rack from falling over.
•
•
If you use telco-type racks, be sure that the rack is bolted to the floor and secured, because in these
types of installations only one end of the chassis mounts to the two rack posts with the brackets.
Ensure that the weight of the chassis does not make the rack unstable.
Provide an adequate chassis ground (earth) connection for your router chassis.
Note
We strongly recommend that you provide a chassis ground connection. (See “Attaching the System
Ground Connection” section on page 3-5 for instructions.)
In addition to the preceding guidelines, review the precautions for avoiding overtemperature conditions
Cisco uBR7100 series chassis in a rack, see the instructions given in “Rack-Mounting the Chassis”
Temperature and Humidity Requirements
Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are
those within which Cisco uBR7100 series routers continue to operate; however, a measurement that is
approaching the minimum or maximum of a range indicates a potential problem. You can maintain
normal operation by anticipating and correcting environmental anomalies before they approach a

Power Connection Guidelines
Follow these precautions and recommendations when planning power connections to a Cisco uBR7100
series router:
•
Check the power at your site before installation and periodically after installation to ensure that you
are receiving clean power. Install a power conditioner if necessary.
•
The AC power supply includes the following features:
–
–
Autoselects either 110V or 220V operation.
All units include a 6-foot (1.8-meter) electrical power cord that is appropriate for the country
of operation.
Warning
Warning
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that
the protective device is rated not greater than: 15A minimum, 60VDC. Statement 1005
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection
authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
•
•
Use a grounded AC power outlet and install proper grounding to avoid damage from lightning and
power surges.
The AC-input power supply operates on input voltage and frequency within the ranges of 100 to
240 VRMS and 50/60 Hz without the need for operator adjustments. This power supply also
incorporates an active power factor corrector that minimizes the unwanted generation of line current
harmonics that can cause overload of site electrical distribution systems.
Note
We recommend an uninterruptible power source to protect against power failures at your
site. We recommend powering a Cisco uBR7100 series router from a 15A receptacle at the
power source.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
Note
The Cisco uBR7100 series router installation must comply with all applicable codes and is approved for
use with copper conductors only. If installing the router in a central office environment that requires
Telcordia grounding, the ground bond fastening hardware should be of compatible material and preclude
loosening, deterioration, and electrochemical corrosion of hardware and joined material. Attachment of
the chassis ground to a central office or other interior ground system should be made with a minimum
6-AWG, copper ground conductor.
To satisfy Telcordia grounding requirements, the chassis provides two threaded chassis grounding
receptacles, located on the sides near the rear of the chassis, which are intended to be bonded directly to
the central offices or other interior ground system. The chassis ground requires 3.5 mm screws, which
attaching the system ground.
Plant Wiring Guidelines
Following are guidelines for setting up the plant wiring and cabling at your site. When planning the
location of the new system, consider the distance limitations for signaling, EMC, and connector
compatibility, as described in the following sections.
Interference Considerations
When wires are run for any significant distance in an electromagnetic field, interference can occur
between the field and the signals on the wires. This fact has two implications for the construction of plant
wiring:
•
•
Bad wiring practice can result in radio interference emanating from the plant wiring.
Strong electromagnetic interference (EMI), especially when it is caused by lightning or radio
transmitters, can destroy the signal drivers and receivers in the router, and can even create an
electrical hazard by conducting power surges through lines and into equipment. (Review the safety
Note
To predict and remedy strong EMI, you may also need to consult experts in radio frequency interference
(RFI).
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the
plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a
high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
If wires exceed recommended distances, or if wires pass between buildings, give special consideration
to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other
high-energy phenomena can easily couple enough energy into unshielded conductors to destroy
electronic devices. If you have had problems of this sort in the past, you may want to consult experts in
electrical surge suppression and shielding.

Chapter 2 Preparing for Installation
Site Requirement Guidelines
Distance Limitations and Interface Specifications
The size of your networks and the distances between connections depend on the type of signal, the signal
speed, and the transmission media (the type of cabling used to transmit the signals). For example,
standard coaxial cable has a greater channel capacity than twisted-pair cabling. The distance and rate
limits in the following descriptions are the IEEE recommended maximum speeds and distances for
signaling; however, you can usually get good results at speeds and distances far greater than these. For
example, the recommended maximum rate for V.35 is 2 Mbps, but it is commonly used at 4 Mbps
without any problems. If you understand the electrical problems that might arise and can compensate for
them, you should get good results with rates and distances greater than those shown here; however, do
so at your own risk.
Note
We recommend that you do not exceed specified transmission rate and distance limits.
When preparing your site for network connections to a Cisco uBR7100 series router, you must consider
a number of factors related to each type of interface:
•
The type of cabling required for each type (fiber, thick or thin coaxial, foil-twisted pair [FTP], or
unshielded twisted-pair [UTP] cabling)
•
•
•
Distance limitations for each signal type
The specific cables you need to connect each interface
Any additional interface equipment you need, such as transceivers, hubs, switches, modems,
channel service units (CSUs), or data service units (DSUs)
•
Cable pinouts if you plan to build your cables
Note
The specific interface information you need is contained in the documentation that is shipped with each
port adapter.
Before installing a Cisco uBR7100 series router, have all additional external equipment and cables on
hand. For ordering information, contact a customer service representative.
Ethernet Connections
There are two 10BASE-T/100BASE-TX Fast Ethernet ports on the rear panel of the router. Both ports
use unshielded twisted-pair (UTP) cable. We recommend Category 5 UTP cable. The maximum segment
distance is 328 feet (100 meters). UTP cables look like the cables used for ordinary telephones; however,
UTP cables meet certain electrical standards that telephone cables do not. Cables are not included.
Port Adapter WAN Connections
Cisco uBR7100 series routers support a number of port adapters that provide different WAN connection
ports on the rear panel of the router. For more information on the cables used with the WAN ports, see
the documentation that accompanies the port adapter, as well as Appendix C, “Cable Specifications,”

Warning
Warning
This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260.
Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The
telecommunications lines must be disconnected 1) before unplugging the main power connector or 2)
while the housing is open, or both. Statement 1043
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first. Statement 1026
Console and Auxiliary Port Considerations
Cisco uBR7100 series routers include an asynchronous serial console port and an auxiliary port. The
console and auxiliary ports provide access to the access server either locally (with a console terminal)
or remotely (with a modem). This section discusses important cabling information to consider before
connecting a console terminal (such as PC running terminal emulation software) to the console port or
connecting a modem to the auxiliary port.
The main difference between the console and auxiliary ports is that the auxiliary port supports hardware
flow control using RTS/CTS (Request To Send/Clear To Send) signaling, and the console port does not.
Flow control paces the transmission of data between a sending device and a receiving device, ensuring
that the receiving device can absorb the data sent to it before the sending device sends more.
When the buffers on the receiving device are full, a message is sent to the sending device to suspend
transmission until the data in the buffers has been processed. Because the auxiliary port supports flow
control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals
transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console
terminals.
For detailed information about installing a console terminal and connecting devices to the auxiliary port,
pinouts, see Appendix C, “Cable Specifications,”
Console Port Connections
Cisco uBR7100 series routers include an EIA/TIA-232 asynchronous serial console port (RJ-45).
Depending on the cable and the adapter used, this port will appear as a data terminal equipment (DTE)
or data communications equipment (DCE) device at the end of the cable. Your router arrives with cables
and adapters to connect a console terminal (an ASCII terminal or PC running terminal emulation
software) to the console port.
To connect a PC running terminal emulation software to the console port, use the RJ-45 rollover cable
with the female RJ-45-to-DB-9 adapter (labeled TERMINAL). The default parameters for the console
port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The console port does not support hardware
flow control.

Chapter 4 System Startup
Starting the System
Starting the System
After installing the router and connecting cables, start the router as follows:
Step 1
At the back of the router, place the power switch on the power supply in the ON (|) position. The green
power (PWR) LED on the router comes on.
Step 2
Step 3
Listen for the fans; you should immediately hear them operating.
During the boot process, observe the system LEDs. The LEDs on the fixed interfaces and the modular
port adapter go on and off in irregular sequence. Some may go on, go out, and go on again for a short
time.
Step 4
Observe the initialization process. When the system boot is complete (a few seconds), the network
processor begins to initialize the interfaces. During this initialization, the LEDs on each port behave
differently (most flash on and off).
The enabled LED on each interface goes on when initialization is completed, and the console screen
displays a system banner similar to the following:
Restricted Rights Legend

170 West Tasman Drive
San Jose, California 95134-1706
Step 5
When you start up the router for the first time, the system automatically enters the setup command
facility, which determines which interfaces are installed and prompts you for configuration information
for each one. On the console terminal, after the system displays the system banner and hardware
configuration, you see the following System Configuration Dialog prompt:
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
You have the following options:
•
•
Enter yes to proceed with the setup facility to configure the router’s interfaces
Enter no to exit the setup procedure, and instead proceed to use command line interface (CLI)
configuration commands to configure the global (system-wide) and interface-specific parameters.
Note
You do not have to configure the interfaces immediately; however, you cannot enable the
interfaces or connect them to any networks until you have configured them.
If the system does not complete each of the steps in the startup procedure, proceed to Chapter 5,
“Troubleshooting the Installation,” for troubleshooting recommendations and procedures.

Troubleshooting the Installation
Your Cisco uBR7100 series router went through extensive testing before leaving the factory. However,
if you encounter problems starting the router, use the information in this chapter to help isolate the cause
of the problems. This chapter contains the following sections:
•
•
•
•
The procedures in this chapter assume that you are troubleshooting the initial system startup, and that
your router is in the original factory configuration. If you have removed or replaced components or
changed any default settings, the recommendations in this chapter might not apply. Make sure to review
the safety warnings listed in the publication that accompanied your Cisco uBR7100 series router before
using the troubleshooting procedures in this chapter.
Troubleshooting Overview
This section describes the troubleshooting methods used in this chapter and describes how
Cisco uBR7100 series routers are divided into subsystems for more efficient problem solving.
Figure 5-2 shows the general troubleshooting strategy described in this chapter. Refer to this chart, as
necessary, to follow the steps to isolate problems to a specific subsystem; then resolve the problem if
possible.
Before You Call for Technical Assistance
If you are unable to easily solve the problem, contact a customer service representative for assistance
and further instructions. Provide the representative with the following information:
•
•
•
•
•
•
Date you received the router
Chassis serial number
Type of software and release number
Brief description of the problem you are having

Troubleshooting Overview
Locating the Serial Number on Your Router
The serial number label is located on the input/output (I/O) side, lower-right corner of the chassis.
The serial number format is: 3 letters, 4 numbers, and 4 characters (combination of letters and numbers)
Figure 5-1 Serial Number Location
Problem Solving Using a Subsystems Approach
The key to solving problems with the system is isolating the problem to a specific subsystem. The first
step in solving startup problems is to compare what the system is doing to what it should be doing.
Because a startup problem is usually caused by a single component, it is more efficient to first isolate
the problem to a subsystem rather than to troubleshoot each component in the system. For these
troubleshooting procedures, consider the following subsystems:
•
•
Power subsystem—Includes the power supply and the external power cable.
Processor subsystem—Includes the network processing card, the modular port adapter, the service
module, and the fixed RF ports. The system memory and management functions reside on the
network processing card, and the enabled LED on each port indicates if the port is initialized. A port
adapter that is partially installed in the router can cause the system to hang and crash.
•
Cooling subsystem—Includes the fans.
The following sections help you isolate a problem to one of these subsystems and direct you to the
appropriate troubleshooting section.
Identifying Startup Problems
Startup problems are commonly due to the source power or to a port adapter that is dislodged from the
router. Although an overtemperature condition is unlikely at initial startup, the environmental
monitoring functions are included in this chapter because they also monitor internal voltages.
When you start up the router for the first time, you should observe the startup sequence described in the
“Starting the System” section on page 4-2, which contains a more detailed description of the normal
startup sequence.
LEDs indicate all system states in the startup sequence. By checking the state of the LEDs, you can
determine when and where the system failed in the startup sequence. Use the following descriptions to
isolate the problem to a subsystem, and then proceed to the appropriate sections to try to resolve the

The power LED (PWR) comes on immediately and indicates that the router is receiving power.
This LED comes on during a successful router boot and remains on during normal operation of
the router.
If this LED remains off when you start the router, either there is a problem with the power
supply (it is damaged or not connected correctly), or the network processing card is not
connected properly. Proceed to the “Troubleshooting the Power Subsystem” section on

–
The system ready LED (SYS RDY) comes on after the power LED and indicates that the
network processor card is enabled for operation by the system; however, it does not mean that
the Fast Ethernet port is functional or enabled. This LED comes on during a successful router
boot and remains on during normal operation of the router.
If this LED remains off when you start the router, it is probably a problem with the main
processor card. Contact your service representative for technical assistance.
Each enabled LED for the cable interface (EN, DS0 RF, DS0, U0, U1, U2, and U3) comes on
initially at power-on and then turns off. The LED then comes on again and remains on when the
corresponding port is enabled and configured for operations.
If an enabled LED fails to come on at initial power-on, or if the LED fails to come on and remain
on after the port is enabled and configured, proceed to the “Troubleshooting the Port Adapter
The slot 0 and slot 1 LEDs only come on when the PCMCIA card slot is being accessed by the
system. These LEDs remain off during normal operation of the router and do not indicate startup
problems.
•
The initial system banner should be displayed on the console screen.
If it is not displayed, see the “Connecting the Console Port and Auxiliary Port” section on page 3-10
to verify that the terminal is set up correctly and that it is properly connected to the router’s console
port.
Troubleshooting the Power Subsystem
Check the following to help isolate a problem with the power subsystem:
Is the power LED (PWR) on?
If yes, the power source is good, and the power supply is functional.
If no, make sure that the power cable is connected at both ends.
•
–
–
–
If the power LED remains off, and the power switch is set correctly, suspect the power source
or the power cable. Turn the switch off, connect the power cable to another power source, if
available, and turn the switch back on. If the LED comes on, the problem is the first power
source.
–
–
If the power LED fails to come on after you connect the power supply to a new power source,
replace the power cord, and turn the switch back on. If the LED comes on, return the first power
cable for replacement.
If the LED still fails to come on when the power supply is connected to a different power source
with a new power cable, the power supply is probably faulty. Contact a service representative
for further instructions.
Troubleshooting the Processor Subsystem
The processor subsystem comprises the network processing card and the ports. The system can operate
without a port adapter installed as long as none are in partial contact with the connector pins. A port
adapter that is partially connected to the router sends incomplete signals to the processor, which faults
the Peripheral Component Interconnect (PCI) bus and causes the system to hang. Therefore, first ensure

that the system software has initialized successfully. If not, remove the port adapter and restart the
system. If the system then boots, reinsert the port adapter card and, if necessary, troubleshoot the port
adapter.
Troubleshooting the Network Processor Card
The procedures in this section assume that the router is in the original factory configuration, and that you
have not made changes to your configuration file.
If the system ready LED (SYS RDY) does not come on as expected (see the “When you start up the
on page 5-3), check the following items to help isolate the problem:
•
Do all of the LEDs remain off when the system power switch is turned on?
–
If the LEDs stay off, first see the “Troubleshooting the Power Subsystem” section on page 5-4
fans and the power supply are functioning properly.
–
If the power supply and fans appear operational but the system ready or enable LEDs are off,
suspect that an improperly connected port adapter has hung the system. Reinsert the port
adapter, tighten all captive installation screws, and then restart the system.
•
Is the system ready LED on?
–
–
If yes, the system software has initialized successfully, and the system is operational.
If the system ready LED remains off, the system detected a processor hardware failure. (This
LED should be on in normal operation.) Contact a service representative for instructions.
Troubleshooting the Port Adapter and Fixed RF Ports
Check the following to help isolate a problem with a port adapter or fixed RF port:
•
Are all enabled LEDs on?
If yes, the system is operational.
•
Are any enabled LEDs off?
–
If the enabled LED on a port adapter is off, first verify that the port adapter has been enabled
and configured for operations. The enabled LED remains off when a port adapter has not been
configured and enabled.
–
If the port has been enabled but its corresponding enabled LED is still off, suspect that the
adapter has pulled away from the router. Reseat the adapter in its slot. (You do not have to turn
off the system power when removing or replacing port adapters.) After the system reinitializes
the interfaces, the enabled LED on the adapter should come on.
–
If the enabled LED remains off after the above checks, it is likely that the system has detected
a processor hardware failure. Contact a service representative for instructions.

Troubleshooting the Cooling Subsystem
Check the following to help isolate a problem with the cooling system:
•
When you start up the system, do the fans start operating?
To determine if the fans are operating, listen for them. In noisy environments, place your hand on
the front of the chassis to feel for air being pushed out of the vents. If necessary, pop off the front
bezel to expose the fans and verify that they are operating correctly.
–
–
If yes, the power to the fans is good.
If no, there is a problem with the fan or power. (See the “Troubleshooting the Power Subsystem”
•
The following messages, if displayed, indicate that the system has detected a critical
overtemperature condition or out-of-tolerance power inside the chassis:
Queued messages:

00:00:19:%ENVM-2-ENVCRIT:chassis outlet 2 measured at 30C/86F
Although an overtemperature condition is unlikely at initial startup, ensure that heated exhaust air from
other equipment is not entering the router’s inlet vent and that there is sufficient clearance around the
sides of the chassis to allow cooling air to flow.
The above message could also indicate a faulty component or temperature sensor. Use the show
environment or show environment table command to display the internal chassis environment.
If you experience trouble with the startup that is not resolved with these procedures, manually power off
the router and contact a service representative for assistance and further instructions.

Maintenance
This chapter describes basic maintenance for the Cisco uBR7100 series router. The chapter contains the
following sections:
•
•
•
•
Online Insertion and Removal
The port adapter in the Cisco uBR7100 series router supports online insertion and removal (OIR). This
function allows you to install and replace the port adapter while the universal broadband router is
operating. In most instances, you do not need to shut down system power.
The following is a functional description of OIR; for specific procedures to install, configure, or replace
a port adapter, refer to the appropriate port adapter documentation at the following URL:
The port adapter has a bus connector that connects it to the universal broadband router’s midplane. Each
midplane connector has a set of tiered pins in three lengths. The pins send specific signals to the system
as they make contact with the port adapter. The system assesses the signals it receives and the order in
which it receives them to determine if a board is being removed or inserted into the midplane. From these
signals, the system determines whether to reinitialize a new interface or shut down a removed interface.
For example, when inserting a port adapter, the longest pins make contact with the port adapter first, and
the shortest pins make contact last. The system recognizes the signals and the sequence in which it
receives them.
When you remove or insert a port adapter in a Cisco uBR7100 series router, the midplane pins send
signals to notify the system, which then performs as follows:
1. Rapidly scans the midplane for configuration changes.
2. Initializes the newly inserted port adapter, noting any removed interfaces and placing them in the
administratively shutdown state.
3. Brings all previously configured interfaces on the port adapter back to the state they were in when
they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as
if they were present (but not configured) at boot time. If a similar port adapter is reinserted into a
slot, its ports are configured and brought online up to the port count of the original port adapter.

Chapter 6 Maintenance
Environmental Monitoring and Reporting Functions
You can remove and replace a port adapter with the same type of component without interrupting the
system. To replace a port adapter with a different type of port adapter (for example, replacing a HSSI
adapter with an ATM adapter), you must to copy your startup configuration to your running
configuration on the Cisco uBR7100 series router to enable the interfaces on the port adapter.
Environmental Monitoring and Reporting Functions
Environmental monitoring and reporting functions are controlled by the network processor and allow
you to maintain normal system operation by identifying and resolving adverse conditions that might
disrupt operation.
The environmental monitoring functions constantly monitor the internal chassis air temperature and
power supply voltages and currents. The power supply monitors its own voltage and temperature and
shuts itself down if it detects a critical condition within the power supply. The reporting functions
periodically log the values of measured parameters so that you can retrieve them for analysis later, and
the reporting functions display warnings on the console if any of the monitored parameters exceed
defined thresholds.
The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent
overheating inside the chassis; we recommend at least 3 inches (7.6 cm) of clearance. Temperature
sensors in the router monitor the internal air temperature and send warning messages when the internal
air temperature exceeds the specified threshold.
Environmental Monitoring
The environmental monitoring functions use four sensors to monitor the temperature of the cooling air
as it moves through the chassis.
If the air temperature exceeds a defined threshold, the router displays warning messages on the console
terminal. The system stores the present parameter measurements for both temperature and power voltage
in NVRAM so you can retrieve them later.
In addition, the power supply monitors the internal power supply temperature and voltages. A power
supply is either within tolerance (normal) or out of tolerance (critical). If the internal power supply
temperature or voltage reaches a critical level, the power supply shuts down without any interaction with
the system processor.
The environmental monitoring functions use the following levels of status conditions to monitor the
system:
•
•
Normal—All monitored parameters are within normal tolerances.
Warning—The system has exceeded a specified threshold. The system continues to operate, but
operator action is recommended to bring the system back to a normal state.
•
Critical—An out-of-tolerance temperature or voltage condition exists. The system continues to
operate; however, immediate operator action is required.
Table 6-1 lists the typical temperature thresholds for each network processor type, and Table 6-2 lists the
power thresholds for the normal, warning, and critical (power supply-monitored) levels.

Displaying Environmental Status Reports
Cisco uBR7100 series routers display warning messages on the console if chassis interface-monitored
parameters exceed a desired threshold. You can also retrieve and display environmental status reports
with the show environment, show environment all, show environment last, and show environment
table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief
description of each of these commands follows.
Caution
To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature
conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate
clearance around the sides of the chassis so that cooling air can flow through the chassis interior
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of other device.
The show environment command displays the current environmental status of the system. The report

Formatting a Flash Memory Card
The flash memory card that shipped with your router contains the Cisco IOS software image you need
to boot your router. In some cases, you might need to insert a new flash memory card and copy images
or backup configuration files onto it. Before you can use a new flash memory card, you must format it.
(Use only Type II PCMCIA flash memory cards provided by Cisco.)
Tip
Caution
Note
To avoid potential problems when inserting spare flash memory cards in your Cisco uBR7100 series
router, we recommend that you reformat all your flash memory cards during your regularly scheduled
service times.
The following formatting procedure erases all information on the flash memory card. To prevent the loss
of important data that might be stored on a flash memory card, proceed carefully. If you want to save the
data on a flash memory card, copy the data to a server before you format the card.
The following procedure assumes that you have already booted your router.
To format a new flash memory card:
Step 1
Step 2
Using the procedure described in the “Inserting a Flash Memory Card” section on page 6-5, insert the
flash memory card into slot 0. (If slot 0 is not available, use slot 1.)
To format the flash memory card, use the format disk0: (or format disk1:) command as follows:
Router# format disk0:
All sectors will be erased, proceed? [confirm]
Enter volume id (up to 30 characters): MyNewCard
Formatting sector 1
Format device disk0 completed
Router#
The system counts down the sectors as they are formatted. For example, a 48-MB flash memory card
contains 384 sectors, and the display counts backwards from 384 to 1.
When the format routine reaches sector 1, the new flash memory card is formatted and ready to use.

Flash Memory Card Usage
Copying a Bootable Image onto a Flash Memory Card
After you have formatted a new flash memory card, you can copy a bootable image onto it. To copy an
image, use the following procedure, which assumes the following:
•
You have an I/O controller with a good image in the onboard flash memory single in-line memory
module (SIMM) so you can start the router.
•
The bootable image you want to copy to the flash memory card exists on a Trivial File Transfer
Protocol (TFTP) server to which you have access (meaning you know its name and have connectivity
to it), and at least one interface is available over which you can access this server.
Note
To ensure access to a TFTP server, you must configure at least one network interface on your
router. For instructions on using this procedure, refer to the Cisco uBR7100 Series Software
•
You know the filename of the image you want to copy onto the flash memory card.
To copy a bootable file (called new.image in the following examples) onto the flash memory card:
Step 1
Step 2
Boot the Cisco uBR7100 series router and allow it to initialize.
Insert an unformatted flash memory card and format it using the procedure in the “Formatting a Flash
Note
If you have already formatted a flash memory card, you can use it to copy files. However, you
cannot boot from a flash memory card that was formatted on another type of system. To use the
card as a boot source, you must first reformat it on the router. To avoid potential problems when
inserting flash memory cards in your router, we recommend reformatting all your flash memory
cards during your regularly scheduled service times. The “Formatting a Flash Memory Card”
section on page 6-8 contains instructions that explain how to reformat a flash memory card.
Step 3
Copy the new image (new.image) to the flash memory card and make this image the default boot image.
Then reboot the router using the following series of commands:
Router> enable
Password: <password>
Router# copy tftp:new.image disk0:new.image

Note
In this example, the exclamation points (!!!) appear as the file is downloaded, and the “C”
characters signify calculation of the checksum, which is a verification that the file has been
correctly downloaded to the flash memory card.
When the system reloads, it boots the new.image file from the flash memory card.
Copying Bootable Images Between Flash Memory Cards
As future releases of Cisco IOS images become available, you will receive these images either as a file
booted from a network server, a file on floppy disk, or a file on a flash memory card.
The following scenario describes how to use a newly released image on a flash memory card in a system
that has an older image on a flash memory card in slot 0 and a default boot image in the onboard flash
memory SIMM.
For this scenario, the filenames are as follows:
•
•
•
The new image on the new flash memory card is new.image.
The old image on the flash memory card in slot 0 (which is addressed as disk0:) is old.image.
The bootable image in onboard flash memory is boot.image.
You will copy the new image from the new flash memory card onto the flash memory card that contains
the old image.
Note
The scenario assumes that the new image will fit on the flash memory card in slot 0, alongside the old
image. If there is not enough available space, use the delete command to delete files from the flash
memory card to make sufficient room for the new image; however, do not delete the image.old file. Then
use the squeeze command to remove these deleted files from the flash memory card. If, after you have
deleted files and used the squeeze command, the two files cannot coexist on the flash memory card in
slot 0, remove this card (place it in an antistatic bag and store it in a safe place), then insert the new flash
slot0:new.image command to designate the file new.image as the default boot image.
Step 1
Step 2
Boot the Cisco uBR7100 series universal broadband router. By default, the file boot.image is used.
Enable the router as follows:
Router> enable
Password: <password>
Router#
Step 3
Insert the new flash memory card into slot 1.

Upgrading the SDRAM Memory Modules
Step 4
Use the following command to copy the file new.image in slot 1 to the flash memory card in slot 0, only
if there is enough memory space for the two images to coexist. If there is not enough memory space,
Router# copy disk1:new.image disk0:new.image
Note
You can also enter the preceding command as copy disk1:new.image disk0:.
Step 5
Use the following series of commands to designate the file new.image (which is on the flash memory
card in slot 0) as the default boot image:
Router# configure terminal
Router(config)# no boot system
Router(config)# boot system flash disk0:new.image
Router(config)# ^z
Router# copy running-config startup-config
Router# reload
When the system reloads, it boots the file new.image from the flash memory card in slot 0.
Upgrading the SDRAM Memory Modules
The Cisco uBR7100 series router has upgradable memory modules on the network processing card
located inside the router. To access these modules, you must remove the top cover of the chassis. Review
the safety information before starting this procedure.
Note
SDRAM system memory defaults to 128 MB and can be upgraded to either 192 MB or 256 MB.
(SDRAM packet memory is fixed at 64 MB.)

Integrated Upconverter Specifications
The integrated upconverter that is installed in the Cisco uBR7100 series chassis meets all DOCSIS and
EuroDOCSIS specifications. The upconverter outputs an RF signal and operates in the frequency range
of 55 to 858 MHz (band center). The output range is +50 to +63 dBmV at 64 and 256 QAM; the output
can go down to +45 dBmV but with degraded power accuracy.
Note
Note
The integrated upconverter output is available on the downstream port labeled DS0 RF. The downstream
labeled DS0 outputs an IF signal that must be put through an external upconverter before use.
On the Cisco uBR7111E and Cisco uBR7114E routers, the DS0 connector is automatically muted when
the DS0 RF port is enabled.

Cable Specifications
This appendix contains cable and cable pinout information for the Cisco uBR7100 series universal
broadband routers.
•
•
•
Note
This appendix specifies pinouts only for the pins used. Pins not listed in the tables are not connected.
Coaxial Cables
The coaxial cable used to connect the Cisco uBR7100 series universal broadband routers at the headend
should be very high-quality cable.
We recommend that you use a headend-grade coaxial cable or a quad-shield coaxial cable to connect the
cable modem cards to the hybrid fiber-coaxial (HFC) network. The center conductor must be straight
and extend 1/8 inch (3.2 mm) beyond the end of the connector, and the connector should be securely
crimped to the cable. The following headend cables are recommended:
•
•
•
59-series cable (preferred)—20 AWG (0.032 inch/0.81 mm diameter) silver plated, copper-clad,
steel center conductor; bonded foil inner shield; 95 percent braid second shield; nonbonded foil third
shield; 95 percent braid fourth shield.
59-series quad shield—20 AWG (0.032 inch/0.81 mm diameter) copper-clad steel center conductor;
bonded foil inner shield; 53 percent braid second shield; nonbonded foil third shield; 34–35 percent
braid fourth shield.
6-series quad shield—18 AWG (0.0359 inch/0.91 mm diameter) copper-clad steel center conductor;
bonded foil inner shield; 60 percent braid second shield; nonbonded foil third shield; 40–42 percent
braid fourth shield.
Note
Any of the three of the coaxial cables listed can be used to connect a Cisco cable interface card to the
HFC network; however, the consistent use of 59-series cable is preferred. If you connect a 59-series
cable to a cable interface card that was previously connected using 6-series cable, the difference in the
center connector diameter might cause intermittent connectivity loss.

Appendix C Cable Specifications
Console and Auxiliary Port Cables and Pinouts
If you use different types of coaxial cable, the following problems can appear:
•
Damage to Cisco uBR7100 series cable interface card connectors—Cable interface card connectors
are designed for 59-series or 6-series cable and connectors. Larger cables can damage the
connectors.
•
Poor return loss—High-quality cable and correct connectors help to ensure an optimal return loss of
16 dB or more.
Caution
Poorly shielded coaxial cable may result in undesired signal leakage (egress), interference from
over-the-air signals (ingress), or crosstalk between cables in close physical proximity.
Console and Auxiliary Port Cables and Pinouts
The router arrives with a console and auxiliary cable kit, which contains the cable and adapters you need
to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to the
router. The console and auxiliary cable kit includes:
•
•
•
RJ-45-to-RJ-45 rollover cable
RJ-45-to-DB-9 female data terminal equipment (DTE) adapter labeled TERMINAL
RJ-45-to-DB-25 male data communications equipment (DCE) adapter labeled MODEM

Identifying an RJ-45 Rollover Cable
You can identify a rollover cable by holding the two ends of the cable next to each other, with the tab at
the back. The wire connected to the pin on the outside of the lefthand plug should be the same color as

The colored wires at one connector are in the reverse order at the other connector (reverses pins 1 and 8,
2 and 7, 3 and 6, 4 and 5, 5 and 4, 6 and 3, 7 and 2, 8 and 1).
The wires of the straight-through cable are in the same sequence at both ends of the cable.
Note
If your cable was purchased from Cisco Systems, pin 8 is white.
Console Port Cables and Pinouts
Use the RJ-45-to-RJ-45 rollover cable and RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL) to
connect the console port to a PC running terminal emulation software. Table C-1 lists the signals and
pinouts for the asynchronous serial console port, the RJ-45-to-RJ-45 rollover cable, and the

Fast Ethernet Port Cables and Pinouts
The 10BASE-T/100BASE-TX Fast Ethernet ports support IEEE 802.3 and IEEE 802.3u specifications
for 10-Mbps and 100-Mbps transmission over unshielded twisted-pair (UTP) cables. Each Fast Ethernet
port on the router has an RJ-45 connector to attach to Category 3 or Category 5 UTP cables.
•
•
•
•
Use a Category 3 UTP crossover cable when connecting 10BASE-T port to a hub.
Use a Category 3 UTP straight-through cable when connecting to a PC or other Ethernet device.
Use a Category 5 UTP crossover cable when connecting 100BASE-TX to a hub.
Use a Category 5 UTP straight-through cable when connecting to a PC or other Ethernet device.
Note
Cisco Systems does not supply Category 3 or Category 5 UTP RJ-45 cables; these cables are available
commercially.
Identifying an RJ-45 Crossover Cable
You can identify a crossover cable by comparing the two modular ends of the cable. Hold the cables
side-by-side with the tab at the back. The first (far left) colored wire (pin 1) at one end of the cable is
the third colored wire (pin 3) at the other end of the cable. The second colored wire (pin 2) at one end
of the cable is the sixth colored wire (pin 6) at the other end of the cable. Pin 1 wire is white.

Frequency Allocation Tables
This appendix provides information on broadcast and cable television NTSC and PAL/SECAM
standards and frequencies used around the world.
There are three standards for transmitting video. They are defined by the method of encoding color onto
a monochrome signal. The methods are defined as:
•
•
•
NTSC—National Television System Committee
NTSC is the current standard used for analog television in the United States and elsewhere. NTSC
supports color television transmission in a 6-MHz channel bandwidth and has 525 interlaced scan
lines. Two fields are interlaced to make one frame with a frame rate of 29.97 frames per second and
a field rate of 59.94 fields per second. A fraction (approximately 8 percent) of the available
bandwidth is used for signal synchronization between the transmitter and the receiver, giving an
effective resolution of 640x480. The aspect ratio, or ratio of picture width to picture height, is 4:3.
PAL—Phase Alternating Line
PAL is a composite color system similar to NTSC. In PAL, however, the color difference signals
alternate phase at the horizontal line rate. PAL video consists of a 625-line frame, a frame rate of 25
Hz, and a field rate of 50 Hz. As with NTSC, approximately 8 percent of the available bandwidth is
used for synchronization yielding an effective resolution of 768x576. The aspect ratio is 4:3. The
PAL standard and its variants are used primarily in Europe, Asia, Africa, Australia, Brazil, and
Argentina.
SECAM—SEquential Couleur Avec Memoire
SECAM is a color television broadcasting system using 625 picture lines and a 50-hertz (Hz) field
rate, in which the two color-difference signals are transmitted sequentially instead of
simultaneously.

PAL/SECAM Cable Television Channels and Relative
Frequencies
Table D-6 provides information on the Phase Alternating Line (PAL) and SEquential Couleur Avec
Memoire (SECAM) frequency map for standard 7- and 8-MHz channel bands in Europe.
The FCS (reference subaltern frequency) for color integration is different for different countries. Also,
the channel and frequency designations are different for different countries. For a summary of the ITU
designations for PAL and SECAM systems and Recommendation ITU-R BT.470.6 standards, refer to
help determine frequency allocations for specific countries. Table D-6 is a frequency allocation table for
PAL B and G locations. Also note that some countries use different schemes for VHF and UHF.
More information can be found at the websites listed on page E-1.
Note
The downstream frequency plan includes all center frequencies between 112 and 858 MHz on 250-kHz
increments. It is up to the operator to decide which frequencies to use to meet national and network
requirements

it. Site log entries might include the following:
•
Installation progress—Make a copy of the Installation Checklist and insert it into the site log. Make
entries on the Installation Checklist as each procedure is completed.
•
Upgrades and removal/replacement procedures—Use the site log as a record of system maintenance
and expansion history. Each time a procedure is performed on the system, update the site log to
reflect the following:
–
