Chapter 1 Router Overview
1.1 Introduction
3Com 6000 Routers are next generation high-performance edge routers that 3Com
Corporation solely developed. They provide high forwarding performance and a broad service
range. The Router 6000 supports flexible interface cards (FICs), hot swappable fan modules
and power supply units (PSUs) in 1+1 redundancy. Along with the NE Series Routers, the
Router 6000 provides complete network solutions for service providers and enterprises.
The following are the major features of the Router 6000.
I. Abundant FIC options
Abundant FICs are available with the Router 6000 allowing great flexibility and investment
protection.
II. Ethernet access
The electrical and fiber (multi-mode and single-mode) FE FICs available with the Router
6000 support PPPoE and PPPoEoA that can offer authentication, authorization, and
accounting (AAA) services for Ethernet access, hence satisfying the requirements of
government offices and enterprises in broadband access.
III. ATM and DSL
Digital subscriber line (DSL) is a simple but highly efficient broadband technology that
achieves great data transmission capacity over existing copper wiring by using the digital
code modulation technology. Installed with an ADSL or G.HSDSL card, the Router 6000
can connect the medium-to-small-sized enterprises to the digital subscriber line access
multiplexer (DSLAM) equipment through a public switched telephone network (PSTN) and
then to the Internet.
Asynchronous transfer mode (ATM) transmits, multiplexes, and switches information in
cells. The Router 6000 can be installed with these ATM cards: 25 Mbps, 155 Mbps, E3,
and T3. The cards support ATM adaption layer type 5 (AAL5) and offer traffic services such
as constant bit rate (CBR), variable bit rate (VBR) and unspecified bit rate (UBR). They are
well-suited to transfer large packets and provide high-speed data services. A
medium-and-small-sized enterprise can use them to connect its network to an ATM
network.
IV. MPLS
Multiprotocol label switching (MPLS), a combination of IP and ATM technologies, replaces
the IP header with a short and length-fixed label as traffic identifier, based on each routers

forwarding decision. It thus provides faster forwarding speed, gets support from IP routed
protocols and control protocols, and accommodates to emerging applications. MPLS VPN
is a VPN technology that uses label switched paths (LSPs) to interconnect private
networks. As a LSP is virtually a tunnel across the public network, MPLS has an intrinsic
advantage in terms of VPN implementation. The 3Com 6000 Routers usually act as label
edge routers (LERs) to connect an MPLS domain with a non-MPLS domain or connect
MPLS domains of different service providers, implementing service classification, label
distribution, encapsulation, and multi-label peel-off.
V. Data security and reliability
The following are the data security and reliability features that the Router 6000 supports:
z
NAT. Besides some basic functions, NAT can limit concurrent connections to a
single user, and thus alleviate negative impacts caused by malicious resource
occupation without affecting the normal network applications. In addition, NAT of
the Router 6000 also provides the application layer gateway (ALG) function
specific to FTP and ICMP.
z
z
z
Authentication protocols such as PAP, CHAP, data RADIUS, and VoIP RADIUS.
Packet filter and firewall, which fend off external attacks.
VPN (including GRE, L2TP, and MPLS) and the technologies of IPSec and IKE.
They can ensure security of private networks in an Internet environment.
Backup center and virtual router redundancy protocol (VRRP). By providing a
backup scheme in case of communication line or device failures, they enhance
robustness and reliability of networks. Backup center also supports backup load
sharing.
z
z
Hot swappable fans, interface cards, and PSUs to ensure high reliability.
VI. Online software upgrading
You are allowed to upgrade application and Boot ROM programs, and add new features
and functions on line as needed.
VII. Abundant fault isolation methods
z
The monitoring of the states of system configurations, system service channels,
and system resources is available, as well as fault indication via console and
network management host. In addition, logging function is provided for recording
and outputting the abnormal information.
z

1.4.2 PSU
I. Functions
The power supply system of the Router 6000 can work in either single-power or dual-power
mode. In dual-power mode, the two PSUs (DC-input or AC-input) function in redundancy or
load sharing mode. That means, when a PSU fails or its power supply is disconnected, another
PSU can still work and supply all the power required by the system.
Both AC-input PSU and DC-input PSU are available with the Router 6000. The PSUs supply
350W power and provide overcurrent and overvoltage protection.
You can connect a PSU to the backplane by inserting it from the rear of the router chassis. It is
hot swappable and its switchover does not affect the ongoing system operation.
Note:
When installing your router in a communications equipment room, ensure that the AC
power distribution cabinet can provide a lightning protection box or arrester against
the current of 20 KA and above.

1.4.3 FAN module
I. Functions
The 3Com Router 6040 is configured with six fans; the 3Com Router 6080 is configured with
eight fans. These fans are working in pairs and the two fans in each pair are working in
redundancy. When all these fans are working normally, the operating temperature of the
system can be maintained between 0 and 55oC (32 to 131oF). As the failure of a fan does not
affect the operation of other fans, the normal operating temperature of the system can
maintain.
The routing speed of the fans is adjusted by the fan controller on the main control board and
between 50% and 100% depending on the system temperature. When the system
temperature rises above the high-temperature threshold set by the fan controller, the fans are
rotating at full speed (100%); when the system temperature drops below the low-temperature

Preparing for Installation
Chapter 2 Preparing for Installation
2.1 General Site Requirements
The Router 6000 must be used indoors. To guarantee normal operation and longevity of your
device, its installation site should meet the requirements described in this chapter.
2.1.1 Temperature and Humidity
The equipment room must maintain proper humidity to prevent poor insulation, electricity
creepage and corrosion accompanying high humidity, or washer contraction and
electrostatic discharge accompanying low humidity. In dry environments where the relative
humidity is very low, electrostatic discharge (ESD) is more likely causing the
complementary metal-oxide-semiconductor (CMOS) circuitry to fail.
A proper temperature condition must also be maintained to prevent premature material
aging and degraded reliability accompanying high temperature conditions.
The following table lists the temperature and humidity requirements.
Table 2-1 Temperature/humidity requirements in the equipment room
Temperature
Relative humidity
0oC to 40oC (32oF to 104oF)
5% to 90%
2.1.2 Cleanness
Dust is hazardous to the operating safety of your device. Dust buildup on the chassis may
result in static absorption, causing poor contact of metal components or points. When indoor
humidity is extremely low, this is more likely to happen to shorten the useful life of the device
and cause communication failures.
The equipment room must be free of explosion hazards and the electrical and magnetic
conductible dust as well. The following table lists the limits on dust particles:

contact with the elements on it.
2.1.4 Electromagnetic Compatibility
All interference sources, from the outside or from the inside of the router/application system,
adversely affect the router in the conduction patterns of capacitance coupling, inductance
coupling, electromagnetic wave radiation, and common impedance (including grounding
system) coupling. To prevent the interference, do the following:
z
z
Take effective measures against interference from the power grid.
Use an earthing system or lightning protection grounding different from that for
the power supply equipment and keep them as far as possible.
Keep the router far away from strong power wireless launchers, radar launchers
and high frequency and high-current equipment.

Starting and Configuring the Router
Figure 3-8 Ethernet cable
Ethernet cables fit into the following two categories:
z
Straight-through cable, at both ends of which, the wires are crimped in the RJ-45
connectors in the same sequence. The cable connects different types of devices,
such as a terminal device (PC for example) or router to a Hub or LAN switch. The
network cables shipped with the router are standard cables.
z
Crossover cable, at both ends of which, the wires are crimped in the RJ-45
connectors in different sequences. The cable connects the same type of devices,
such as PC to PC or PC to router. You can make crossover cables by yourself as
needed.
Note:
In preparing network cables, shielded cables are preferred for electromagnetic
compatibility sake.
2) Fiber-optic Ethernet interface cable
For the 10/100/1000M Ethernet interfaces on the RPU2, select single mode or
multi-mode optical fibers depending on the type of the installed 1000Base-FX SFPs.
As the interfaces that these SFP modules provide use LC-type fiber-optic connectors,
you must use fibers with LC-type connectors for them. All these SFPs are hot
swappable.
Note:
SFPs are optional. They are provided only when ordered.
III. Connecting the Ethernet cable
Note:
The fiber-optic and electrical connections that a 10/100/1000 Mbps Ethernet interface
provides cannot operate at the same time. By default, if both connections are present,
the system considers the electrical interface as the operating interface.

no link is present; check the line for the cause.
1) Connect the fiber-optic Ethernet interface cable
Caution:
In connecting optical fibers, observe the following:
z
z
z
Do not over-bend the fiber. Its curvature radius must be greater than 10 cm (3.9 in.).
Ensure that the Tx and Rx ends are correctly connected.
Ensure that the fiber ends are clean.
Warning:
Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which
are connected with lasers. To protect your eyes against radiation harm, never stare
into an open fiber-optic port.
Follow these steps to connect a 10/100/1000 Mbps fiber-optic interface on the RPU2:
Step 1: Use two fibers to connect the Rx and Tx ends of the interface to another device: Rx to
Tx, and Tx to Rx.
Step 2: Power on the router and read the LINK LED of the interface: ON means the Rx link is
present. OFF means no Rx link is present; check the line for the cause.
3.9 Connecting the Router to a WAN
Many types of WAN interfaces are available with the Router 6000 and the one provided by the
main control boards is an AUX interface. The following subsections describe how to connect it.

II. Drilling holes
Use a percussion drill with Φ16 bit to drill holes for bolting the anchor strips.
When drilling holes, hold the drill handle firmly with both hands, keeping the bit perpendicular
to the floor to prevent damages to the floor or tilted holes.
All the holes must have the same depth in the range 52 mm to 60 mm (2.0 in. to 2.4 in.). Clean
the holes before measuring their net depth. After drilling a hole, use a dust collector to clean
the dust.
The bit is difficult to position on the floor that is hard and smooth. In this case, punch a small
hole on the marks for the mounting holes before drilling.
Note that the precision of marking and drilling is essential to hardware installation. Low
precision can cause many problems during installation.
Caution:
The depth of drilling is between 52 mm and 60 mm (2.0 in. to 2.4 in.). Otherwise, you
will be unable to install or fasten the expansion bolts.
III. Installing expansion bolts
Prior to installation, clean dust inside and outside the holes with a dust collector and then
measure the spacing of holes. If errors are not acceptable, you must measure and drill again.
Follow these steps to install an expansion bolt:
1) Take down the expansion tube and expansion nut, and insert the alignment rib
on the expansion nut into the alignment groove of expansion tube.
2) Put them into a hole vertically.
3) Punch the expansion tube with rubber hammer until the expansion tube is
completely buried in the floor.
