Important Information
Note
Note
The Cisco XR 12000 Series Routers must have a full set of switch fabric cards installed to support the
requirements of the Ethernet line cards. See the appropriate Cisco 12000 Series Router installation
guide for information about the switch fabric and other related requirements.
Because the 10-Port 1-Gigabit Ethernet, 1-Port 10-Gigabit Ethernet, and Modular Gigabit Ethernet line
cards require a card cage slot that is 1.8 inches (4.5 centimeters) wide, you can use these line cards in
only the Cisco 12416 Router, Cisco 12410 Router, Cisco 12406 Router, Cisco 12404 Router, Cisco
12816 Router, and Cisco 12810 Router.
Cisco IOS Software Release and Hardware Revision Requirements
The Ethernet line cards have certain Cisco IOS software requirements. Also, to ensure compatibility with
the software, your Ethernet line card should have a specific hardware revision number. The number is
printed on a label affixed to the component side of the card and is displayed by the show diag command.
Table 3 lists the hardware and software requirements for Ethernet line cards.

Caution
To prevent system problems, do not use Gigabit Interface Converters (GBICs) from third-party vendors.
Use only the GBIC that shipped with your Ethernet line card. The GBIC might contain an internal
EPROM that identifies it to the Cisco IOS software.
Caution
Only use small form-factor pluggable modules (SFPs) supplied by Cisco in Cisco XR 12000 Series
Routers. Each SFP module contains an internal serial number that is security programmed by the SFP
module manufacturer with information that provides a way for Cisco (through the Cisco IOS software)
to identify and validate the SFP module as a module type that is qualified by Cisco to operate with
Gigabit Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) do not
work.
4-Port Gigabit Ethernet ISE Line Card
The 4-Port Gigabit Ethernet ISE line card provides Cisco XR 12000 Series Routers with four optical
Gigabit Ethernet interfaces on a single line card, using field replaceable SFP modules. The line card
provides high-speed connections to other network devices, such as another Cisco XR 12000 Series
Router, other routers, or layer-2 and layer-3 switches that support Gigabit Ethernet interfaces. The 4-Port
Gigabit Ethernet line card throughput is limited to 4 million packets per second (4 Mpps) at 64 bytes, so
all four ports cannot run at line rate.
Figure 1 shows the front view of the 4-Port Gigabit Ethernet ISE line card.

Preparing for Installation
1-Port 10-Gigabit Ethernet Line Card
The 1-Port 10-Gigabit Ethernet line card provides the supported Cisco XR 12000 Series Routers with
one optical 802.3ae 10-Gigabit Ethernet interface. This interface provides a high-speed connection to
other network devices, such as Cisco XR 12000 Series Routers, or to other routers or layer-2 or layer-3
switches that support 10-Gigabit Ethernet interfaces. Figure 3 shows the front view of the line card.
The port on the front panel of the line card is port number 0. This port uses a hardwired laser optical
transceiver to provide a 10-Gigabit Ethernet optical interface. The transceiver consists of two optical
interfaces—laser transmit (TX) and laser receive (RX)—that use SC connectors.
Next to the port on the line card are three green LEDs, aligned vertically and labeled from top to bottom
as follows: LINK, ACTIVE, and RX FRAME.

Safety Guidelines
Before you perform any procedure in this publication, review the safety guidelines in this section to
avoid injuring yourself or damaging the equipment.
The following guidelines are for your safety and to protect equipment. The guidelines do not include all
hazards. Be alert.
Note
Review the safety warnings listed in the Regulatory Compliance and Safety Information for
Cisco 12000 Series Internet Router publication (Document Number 78-4347-xx) that accompanied your
router before installing, configuring, or maintaining a line card.
•
•
•
Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to
enter into any laser-based components.
Do not wear loose clothing, jewelry, or other items that could get caught in the router while working
with line cards.
Cisco equipment operates safely when it is used in accordance with its specifications and product
usage instructions.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI)
shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap
whenever you are handling network equipment or one of its components.
The following are guidelines for preventing ESD damage:
•
Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the connection cord to an ESD connection socket on the router or to
bare metal on the chassis.
•
•
•
Handle Ethernet line cards by the captive installation screws, the provided handle, ejector levers, or
the line card metal carrier only; avoid touching the board or connector pins.
Place removed Ethernet line cards board-side-up on an antistatic surface or in a static shielding bag.
If you plan to return the component to the factory, immediately place it in a static shielding bag.
Avoid contact between the Ethernet line cards and clothing. The wrist strap only protects the board
from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Warning
For safety, periodically check the resistance value of the ESD strap. The measurement should be
between 1 and 10 megohms.

Refer to the individual line card descriptions in the “Product Overviews” section on page 4 for more
Removing and Installing a Line Card
The following sections provide procedures for removing or installing a line card:
•
•
•
Note
Note
See the “Guidelines for Line Card Removal and Installation” section on page 10 before removing a line
card while power to the router is on.
The procedures in the following sections use illustrations of a Cisco 12012 Internet Router to support
the descriptions of removing and installing line cards. Although the card cages of the Cisco 12000 Series
Routers differ in the number of card slots, the designated use of slots and the process of removing and
installing a line card are basically the same. Therefore, separate procedures and illustrations for other
Cisco routers are not included in this publication.
Guidelines for Line Card Removal and Installation
Guidelines for line card removal and installation include the following:
•
Online insertion and removal (OIR) is supported, enabling you to remove and install line cards while
the router is operating. OIR is seamless to users on the network, maintains all routing information,
and ensures session preservation.
Note
With OIR, notifying the software or resetting the power is not required. However, you have the
option of using the shutdown command before removing a line card.

Removing and Installing a Line Card
•
After you reinstall a line card, the router automatically downloads the necessary software from the
route processor (RP). Next, the router brings online only those interfaces that match the current
configuration and were previously configured as administratively up. You must configure all others
with the configure command.
Caution
The router may indicate a hardware failure if you do not follow proper procedures. Remove
or insert only one line card at a time. Allow at least 15 seconds for the router to complete the
preceding tasks before removing or inserting another line card.
After removing and inserting a line card into the same slot, allow at least 60 seconds before
removing or inserting another line card.
•
Line cards have two ejector levers to release the card from its backplane connector. Use the levers
when you are removing the line card and to seat the line card firmly in its backplane connector when
you are installing the line card. The ejector levers align and seat the card connectors in the
backplane.
Caution
When you remove a line card, always use the ejector levers to ensure that the connector pins
disconnect from the backplane in the sequence expected by the router. Any card that is only
partially connected to the backplane can halt the router.
When you install a line card, always use the ejector levers to ensure that the card is correctly
aligned with the backplane connector; the connector pins should make contact with the
backplane in the correct order, indicating that the card is fully seated in the backplane. If a
card is only partially seated in the backplane, the router will hang and subsequently crash.
Removing a Line Card
If you are replacing a failed line card, remove the existing line card first, then install the new line card
in the same slot. To remove a line card, use Figure 4 as a reference and follow these steps:
Step 1
Step 2
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Disconnect and remove all interface cables from the ports; note the current connections of the cables to
the ports on the line card.
Step 3
Step 4
Detach the line card cable-management bracket from the line card.
Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 4a.)

Step 5
When you remove a line card, always use the ejector levers to ensure that the line card connector pins
disconnect from the backplane in the logical sequence expected by the router. Any line card that is only
partially connected to the backplane can halt the router.
Simultaneously pivot the ejector levers away from each other to release the line card from the backplane
connector. (See Figure 4b.)
Step 6
Step 7
Grasp the ejector levers and pull the line card halfway out of the slot.
Grasp the line card and gently pull it straight out of the slot, keeping your other hand under the line card
to guide it. (See Figure 4c.) Avoid touching the line card printed circuit board, components, or any
connector pins.
Step 8
Step 9
Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan
to return it to the factory.
If the line card slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK)
to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure
the line card blank to the chassis by tightening its captive screws.
Caution
Note
Be careful not to damage or disturb the EMI spring fingers located on the front edge of the card face
plate.
Always insert a dust plug in an optical port opening for each port that is not in use.

For information on disconnecting interface cables, see the “Removing and Installing Fiber-Optic
For information on removing the cable-management bracket, see the “Removing a Line Card
Installing a Line Card
A line card slides into almost any available line card slot and connects directly to the backplane. If you
install a new line card, you must first remove the line card blank from the available slot.
Note
Refer to the installation and configuration guide for your router for information on line card slot types,
slot width, and slot location.
Caution
The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert
only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks
before removing or inserting another line card.
To install a line card, follow these steps:
Step 1
Step 2
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Choose an available line card slot for the line card, and verify that the line card interface cable is long
enough for you to connect the line card with any external equipment.
Caution
Step 3
To prevent ESD damage, handle line cards by the captive installation screws, the provided handle,
ejector levers, or the card carrier edges only. Do not touch any of the electrical components or circuitry.
Grasp the faceplate (or handle) of the line card with one hand and place your other hand under the card
carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid
touching the line card printed circuit board, components, or any connector pins.
Step 4
Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card
cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try
reinserting the line card until the ejector lever hooks are fully latched. (See Figure 5.)

Ejector Levers
When inserting a card, make
sure the ejector lever hooks
catch the lip of the card cage.
Caution
When you install a line card, always use the ejector levers to ensure that the card is correctly aligned
with the backplane connector, the card connector pins make contact with the backplane in the correct
order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane
can cause the router to hang and subsequently crash.
Step 5
Step 6
Simultaneously pivot both ejector levers toward each other until they are perpendicular to the line card
faceplate. This action firmly seats the card in the backplane.
Use a 3/16-inch flat-blade screwdriver to tighten the captive screw on each end of the line card faceplate
to ensure proper EMI shielding and to prevent the line card from becoming partially dislodged from the
backplane.
Caution
To ensure adequate space for additional line cards, always tighten the captive installation screws on each
newly installed line card before you insert any additional line cards. These screws also prevent accidental
removal and provide proper grounding and EMI shielding for the router.

Removing and Installing GBICs
Your Ethernet line card may have shipped with a GBIC installed. If your line card arrived without the
GBIC installed and you need to install it now, or if you need to change your GBIC for another reason,
use the procedures in these sections:
•
•
•
Before you remove or install a GBIC, read the installation information in this section and the “Laser
Note
Cisco strongly recommends that you disconnect all fiber-optic cables before removing or installing a
GBIC.

Removing and Installing GBICs
Caution
To prevent system problems, do not use GBICs from third-party vendors. Use only the GBIC that
shipped with your Gigabit Ethernet line card. These GBICs might contain an internal EPROM that
identifies them to the Cisco IOS software.
Caution
Note
To prevent problems associated with data transmission, you must attach this device only to
IEEE 802.3x-compliant devices.
The Ethernet line card supports online insertion and removal (OIR) of GBICs. This means that you can
remove and replace GBICs while the system remains powered up. When you remove a GBIC, the
interface becomes inactive because a GBIC is not detected in the GBIC receptacle.
General GBIC Handling and Maintenance Guidelines
Follow these GBIC handling and maintenance guidelines:
•
•
•
GBICs are static sensitive. To prevent ESD damage, follow the guidelines described in the
GBICs are dust sensitive. When the GBIC is stored or when a fiber-optic cable is not plugged into
one of the optical ports on the GBIC, always insert an optical port dust plug.
Keep the optical port clean. The most common source of contamination in the optical ports is debris
that collects on the ferrules of the optical cable connectors. Use an alcohol swab or Kim-Wipe to
clean the ferrules of the cable connector before inserting it into the GBIC.
Removing the GBIC from an Ethernet Line Card
To remove the GBIC from an Ethernet line card, follow these steps:
Step 1
Disconnect the SC-type fiber-optic cables from the GBIC. Note which plug is TX and which plug is RX
for reattachment.
Step 2
Step 3
Attach an ESD wrist or ankle strap and follow its directions for use.
Locate the tabs on either side of the exposed portion of the GBIC and squeeze them with your thumb

Inserting a GBIC into the Gigabit Ethernet Interface
To insert a GBIC into the Gigabit Ethernet interface, follow these steps:
Step 1
Step 2
Attach an ESD wrist or ankle strap and follow its directions for use.
Locate the alignment groove on the GBIC. (See the enlargement in Figure 16 on page 24.) Position the
GBIC so that this groove is in the position shown in the enlargement to ensure that the 20-pin plug on
the GBIC is in the correct position.
Caution
Step 3
To prevent damage to the GBIC plug and receptacle before you insert the GBIC into the GBIC slot on
the Gigabit Ethernet interface, ensure that the plug and alignment groove are matched.
Squeeze the tabs on each side of the GBIC using your thumb and forefinger, and insert the GBIC into

Step 4
Step 5
Using moderate force, ensure that the GBIC is fully inserted into the 20-pin receptacle at the rear of the
GBIC slot. The tabs on either side of the GBIC will snap into place when you have completely and
properly inserted the GBIC.
Reattach the SC-type fiber-optic cable to the GBIC.
Removing and Installing SFP Modules
Before you remove or install an SFP module, read the installation information in this section and the
Caution
Protect the SFP modules by inserting clean dust covers into them after the cables are removed. Be sure
to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another
SFP module. Avoid getting dust and other contaminants into the optical ports of your SFP modules,
because the optics will not work correctly when obstructed with dust.
Caution
It is strongly recommended that you do not install or remove the SFP module with fiber-optic cables
attached to it because of the potential of damaging the cable, the cable connector, or the optical interfaces
in the SFP module. Disconnect all cables before removing or installing an SFP module.
Removing and inserting an SFP module can shorten its useful life, so you should not remove and insert
SFP modules any more often than is absolutely necessary.
SFP modules use one of four different latching devices to install and remove the module from a port.
The four types of SFP module latching devices are described in the following sections:
•
•
•
•
Bale Clasp SFP Module

GBIC Laser Optical Transceiver Modules
The Gigabit Interface Converters (GBICs) are field-replaceable modules that plug into receptacles on the
line card and provide the Gigabit Ethernet optical interface. The GBICs have two optical
interfaces—laser transmit (TX) and laser receive (RX)—and an electrical interface (to the line card). All
GBIC module types have dual SC connectors. Different GBICs can be ordered for each port on the line
card. The 1-Port Gigabit Ethernet and 3-Port Gigabit Ethernet line cards use GBICs to provide the
Gigabit Ethernet optical interface.
The following sections provide information on the GBIC and Coarse Wave Division Multiplexing
(CWDM) GBIC in Ethernet line cards:

GBIC Modules
Fiber-optic transmission specifications identify two types of fiber: single-mode and multimode. Signals
can travel farther through single-mode fiber than through multimode fiber.
The 1-Port Gigabit Ethernet and 3-Port Gigabit Ethernet line cards support multimode fiber through the
WS-G5484= GBIC laser optical transceiver module and single-mode fiber through the WS-G5486=,
WS-G5487=. The 3-Port Gigabit Ethernet line card also supports CWDM-GBIC-xxxx= GBIC laser
optical transceiver modules.

optical power budget calculation that takes into consideration all sources of loss, including the insertion loss due to the
CWDM OADM and mux/demux modules, and might be different from the distance shown in the table. For optical parameter

Note
Note
1000BASE-SX and 1000BASE-LX (LH) were originally part of the IEEE 802.3z standard, which has
been incorporated into the IEEE 802.3 standard.
Use only GBIC modules supplied by Cisco with your Ethernet line card. They have been tested by Cisco
Engineering and, in some cases, a Cisco-supplied GBIC might contain an internal erasable
programmable read-only memory (EPROM) that identifies the GBIC to the Cisco IOS software.
The maximum distance for any fiber span in an optical network is determined by the fiber type and
quality, as well as the span length, number of splices, and number of optical nodes in the path. If your
network design requires the signal to travel close to the theoretical maximum distance (as listed in
Table 11), you must calculate the optical power budget and receive (RX) sensitivity for the entire
network topology to ensure it is within the specifications of the GBIC option in use.
Note
Actual power budget calculations involve a number of variables specific to network topology and design,
and are therefore outside the scope of this publication.

Using CWDM GBICs with the 3-Port Gigabit Ethernet Line Card
The 3-Port Gigabit Ethernet line card supports CWDM GBICs. The eight CWDM GBICs available for
use with an Ethernet line card are active components that plug into standard GBIC receptacles in the line
card. They convert Gigabit Ethernet electrical signals into an optical single-mode fiber (SMF) interface
that feeds into a CWDM network through a Cisco optical add/drop multiplexing (OADM) plug-in
appearance of a CWDM GBIC with one optical port dust plug removed.

General CWDM GBIC Installation and Usage Guidelines
The Cisco CWDM GBIC solution has two main components: the Cisco CWDM GBICs and the Cisco
OADM plug-in modules or mux/demux plug-in modules, which are rack mounted in a Cisco CWDM
OADM chassis external to the Cisco 12000 Series Router that contains the Ethernet line card.
The CWDM OADM plug-in modules and mux/demux plug-in modules are passive optical components
that multiplex together multiple wavelengths from multiple SMF fiber pairs into one SMF fiber pair. Up
to two CWDM plug-in modules can be rack-mounted by using the single-rack-unit CWDM chassis.
The CWDM GBICs plug into the standard GBIC receptacles on the faceplate of the Ethernet line card
and are connected to the CWDM OADM or mux/demux plug-in modules in the external CWDM chassis
using SMF jumper cables with SC-type connectors.
A Cisco 12000 Series Router equipped with an Ethernet line card and CWDM GBICs can be connected
into a CWDM network through external CWDM plug-in modules in the following deployment scenarios:
•
Point-to-point—Two endpoints are directly connected via a fiber link. You can add or drop up to
eight Gigabit Ethernet channels into a pair of single-mode fibers.
•
Hub-and-spoke (ring)—Multiple nodes (spokes) are connected with a hub location through a ring
of single-mode fiber. Each hub/node connection can consist of one or more wavelengths, each
carrying a full Gigabit Ethernet channel.
•
Mesh (ring)—Combines the hub-and-spoke and point-to-point (or even multiple point-to-point)
connections in parallel on the same CWDM optic link. The maximum of eight GBIC wavelengths
allows different combinations of these scenarios.

Always connect from transmit (TX) to receive (RX) when connecting GBICs to other equipment:
–
–
Connect GBIC TX to equipment RX
Connect GBIC RX to equipment TX
Optical transceivers—such as the Cisco CWDM GBICs—have a maximum optical receive power,
above which damage might occur to the receive diode. The incoming power level might be too high
if the fiber lacks sufficient attenuation, which might occur in a short run of fiber (less than
approximately 25 km). Attenuators are used to lower the incoming optical signal below the
maximum optical receive power of the Cisco CWDM GBIC (–7 dB).
•
When the length of the fiber-optic link is less than 15.5 miles (25 km), you must insert a 10-dB inline
optical attenuator (Cisco product number AT-10DB-SC=) between the fiber-optic network and the
receiving port on the Cisco CWDM GBIC at each end of the link to ensure that the maximum receive
power is always less than –7 dBm.
Gigabit Ethernet SFP Modules
The Gigabit Ethernet laser optical transceiver module is a field-replaceable small form-factor pluggable
(SFP) module that plugs into the receptacle on the Ethernet port adapter (EPA) located on the Modular
Ethernet line card and provides the Gigabit Ethernet optical interface. (See Figure 35.) The module has
two optical interfaces—laser transmit (TX) and laser receive (RX)—and an electrical interface (to the
line card). The 4-Port Gigabit Ethernet ISE, 10-Port 1-Gigabit Ethernet, and Modular Gigabit Ethernet
line cards use SFP modules.

The following SFP module options are available for a Gigabit Ethernet line card:
•
•
GLC-SX-MM—Short wavelength SFP module (850 nm nominal), for use in 1000BASE-SX links.
GLC-LH-SM—Long-haul or long-wavelength SFP module (1310 nm nominal), for use in
1000BASE-LX links.
•
•
GLC-LX-SM—Single-mode, long-reach
GLC-ZX-SM=—Single-mode, extended-reach (supported by 4-Port Gigabit Ethernet ISE line card
only)
The SFP modules have LC connectors. Different SFP module options allow you to customize the
physical interfaces on the line card by using both types of modules on the same line card. The only
restriction is that each port must match the specifications on the other end of the cable (short or long
wavelength), and must not exceed the recommended cable length for reliable communication.
Fiber-optic transmission specifications identify two types of fiber: single-mode and multimode. The
maximum distance for single-mode installations is determined by the amount of light loss in the fiber
path. If your environment requires the light to travel close to the typical maximum distance, you should
use an optical time domain reflectometer (OTDR) to measure the power loss.
Table 13 describes the operating parameters for the supported SFP modules.

Note
Use only the SFP modules supplied by Cisco with your Gigabit Ethernet line card. Each SFP module
contains an internal serial EEPROM that is security-programmed by the SFP manufacturer with
information that provides a way for Cisco (through the Cisco IOS software) to identify and validate the
SFP module as a module type that was tested and qualified by Cisco to operate properly with Cisco
Gigabit Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) will not
work on the Gigabit Ethernet line card.
10-Gigabit Ethernet
The 1-Port 10-Gigabit Ethernet line card uses single-mode fiber-optic cable. The maximum distance for
single-mode installations is determined by the amount of light loss in the fiber path. If your environment
requires the light to travel close to the typical maximum distance (as listed in Table 16), you should use
an optical time domain reflectometer (OTDR) to measure the power loss.
The Ethernet line card is offered in two transceiver options:
•
•
Long haul or long wavelength, 1310 nanometers (nm) nominal, used for 1000BASE-LR links.
Long haul or long wavelength, 1550 nm nominal, used for 1000BASE-ER links.

Cleaning Fiber-Optic Connectors
Fiber-optic connectors are used to connect two fibers together. When these connectors are used in a
communication system, proper connection becomes a critical factor. They can be damaged by improper
cleaning and connection procedures. Dirty or damaged fiber-optic connectors can result in
communication that is inaccurate or not repeatable.
Fiber-optic connectors differ from electrical or microwave connectors. In a fiber-optic system, light is
transmitted through an extremely small fiber core. Because fiber cores are often 62.5 microns or less in
diameter, and dust particles range from a tenth of a micron to several microns in diameter, dust and any
other contamination at the end of the fiber core can degrade the performance of the connector interface
where the two cores meet. Therefore, the connector must be precisely aligned and the connector interface
must be absolutely free of foreign material.
Connector loss, or insertion loss, is a critical performance characteristic of a fiber-optic connector.
Return loss is also an important factor. Return loss specifies the amount of reflected light: the lower the
reflection, the better the connection. The best physical contact connectors have return losses of better
than –40 dB, but –20 to –30 dB is more common.
The connection quality depends on two factors: the type of connector and the proper cleaning and
connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors
clean at all times, and keep the dust plugs or covers installed when the connectors are not in use.
Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean
the ferrule, the protective tube or cone that surrounds the fiber core, and the end-face surface of the fiber
core.
As a general rule, any time you detect a significant, unexplained loss of light, clean the connectors. To
clean the optical connectors, use a CLETOP fiber optic cleaning cassette (Type A for SC connectors)
and follow the manufacturer’s usage instructions.
If a CLETOP cleaning cassette is not available, follow these steps:

Cabling and Specifications
Step 1
Step 2
Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol and gently wipe the end-face of the
fiber core. Wait 5 seconds for the surfaces to dry and wipe the surfaces a second time.
Use clean, dry, oil-free compressed air to remove any residual dust from the connector.
Warning
Step 3
Invisible laser radiation can be emitted from the aperture of the port when no cable is connected.
Avoid exposure to laser radiation and do not stare into open apertures.
Use a magnifying glass or inspection microscope to inspect the ferrule at angle. Do not look directly into
Type RJ-45 100BASE-T Copper Cables
For an 8-Port Fast Ethernet line card with RJ-45 ports, use an EIA/TIA–568-compliant cable with MDI
wiring and RJ-45 connectors to connect your Cisco XR 12000 Series Router to another router or switch.

Verifying and Troubleshooting the Installation
After installing the hardware, you need to look at the LEDs to verify that the Ethernet line card was
installed correctly. If it was not, you need to troubleshoot to find the problem. The following sections
provide information about how to verify and troubleshoot line card installations:
•
•
•
•
Initial Boot Process
Note
Many new line cards are designated as administratively down by default. Status LEDs are off until you
configure the interfaces and use the no shutdown command.

Verifying and Troubleshooting the Installation
During a typical line card boot process, the following events occur:
1. The line card maintenance bus (MBus) module receives power and begins executing the MBus
software.
2. The line card MBus module determines the type of card on which it resides, performs internal
checks, and prepares to accept the Cisco IOS software from the RP.
3. The RP powers up the line card and loads the line card with its Cisco IOS software.
To verify that the line card is working properly, perform the following operational checks:
•
During the line card boot process, observe the line card alphanumeric LEDs to ensure that the card
is running the typical initialization sequence. The sequence should end with IOS RUN.
•
Observe the line card status LEDs to verify that the Active LED (Link LED or status LED for line
cards with no Active LED) is on. If an Active LED is not on, verify that the associated interface is
not shut down.
Status LEDs
The Gigabit Ethernet line cards and the 8-Port Fast Ethernet line card have different status LEDs.
Gigabit Ethernet Status LEDs
After installing the line card and connecting the interface cables, verify that the line card is working
properly by observing the LEDs on the faceplate. For the locations of the LEDs, refer to the figures in
Status LEDs show the status of each fiber-optic connector:
•
LINK—When lit, indicates that the Gigabit Ethernet (GE) MAC layer is receiving comma characters
from a connected GE device.
•
•
ACTIVE—When lit, indicates that the interface is active.
RX FRAME—When lit, indicates that the interface has received a packet.
Alphanumeric LEDs explain the state of the line card and are made up of two, four-digit alphanumeric
The status LEDs might not go on until after you have configured the line card interfaces (or turned them
on, if they were shut down).
The different operating states of the status LEDs on the Gigabit Ethernet line card are shown in Table 17.

Loss of RX synchronization. Occurs when the receiver cannot detect
commas. For example, removing the local RX cable or the remote TX cable
will cause loss of synchronization.
Invalid word received. To maintain receiver alignment and synchronization,
the receiver looks for a unique detectable code-bit pattern. An invalid word
condition occurs because the receiver detects an incorrect or unsupported
character or sequence of characters, resulting in a loss of synchronization
and a link down condition.

During the line card hardware initialization sequence.
The line is down because of a link failure or problem with the GBIC or SFP
module.

Hardware initialization fails.
The line card interface is shut down, because a GBIC or SFP module was
removed and replaced or was administratively shut down. Note that a newly
inserted line card is designated administratively down, so the Active LED for
the interface remains off until the interface is configured. The Active LED on
the line card does not go on until you configure the line card interface (or turn
the interface on if it was shut down). As an operational check, you can verify
that the card is receiving power by looking at the alphanumeric display
LEDs, which go on when a line card is inserted correctly into the chassis and
is powered on.

Alphanumeric LEDs
Ethernet line cards have two four-digit alphanumeric LED displays at one end of the faceplate, near the
ejector lever, that display a sequence of messages indicating the state of the card. In general, the LEDs
do not turn on until the RP recognizes and powers up the card. As it boots, the line card displays a
sequence of messages similar to those in Table 18.
Note
It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in
Table 18 and Table 19 may not appear on your line card.

Verifying and Troubleshooting the Installation
Troubleshooting the Installation
Note
Many new line cards are designated as administratively down by default. Status LEDs are off until you
configure the interfaces and use the no shutdown command.
If the Active LED (Link LED or status LED for line cards with no Active LED) or the alphanumeric
display LEDs on a line card do not go on, there is either a problem with the line card installation or a
hardware failure. To verify that the line card is installed correctly, follow these steps:
Step 1
Step 2
If the Active LED fails to go on, but the alphanumeric display LEDs on the line card indicate activity,
verify that the initialization sequence ends with IOS RUN. If this is the case, verify that the interface is
not shut down. If it is not, suspect a circuitry problem with the Active LED and contact a service
representative for further assistance.
If the Active LED on the line card fails to go on or the alphanumeric display LEDs do not indicate IOS
RUN, check the router connections as follows:
a. Verify that the line card board connector is fully seated in the backplane. Loosen the captive
installation screws and firmly pivot the ejector levers toward each other until both are perpendicular
to the line card faceplate. Tighten the captive installation screws.
b. Verify that all power cords and data cables are firmly connected at both ends.
c. Verify that all memory modules on the card are fully seated and secured to their sockets.
After the line card reinitializes, the Active LED on the line card should go on. If the Active LED goes
on, the installation is complete; if the Active LED does not go on, proceed to the next step.
Step 3
If the Active LED still fails to go on, remove the Ethernet line card and try installing it in another
available line card slot.
•
If the Active LED goes on when the line card is installed in the new slot, suspect a failed backplane
port in the original line card slot.
•
If the Active LED and alphanumeric display LEDs still do not go on, halt the installation. Contact
a service representative to report the faulty equipment and obtain further instructions.
Step 4
If an error message displays on the console terminal during the line card initialization, see the
appropriate reference publication for error message definitions. If you experience other problems that
you cannot solve, contact a service representative for assistance.
For more information on troubleshooting and diagnostics, refer to the installation and configuration
guide that came with your Cisco 12000 Series Router.
Step 5
Note
If you perform online insertion or removal of the GBIC or SFP without shutting down the
interface, a warning message is displayed on the console device.

For certain memory configurations, the route memory DIMM1 socket can remain empty.
DIMMs must be 3.3V devices.
•
Packet memory DIMMs
–
–
All four DIMM sockets for SDRAM buffer memory must be populated.
Both DIMM sockets for a given buffer pair (either those for the transmit buffer or those for the
receive buffer) must be populated with SDRAM DIMMs of the same type and size.
–
–
Size of the DIMMs in the transmit buffer need not match the size of the SDRAM DIMMs in the
receive buffer.
DIMMs must be 3.3V devices.

If you are upgrading packet memory, both DIMM sockets of a given pair (either the transmit buffer or
the receive buffer) must be populated with a DIMM of the same type and size.
To install DIMMs in a line card, follow these steps:
Step 1
Step 2
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Place the line card on an antistatic mat so that the faceplate is nearest to you.
Caution
To prevent router and memory problems, all DIMMs installed in the line card must be 3.3V devices.
Remove the new DIMM from its protective antistatic bag.
Step 3
Step 4
Grasp the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal
traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket. (See Figure 50.)
Step 5
To position the DIMM for insertion, orient it at the same angle as the DIMM socket. The two notches
(keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in
the socket. (See Figure 50.)
If necessary, rock the DIMM back and forth gently to align it in the socket.

Line Card Memory
Caution
When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If you damage a DIMM
socket, you must return the line card for repair.
Step 6
Step 7
Gently insert the DIMM into the socket and push until the DIMM snaps into place and the release lever
is flush against the side of the socket.
Verify that the release lever is flush against the side of the socket. If it is not, the DIMM might not be
seated properly. On a socket with dual release levers, both levers should be flush against the sides of the
DIMM.
If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush
against the side of the DIMM socket.
Step 8
Repeat Step 3 through Step 7 to install any remaining DIMMs for your memory configuration.
Removing a SODIMM
To remove a SODIMM, follow these steps:
Step 1
Step 2
Step 3
Step 4
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Place the line card on an antistatic mat so that the faceplate is nearest to you.
Locate the route memory socket on the line card.
If present, remove the SODIMM retaining clip from the memory module socket. Grasp the latch arm
intersection located on each side of the clip and gently slide the clip out. (See Figure 51.) Save the
retaining clip.
Note
Some line cards do not require a retaining clip.
Caution
If the retaining clip is bent or damaged, do not attempt to fix or reuse it. This can cause serious damage
to the line card. Each SODIMM replacement ships with a spare retaining clip, in case there is any
damage to the existing clip.

Checking the Installation of Line Card Memory
After you install line card memory and reinstall the line card in the router, the router reinitializes the line
card and detects the memory change as part of the reinitialization cycle. The time required for the router
to initialize can vary with different router configurations and memory configurations.
If the line card does not reinitialize properly after you upgrade memory, or if the console terminal
displays a checksum or memory error, verify that you installed the correct DIMMs and that they are
installed correctly on the line card.
To check the installation of line card memory, follow these steps:
Step 1
Step 2
Check the packet memory DIMMs to verify that both DIMMs are the same type, size, and speed. DIMMs
must operate at 60 ns or faster. The speed of the DIMM is printed along one of its edges.
Check the alignment of the DIMMs by looking at them across the horizontal plane of the card. The
DIMMs should be aligned at the same angle and be fully inserted into their respective sockets. If a
DIMM is not correctly aligned, remove it and reinsert it.
Step 3
Reinstall the line card and perform another installation check.
