Ethernet Line Card Comparison
Table 4 provides comparative information about Ethernet line cards. The first Ethernet line card has a Fast Ethernet interface and the others have a Gigabit Ethernet interface.
![]()
CautionTo 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.
![]()
CautionOnly use small form-factor pluggable modules (SFPs) supplied by Cisco in Cisco 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.
8-Port Fast Ethernet Line Card
The 8-Port Fast Ethernet line card provides eight Fast Ethernet (IEEE 802.3u) interfaces that operate at a full-duplex data rate of 100 Mbps each.
The 8-Port Fast Ethernet line card supports either copper or fiber-optic Fast Ethernet transceivers. The fiber-optic 100BASE-FX interface supports multimode SC duplex connectors operating in half- or full-duplex mode. The copper interface supports both half- and full-duplex 100BASE-TX standards that use an RJ-45 connector.
There are two models, each with updated revisions (-B), of the 8-Port Fast Ethernet line card. The two fiber-optic interface versions are functionally equivalent; the -B model contains some newer ASICs and memory chips, however, and requires a later version of Cisco IOS. The copper interface versions are also both functionally equivalent; the -B model contains some newer ASICs and memory chips and requires a later version of Cisco IOS. The front panels are shown in Figure 1.

Preparing for Installation
The following sections provide information about preparing to install line cards:
•
Preventing Electrostatic Discharge
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.
Before working with laser optics, read the "Laser Safety" section.
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.
Required Tools and Equipment
You need the following tools and parts to remove and install Ethernet line cards:
•
Flat-blade or Phillips screwdriver
•
ESD-preventive wrist or ankle strap and instructions
•
Interface cables to connect the Ethernet line card with another router or switch
•
Any EPAs, GBICs, SFP modules, or memory you need to install (and are not already installed)
![]()
Note
If you need additional equipment, see Cisco.com or your service representative for ordering information.
Refer to the individual line card descriptions in the "Product Overviews" section for more information. Table 4 summarized the hardware requirements for each Ethernet line card.
Removing and Installing a Line Card
The following sections provide procedures for removing or installing a line card:
•
Guidelines for Line Card Removal and Installation
![]()
Note
See the "Guidelines for Line Card Removal and Installation" section before removing a line card while power to the router is on.
![]()
Note
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.
•
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.
![]()
CautionThe 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.
![]()
CautionWhen 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.
For line card configuration information, see the "Configuring and Troubleshooting Line Card Interfaces" section.
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 9 as a reference and follow these steps:
Step 1
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2
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
Detach the line card cable-management bracket from the line card.
Step 4
Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 9a.)
Figure 9 Line Card Removal and Installation

![]()
CautionWhen 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.
Step 5
Simultaneously pivot the ejector levers away from each other to release the line card from the backplane connector. (See Figure 9b.)
Step 6
Grasp the ejector levers and pull the line card halfway out of the slot.
Step 7
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 9c.) Avoid touching the line card printed circuit board, components, or any connector pins.
Step 8
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.
Step 9
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.

For information on removing the cable-management bracket, see the "Removing a Line Card Cable-Management Bracket" section.
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.
![]()
CautionThe 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
Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2
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.
![]()
CautionTo 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.
Step 3
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 10.)
Figure 10 Ejector Levers
![]()
![]()
CautionWhen 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
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.
Step 6
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.
![]()
CautionTo 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.
Step 7
Install the cable-management bracket.
Step 8
Install GBIC or SFP modules, and EPA daughter cards, in the line cards that use them.
Step 9
Install the interface cables.

•
General GBIC Handling and Maintenance Guidelines
•
Removing the GBIC from an Ethernet Line Card
•
Inserting a GBIC into the Gigabit Ethernet Interface
Before you remove or install a GBIC, read the installation information in this section and the "Laser Safety" section.
![]()
Note
Cisco strongly recommends that you disconnect all fiber-optic cables before removing or installing a GBIC.
![]()
CautionTo 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.
![]()
CautionTo prevent problems associated with data transmission, you must attach this device only to IEEE 802.3x-compliant devices.
![]()
Note
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 "Preventing Electrostatic Discharge" section.
•
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
Attach an ESD wrist or ankle strap and follow its directions for use.
Step 3
Locate the tabs on either side of the exposed portion of the GBIC and squeeze them with your thumb and forefinger, as you gently pull the GBIC out of the GBIC slot. (See arrows in Figure 21.)

CautionTo 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.
Step 3
Squeeze the tabs on each side of the GBIC using your thumb and forefinger, and insert the GBIC into the GBIC slot on the Gigabit Ethernet interface. (See Figure 21.)
Step 4
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.
Step 5
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 "Laser Safety" section.
![]()
CautionProtect 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.
![]()
CautionIt 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.

GBIC Laser Optical Transceiver Modules
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:
•
Using CWDM GBICs with the 3-Port Gigabit Ethernet Line Card
•
General CWDM GBIC Installation and Usage Guidelines
•
General Connection Rules for CWDM GBICs
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.

Note
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. To verify the version of the installed GBIC module, refer to "Verifying the GBIC Version" section.
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 15), 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.

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 module or multiplexing/demultiplexing (mux/demux) plug-in module. Figure 39 shows the physical appearance of a CWDM GBIC with one optical port dust plug removed.

The eight CWDM GBICs available for use with a Gigabit Ethernet line card come in eight wavelengths in a range from 1470 nm to 1610 nm. The color dot between the receive and transmit ports and the color band on the label of the Cisco CWDM GBIC identify the wavelength of the GBIC. Table 16 lists the CWDM GBICs and their associated color codes.
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.

•
Installation Note for the CWDM Passive Optical System
General Connection Rules for CWDM GBICs
Observe the following connection rules for CWDM GBICs:
•
Always match the CWDM GBIC color with the equipment port of the same color on the CWDM passive optical system plug-in module.
Use the CWDM passive optical system connector color codes shown in Table 16 to help you connect your router to the CWDM passive optical system.
•
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 40.) 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.
Figure 40 SFP Module and Fiber-Optic Cable
![]()
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 17 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. To verify the version of the installed SFP module, refer to "Verifying the SFP Version" section.
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 20), 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.
Table 19 describes the operating parameters for the transceiver options.
Table 20 lists the power ratings and maximum distances of both models of the Ethernet line cards. The actual distance in any given case depends on the quality of the fiber connected to the transceiver.
Fiber-Optic Interface Cables
Depending on the line card (refer to Table 4), use a single-mode or multimode fiber-optic interface cable with LC-type or SC-type connectors to connect an Ethernet interface on the Ethernet line card in your Cisco 12000 Series Router to another Ethernet interface, router, or switch.
![]()
Note
Fiber optic cables are not available from Cisco Systems. They can be purchased from cable vendors.
The following types of cables are used with Ethernet line cards to connect your router to another router or switch:
•
Single-mode—Generally yellow in color.
•
Multimode—Generally gray or orange in color. Multimode cables are multifiber cables that carry 12 channels of fiber data.

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:
Step 1
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.
Step 2
Use clean, dry, oil-free compressed air to remove any residual dust from the connector.
![]()
Warning
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.
Step 3
Use a magnifying glass or inspection microscope to inspect the ferrule at angle. Do not look directly into the aperture. If you detect any contamination, repeat Step 1 and Step 2.
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 12000 Series Router to another router or switch. Figure 48 shows a typical RJ-45 connector.

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:
•
Troubleshooting the Installation
Troubleshooting using Cisco IOS commands is described the "Configuring and Troubleshooting Line Card Interfaces" section.
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.
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.
If one of these conditions is not met, refer to the "Advanced Line Card Troubleshooting" section to identify any possible problems.
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 the "Product Overviews" section.
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 LED displays. (See the "Alphanumeric LEDs" section.)
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). In order to verify correct operation of each interface, complete the configuration procedures for the line card. (See the "Configuring and Troubleshooting Line Card Interfaces" section.)
The different operating states of the status LEDs on the Gigabit Ethernet line card are shown in Table 21.
8-Port Fast Ethernet Line Card LEDs
Refer to the figures in the "8-Port Fast Ethernet Line Card" section for the locations of the Link LED and the receive and transmit status LEDs. The Link LED is located on the front panel of the line card. The receive and transmit LEDs are located on the side of the line card and are not visible when a line card is fully installed in the Cisco 12000 Series Router. These LEDs signal the status of the port, as explained in Table 22.
s
The Link LED is on under the following conditions:
•
When the line protocol is up. For example, when you enter a no shutdown command as part of the interface configuration.
•
During the 8-Port Fast Ethernet line card hardware initialization.
The Link LED is off under the following conditions:
•
The line is down due to a link failure or problem.
•
Hardware initialization fails.
•
The line card interface is shut down, for example, when you enter a shutdown command as part of the interface configuration.
The status LEDs on the line card do not go on until you have configured the line card interfaces (or turned them on if they were shut down). The alphanumeric display does come on when a line card is inserted correctly into the chassis and is powered on.
To verify correct operation of each interface, complete the configuration procedures for the line card (see the "Configuring and Troubleshooting Line Card Interfaces" section).
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 23.

Note
It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in Table 23 and Table 24 may not appear on your line card.

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
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.
Step 2
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.

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.
Configuring and Troubleshooting Line Card Interfaces
After the person who installed the hardware verifies that the new Ethernet line card is installed correctly by examining the LEDs, the network administrator can configure the new interface. The following sections provide information on configuring and troubleshooting the Ethernet line cards:
•
Configuring Ethernet Line Cards
•
Configuring 802.1Q VLAN Counters
•

•
Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S
Using Configuration Commands
To configure a line card, you enter the correct mode and then enter the commands you need.
First, enter the privileged level of the EXEC command interpreter (privileged EXEC mode) by using the enable command. The system will prompt you for a password if one is set. Next, use the configure command to access configuration mode. If you want to change the default configuration values on the line card, use the configure terminal command to enter global configuration mode. Then, use the interface command to specify the interface and enter interface configuration mode, where you can configure the new interface. Be prepared with the information you will need, such as the interface IP address.
Table 25 lists some configuration commands you may want to use and the default values. Refer to Cisco IOS documentation for complete information about these commands.
A Cisco 12000 Series Router identifies an interface address by its line card slot number and port number, in the format slot/port. The ports on the Ethernet line card are numbered 0, 1, 2, and so on. For example, the slot/port address of the top port on an interface on an Ethernet line card installed in line card slot 1 is 1/0. Even if the line card contains only one port, you must use the slot/port notation.
The Modular Gigabit Ethernet line card identifies an interface address by its line card slot number, EPA number, and port number, in the format slot/EPA_number/port. Table 26 describes the assigned EPA and Gigabit Ethernet port numbers, and how you address a port using Cisco IOS.
For example, to configure gig3, the fourth port on the line card (the first port in the second EPA), you would address slot/1/0. To configure port 9, you would address slot/3/0.
Configuring Ethernet Line Cards
The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration.
To configure an Ethernet line card, you can follow steps like the following:
Step 1
Enter privileged EXEC mode:
Router> enableIf the system prompts you for a password, enter it.
Step 2
Confirm that the system recognizes the card by entering the show version command:
Router# show versionStep 3
Check the status of each port by entering the show interface command:
Router# show interfaceStep 4
Enter global configuration mode and specify that the console terminal will be the source of the configuration commands:
Router# configure terminalStep 5
At the prompt, specify the new interface to configure by entering the interface command, followed by the type (for example, gigabitethernet or fastethernet) and slot/port (line card slot number/port number). For example, to configure port 0 on a 4-Port Gigabit Ethernet ISE line card in line card slot 1:
Router(config)# interface gigabitethernet 1/0You are now in interface configuration mode.
Step 6
Assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example:
Router(config-if)# ip address 10.1.2.3 255.255.255.0Step 7
Change the shutdown state to up and enable the interface:
Router(config-if)# no shutdownThe no shutdown command passes an enable command to the Ethernet line card. It also causes the line card to configure itself based on the most recent configuration commands received by the line card.
Step 8
If you want to disable the Cisco Discovery Protocol (CDP), which is not required, use this command:
Router(config-if)# no cdp enableStep 9
Add any other configuration subcommands required to enable routing protocols and adjust the interface characteristics.
Step 10
When you have included all the configuration subcommands to complete the configuration, enter Ctrl-Z (hold down the Control key while you press Z) to exit configuration mode.
Step 11
Write the new configuration to memory:
Router# copy running-config startup-configThe system displays an OK message when the configuration has been stored.
After you have completed your configuration, you can check it using show commands, as described in the following sections.
Configuring 802.1Q VLAN Counters
On Cisco 12000 Series Gigabit Ethernet and Fast Ethernet line cards, you can configure 802.1Q VLAN subinterfaces to count VLAN traffic by bytes or packets. By default, VLAN traffic statistics are counted in packets. You cannot enable both byte and packet counters.
To configure the way in which 802.1Q VLAN traffic is counted on an Ethernet subinterface, follow these steps:
Step 1
Enter privileged EXEC mode:
Router> enableIf the system prompts you for a password, enter it.
Step 2
Enter global configuration mode.
Router# configure terminalStep 3
Enters subinterface configuration mode to configure the Ethernet subinterface:
Router# interface type slot/port.subinterface-numberStep 4
Specify the type of counter to be used for 802.1Q VLAN traffic statistics on the subinterface.
Router# counter-type {byte | packet}
To display the statistics recorded for 802.1Q VLAN traffic on an Ethernet subinterface, enter the show vlan command in privileged EXEC mode.
Verifying the GBIC Version
You can use the exec slot n show controller gigabitethernet gbic EXEC command to display the GBIC type currently installed in the line card, as shown in the following example:
router# exec slot 4 show controller gigabitethernet 1 gbic========= Line Card (Slot 4) =======** GBIC serial EEPROMidentifier 0x01 (GBIC)connector 0x01 (FibreChannel SC)gbic transceiver_code0x01 1000BASE-SXencoding 0x01 (8B10B)br_nominal (units of 100MHz) 13length_9u (units of 100m) 0length_50u (units of 100m) 50length_62_5u (units of 100m) 22length_cu (unit of 10m) 0vendor_name HEWLETT-PACKARDvendor_oui 0x00 00 00vendor_pn 0x48464252 2D353630 31202020 20202020vendor_rev 0x30303030 0000cc_base 0x74options[0] 0x1A LOS (Loss of Signal) TX Fault TX Disablebr_max (upper baud rate margin, units of %)0br_min (upper baud rate margin, units of %)0vendor_sn 0x39383037 31303037 34383539 36363933date_code 98071000 (yymmddvv, v=vendor specific)Verifying the SFP Version
Use the show interfaces gigabitethernet command to display the SFP module type currently installed in a port on the line card. For example:

This section provides advanced troubleshooting information in the event of a line card failure. It also provides pointers for identifying whether or not the failure is hardware related. This section does not include any software-related failures, except for those that are often mistaken for hardware failures.
![]()
Note
This section assumes that you possess basic proficiency in the use of Cisco IOS software commands.
By reading this section and by following the troubleshooting steps, you should be able to determine the nature of the problems you are having with your line card. The first step is to identify the cause of the line card failure or console errors that you are seeing. To discover which card may be at fault, it is essential to collect the output from the following commands:
•
show context summary
•
show logging
•
show logging summary
•
show diag slot
•
show context slot slot
Along with these show commands, you should also gather the following information:
•
Console Logs and Syslog Information—This information is crucial if multiple symptoms are occurring. If the router is configured to send logs to a Syslog server, you may see some information on what has occurred. For console logs, it is best to be directly connected to the router on the console port with logging enabled.
•
Additional Data—The show tech-support command is a compilation of many different commands, including show version, show running-config, and show stacks. This information is required when working on issues with the Cisco Technical Assistance Center (TAC).
![]()
Note
It is important to collect the show tech-support data before doing a reload or power cycle. Failure to do so can cause all information about the problem to be lost.
![]()
Note
Output from these commands will vary slightly depending on which line card you are using, but the basic information will be the same.

The three most common types of line card failures are:
•
Software Forced Crash (SIG=23)
•
Bus Error (SIG=10)
•
Cache Parity Exception (SIG=20)
In the example above, the line card has failed and has caused a reload because of a software forced crash exception. Once you have determined the cause and collected the necessary output, you can check for any caveats in your Cisco IOS software release using the Bug Toolkit (available to registered Cisco.com users only).
Checking the Current Status of the Line Card
Once you have determined if the problems are caused by system errors in the log or an actual crash, it is important to check the current status of the line card to see if it has recovered from the failure. The status of individual line cards can be identified either by examining the alphanumeric LEDs located on the front of the line card, or by issuing the show led command.
show led Output

Note
It is possible for the value of an alphanumeric LED to be reversed. For example, IOS RUN may be displayed as RUN IOS.
If the alphanumeric LEDs on the line card display anything other than IOS RUN, or the RP is neither the active Master/Primary nor the Slave/Secondary, there is a problem and the line card has not fully loaded correctly. Before replacing the line card, try fixing the problem by following these steps:
Step 1
Reload the microcode using the global configuration microcode reload slot command.
Step 2
Reload the line card using the hw-module slot reload command. This causes the line card to reset and download the MBus and fabric downloader software modules before attempting to download the Cisco IOS software.
or
Step 3
Reset the line card manually. This may rule out any problems that are caused by a bad connection to the MBus or switching fabric.
Fabric Ping Failure
Fabric ping failures occur when either a line card or the secondary RP fails to respond to a fabric ping request from the primary RP over the switch fabric. Such failures are a problem symptom that should be investigated. They are indicated by the following error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure%LCINFO-3-CRASH: Line card in slot 1 crashedYou can find more information about this issue on Cisco.com in the Troubleshooting Fabric Ping Timeouts and Failures on the Cisco 12000 Series Internet Router publication.
Error Messages
If you receive any error message related to a line card, you can use the Error Message Decoder Tool (on Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This publication does not cover all these messages.

If the line card does not boot and you receive an error message indicating that there is a problem with the Field-Programmable Gate Array (FPGA) image (or if the line card alphanumeric LED display remains frozen in IOS STRT state), you need to upgrade the FPGA image using the update-fpga option in the diag command.
![]()
Note
The diag command and the update-fpga option are documented in the Field Diagnostics for the Cisco 12000 Series Internet Router publication.
When the Cisco IOS image boots, it verifies that a compatible FPGA image is running on the router. The major version number of the FPGA image must be the same as that expected by the Cisco IOS image; the minor version number on the FPGA image must be the same as or greater than the minor version number expected by the Cisco IOS image. For example, if the Cisco IOS image expects a minimum FPGA image of 03.02, the software will verify that the actual major version number of the FPGA image in the line card bootflash is 03, and that the minor version number is 02 or above.
Example error messages indicating an FPGA problem appear as follows:
Error Message No FPGA image available for slot0. Please run field diagnostics image on slot0 to upgrade the FPGA image.Explanation There is currently no valid FPGA image in the bootflash of the line card. You must load a valid FPGA image to the line card bootflash.
Error Message FPGA image not appropriate or corrupted for slot0. Please run field diagnostics on slot0 to upgrade the FPGA image.Explanation The FPGA image currently loaded in the line card bootflash is not compatible with the Cisco IOS software release currently running on the router or is corrupted. Upgrade the FPGA image to the correct version.
![]()
Note
Do not confuse the line card bootflash with the route processor (RP) bootflash. FPGA images are loaded only to the line card bootflash.

Note
FPGA error messages are only applicable to 4-Port Gigabit Ethernet ISE line cards.
Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later
![]()
Note
Output from this procedure will vary slightly depending on which line card you are using, but the basic information will be the same.
Line card field diagnostic software is designed to identify any faulty line card within a Cisco 12000 Series Router. Before Cisco IOS Software Release 12.0(22)S, the field diagnostic software was imbedded within the Cisco IOS software. Starting with Cisco IOS Software Release 12.0(22)S, this software is unbundled from the main image and must be downloaded from Cisco.com using the IOS Upgrade Planner.
Cisco initiated this change to accommodate users with 20-MB Flash memory cards. Field diagnostics are now stored and maintained as a separate image under the following name:
c12k-fdiagsbflc-mz-xxx-xx.s (where xxx-xx is the version number)
This image must be available on a separate Flash memory card, Flash disk, or TFTP boot server in order to load line card field diagnostics. The latest version is always available on Cisco.com. RP and fabric tests remain embedded within the main Cisco IOS software image.
While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing (5 to 20 minutes depending upon the complexity of the line card). Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems. The output of the diagnostic test without the verbose command appears like the following example:

Field diagnostic results are stored in an electrically erasable programmable read-only memory (EEPROM) on the line card. It is possible to view the results of the last diagnostic test performed on the line card by executing the diag slot previous command.
There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty. As a precaution, if the line card fails and had been replaced previously, you should review this output with the Cisco TAC.

Removing and Installing Line Card Memory
Before beginning the memory replacement procedures in this section, ensure that you have the proper tools and equipment at hand, and that you are using appropriate ESD-prevention equipment and techniques. Before removing or installing memory, observe the following guidelines:
•
Route memory DIMMs
–
Route memory DIMM0 socket must always be populated.
–
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.
Instructions are in the following sections:

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
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.
Step 2
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.
If the router fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, however, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem.

Obtaining Technical Assistance
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, the Cisco Technical Assistance Center (TAC) provides 24-hour-a-day, award-winning technical support services, online and over the phone. Cisco.com features the Cisco TAC website as an online starting point for technical assistance. If you do not hold a valid Cisco service contract, please contact your reseller.
Cisco TAC Website
The Cisco TAC website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The Cisco TAC website is available 24 hours a day, 365 days a year. The Cisco TAC website is located at this URL:
Accessing all the tools on the Cisco TAC website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a login ID or password, register at this URL:

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:
http://www.cisco.com/tac/caseopen
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete listing of Cisco TAC contacts, go to this URL:

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
