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

The following sections provide information about preparing to install line cards:

• Safety Guidelines, page 9

• Preventing Electrostatic Discharge, page 9

• Required Tools and Equipment, page 10

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.

Preparing for Installation

• 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 on page 82.

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. We recommend 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.

OL-7861-01

• 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.

Cisco XR 12000 Series Router Ethernet Line Card Installation

Removing and Installing a Line Card

• Avoid contact between the Ethernet line cards and clothing. The wrist strap protects the board from

ESD voltages on the body only; 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 on page 4 for more information. Table 4 on page 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, page 11

• Removing a Line Card, page 11

• Installing a Line Card, page 13

Note See the “Guidelines for Line Card Removal and Installation” section on page 11 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.

Cisco XR 12000 Series Router Ethernet Line Card Installation

OL-7861-01

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.

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.

Removing and Installing a 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 hangs and subsequently crashes.

Removing a Line Card

OL-7861-01

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 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Cisco XR 12000 Series Router Ethernet Line Card Installation

Removing and Installing a Line Card

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 4a.)

Caution 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.

Step 5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane

connector. (See Figure 4b.)

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 4c.) 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.

Cisco XR 12000 Series Router Ethernet Line Card Installation

OL-7861-01

Caution Be careful not to damage or disturb the EMI spring fingers located on the front edge of the card face

plate.

Note 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

Interface Cables” section on page 52.

For information on removing the cable-management bracket, see the “Removing a Line Card

Cable-Management Bracket” section on page 39.

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.

Removing and Installing a Line Card

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 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.

Caution 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.

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 5.)

OL-7861-01

Cisco XR 12000 Series Router Ethernet Line Card Installation

Removing and Installing a Line Card

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.

H7681

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.

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.

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.

For information on installing cable-management brackets, see the “Installing a Line Card

Cable-Management Bracket” section on page 41.

For information on installing EPAs, see the “Removing and Installing EPAs” section on page 15.

For information on installing GBICs, see the “Removing and Installing GBICs” section on page 23.

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:

• General GBIC Handling and Maintenance Guidelines, page 24

• Removing the GBIC from an Ethernet Line Card, page 24

• Inserting a GBIC into the Gigabit Ethernet Interface, page 25

Before you remove or install a GBIC, read the installation information in this section and the “Laser

Safety” section on page 82.

Note Cisco strongly recommends that you disconnect all fiber-optic cables before removing or installing a

GBIC.

129856

OL-7861-01

Cisco XR 12000 Series Router Ethernet Line Card Installation

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 To 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 on page 9.

• 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 16.)

Inserting a GBIC into the Gigabit Ethernet Interface

To insert a GBIC into the Gigabit Ethernet interface, follow these steps:

Step 1 Attach an ESD wrist or ankle strap and follow its directions for use.

Step 2 Locate the alignment groove on the GBIC. (See the enlargement in Figure 16 on page 25.) 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 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.

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 16 on page 25.)

OL-7861-01

Cisco XR 12000 Series Router Ethernet Line Card Installation

Removing and Installing SFP Modules

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 on page 82.

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, page 26

• Mylar Tab SFP Module, page 29

• Actuator Button SFP Module, page 32

• Slide Tab SFP Module, page 34

Bale Clasp SFP Module

The bale clasp SFP module has a clasp that you use to remove or install the SFP module. (See Figure 17.)

Fast Ethernet Interface

The term Ethernet is commonly used for all carrier sense, multiple access/collision detection (CSMA/CD) local-area networks (LANs) that conform to Ethernet specifications, including Fast Ethernet defined by IEEE 802.3u.

IEEE 802.3u specifies the following different physical layers for 100BASE-T:

• 100BASE-TX—100BASE-T, half- and full-duplex over Category 5 unshielded twisted-pair (UTP),

Electronics Industry Association/Telecommunications Industry Association [EIA/TIA]–568-compliant cable.

Note The 8-Port Fast Ethernet line card provides an RJ-45 connector that follows the

Media-Dependent Interface (MDI) port wiring standard, as opposed to the Media-Dependent Interface-crossed (MDI-X) wiring scheme found on many hubs and repeaters.

Cisco XR 12000 Series Router Ethernet Line Card Installation

OL-7861-01

Cabling and Specifications

• 100BASE-FX—100BASE-T, half- and full-duplex over fiber-optic cable.

Note 100BASE-TX and 100BASE-FX are commonly called 100BASE-X rather than

100BASE-T.

• 100BASE-T4—100BASE-T, half- and full-duplex over Category 3, 4, or 5 UTP or shielded

twisted-pair (STP) cabling with four pairs, also called 4T+. Two-pair UTP over Category 3 cable is called T2.

Note The 8-Port Fast Ethernet line card supports 100BASE-TX and 100BASE-FX. 100BASE-T4

is not supported.

Table 8 lists the cabling specifications for 100 Mbps Fast Ethernet transmission over UTP, STP, and

fiber-optic cables. Table 9 summarizes IEEE 802.3u 100BASE-T physical characteristics for 100BASE-TX and 100BASE-FX.

Gigabit Ethernet Interface

This section describes the Gigabit Ethernet interface:

• GBIC Laser Optical Transceiver Modules, page 44

• Gigabit Ethernet SFP Modules, page 48

• 10-Gigabit Ethernet, page 50

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:

• Related CWDM Documentation, page 47

• General Connection Rules for CWDM GBICs, page 47

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.

In the case of the CWDM GBICs, CWDM OADM modules or mux/demux modules are needed for these GBICs to work in any topology other than a point-to-point topology within one building, so the maximum distance is determined by an 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 information associated with the CWDM OADM and mux/demux modules, see the “Related CWDM Documentation” section

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.

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 module or multiplexing/demultiplexing (mux/demux) plug-in module. Figure 34 shows the physical 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.

Cabling and Specifications

• 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.

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.

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 Tab le 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:

Table 15 describes the operating parameters for the 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.

Cabling and Specifications

• 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.

Note For network applications using CWDM GBICs in Ethernet line cards, the CWDM GBICs use SMF patch

cords only. Verify that all your patch cords are yellow (SMF), rather than orange (MMF).

The following types of cable connectors are used with Ethernet line cards:

• Subscriber connector (SC)—See Figure 36 and Figure 37

• Lucent connector (LC)— See Figure 38 and Figure 39

You can use two cables with simplex connectors, or one cable with dual, keyed connectors.

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.

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.

Cisco XR 12000 Series Router Ethernet Line Card Installation

OL-7861-01

Cabling and Specifications

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

Step 3 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.

Figure 43 shows a typical RJ-45 connector.

To remove line card cables, follow these steps (refer to Figure 44 on page 58):

Step 1 Attach an ESD-preventive wrist or ankle strap to your wrist and follow its instructions for use.

Step 2 Disconnect the interface cable connectors from the line card interface ports.

Note You do not have to remove the interface cables from the line card cable-management bracket.

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, page 59

• Status LEDs, page 59

• Alphanumeric LEDs, page 60

Cisco XR 12000 Series Router Ethernet Line Card Installation

OL-7861-01

• Troubleshooting the Installation, page 64

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.

Verifying and Troubleshooting the Installation

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 on page 4.

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 on page 60.)

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 Tab le 17.

• A signal is detected.

• There is RX synchronization.

• The GBIC or SFP module is inserted and has no fault conditions.

• The line card is connected to another functioning Gigabit Ethernet interface

and has received comma-detect characters.

• Loss of signal (LOS). Occurs when the signal is lost at the optical input. For

example, removing a GBIC or SFP or removing a cable causes both an LOS and a loss of synchronization.

• 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.

• When the line protocol is up. For example, you enter a no shutdown

command as part of the interface configuration.

• 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

1. This LED sequence only appears in Cisco IOS release 12.0(24)S or later.

2. The fabric downloader loads the Cisco IOS software image onto the 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.

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.

Regulatory, Compliance, and Safety Information

Modifying the equipment without Cisco’s authorization may result in the equipment no longer complying with FCC requirements for Class A digital devices. In that event, your right to use the equipment may be limited by FCC regulation and you may be required to correct any interference to radio or television communication at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is,

make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
