---

Caution To prevent system problems, do not use Gigabit Interface Converters (GBICs) from third-party vendors. Use only the GBIC that shipped with your Ethernet line card. The GBIC might contain an internal EPROM that identifies it to the Cisco IOS software.

---

---

Caution Only use small form-factor pluggable modules (SFPs) supplied by Cisco in Cisco XR 12000 Series Routers. Each SFP module contains an internal serial number that is security programmed by the SFP module manufacturer with information that provides a way for Cisco (through the Cisco IOS software) to identify and validate the SFP module as a module type that is qualified by Cisco to operate with Gigabit Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) do not work.

Preparing for Installation

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

•Safety Guidelines

•Preventing Electrostatic Discharge

•Required Tools and Equipment

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. 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.

•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 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 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

•Removing a Line Card

•Installing a Line Card

---

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.

---

Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.

After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or inserting another line card.

---

•Line cards have two ejector levers to release the card from its backplane connector. Use the levers when you are removing the line card and to seat the line card firmly in its backplane connector when you are installing the line card. The ejector levers align and seat the card connectors in the backplane.

---

Caution When you remove a line card, always use the ejector levers to ensure that the connector pins disconnect from the backplane in the sequence expected by the router. Any card that is only partially connected to the backplane can halt the router.

When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector; the connector pins should make contact with the backplane in the correct order, indicating that the card is fully seated in the backplane. If a card is only partially seated in the backplane, the router hangs and subsequently crashes.

---

Removing a Line Card

If you are replacing a failed line card, remove the existing line card first, then install the new line card in the same slot. To remove a line card, use Figure 4 as a reference and follow these steps:

---

Step 1 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 4a.)

Figure 4 Line Card Removal and Installation

---

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.

---

---

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.

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.

---

---

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.)

Figure 5 Ejector Levers

---

Caution When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the router to hang and subsequently crash.

---

Step 5 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.

For information on installing EPAs, see the "Removing and Installing EPAs" section.

For information on installing GBICs, see the "Removing and Installing GBICs" section.

Figure 7 Removing an EPA

If the EPA bay is to remain empty, install an EPA blank (Product Number MAS-EPA-BLANK=) to keep dust out of the line card and to maintain proper airflow and EMI through the line card and chassis.

Inserting an EPA into a Modular Gigabit Ethernet Line Card

To insert an EPA into the Modular Gigabit Ethernet line card, follow these steps:

Warning You must use an ESD-preventive wrist or ankle strap to do this procedure. Attach an ESD-preventive wrist or ankle strap and follow its directions for use, before you do this procedure.

---

Step 1 First, read the yellow caution label on the EPA. Figure 8 shows a sample of this caution label.

Figure 8 Locations of Labels and Reference Points on the EPA

---

Caution The connectors must be engaged without any angular misalignment. Engaging the connectors at an angle will cause damage to the connectors.

---

Step 2 Ensure that the connector guide pins are aligned, and mate the connector of the EPA to the connector on the line card, as shown in Figure 9 and Figure 10. Figure 10 shows two side views of the EPA and line card.

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

•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.

---

---

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.

•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.) 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.)

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.

---

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

•Mylar Tab SFP Module

•Actuator Button SFP Module

•Slide Tab SFP Module

Line Card Cable-Management Bracket

---

Note The illustrations in this section show various line cards, but the line card cable-management bracket installation procedure is the same regardless of the specific line card.

---

Cisco XR 12000 Series Routers include a cable-management system that organizes the interface cables entering and exiting the router, keeping them out of the way and free of sharp bends.

---

Caution Excessive bending of interface cables can damage the cables.

---

The cable-management system consists of two separate components:

1. A cable-management tray that is mounted on the chassis. Refer to the appropriate Cisco XR 12000 Series Router installation and configuration guide for more information on the cable-management tray.

2. A cable-management bracket that attaches to a line card.

This section describes the line card cable-management bracket. Figure 30 shows the single-port line card cable-management bracket; Figure 31 shows the multiport line card cable-management bracket.

Figure 30 Single-Port Line Card Cable-Management Bracket

Figure 31 Multiport Line Card Cable-Management Bracket

---

Note When shipped with spare line card orders, the cable-management bracket is not attached to the line card. You must attach the cable-management bracket to the line card before you insert the line card into the router.

---

---

Caution Do not use the cable-management bracket as a handle to pull out or push in the line card. The cable-management bracket is designed to hold the interface cables and may break if you use the bracket to push, pull, or carry the line card after it is removed from the router.

Cabling and Specifications

The following sections provide information about specifications and cabling for Ethernet line cards:

•Fast Ethernet Interface

•Gigabit Ethernet Interface

•Fiber-Optic Interface Cables

•Removing and Installing Fiber-Optic Interface Cables

•Cleaning Fiber-Optic Connectors

•Type RJ-45 100BASE-T Copper Cables

•Removing and Installing RJ-45 100BASE-T Copper Cable

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.

---

•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

•Gigabit Ethernet SFP Modules

•10-Gigabit Ethernet

GBIC Laser Optical Transceiver Modules

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

The following sections provide information on the GBIC and Coarse Wave Division Multiplexing (CWDM) GBIC in Ethernet line cards:

•GBIC Modules

•Using CWDM GBICs with the 3-Port Gigabit Ethernet Line Card

•General CWDM GBIC Installation and Usage Guidelines

•Related CWDM Documentation

•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.

Table 10 describes the operating parameters for available GBIC laser optics.

Table 10 Ethernet GBIC Laser Optic Parameters  

GBIC Module/ Connector	Type	Wavelength	Fiber Type	Distance 1
WS-G5484= SC connector	Shortwave (multimode shorthaul) Defined by 1000BASE-SX standard, IEEE 802.3	850 nm	62.5 micron MMF	902 feet (275 m)
			50 micron MMF	1804 feet (550 m)
WS-G5486= SC connector	Longwave (single-mode longhaul) Compliant with 1000BASE-LX standard, IEEE 802.3	1310 nm	10/9 micron SMF	6.2 miles (10 km)
WS-G5487= SC connector	Extended distance (single-mode)	1550 nm	10/9 micron SMF	43.5 miles (70 km)
			8 micron SMF2	62 miles (100 km)
CWDM-GBIC-xxxx=3	Longwave (single-mode)	1470-1610 nm4	SMF 10/9 micron	62 miles (100 km)

1 These distances represent best case conditions, depending on fiber quality, dispersion, and losses due to connectors, nodes, or splices. 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. 2 Dispersion-shifted single-mode fiber-optic cable required for 100,000-meter distance. 3 Supported by 3-Port Gigabit Ethernet modules 4 The wavelengths of the CWDM GBICs are based on a 20-nanometer (nm) wavelength grid and are available in eight wavelengths: 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm.

---

Note 1000BASE-SX and 1000BASE-LX (LH) were originally part of the IEEE 802.3z standard, which has been incorporated into the IEEE 802.3 standard.

---

---

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.

---

Table 11 Optical Parameter Values for Calculating Link Power Budget  

GBIC	Transmit Power	Receive Power	Receive Sensitivity	Link Budget	Maximum Distance 1
WS-G5484=	-9.5dBm to 0 dBm2	-17 to 0 dBm	-17 dBm	7.5 dB	1,804 feet (550 m)
WS-G5486=	-11 to -3 dBm	-19 to -3 dBm	-19 dBm	8 dB	6.2 miles (10 km)
WS-G5487=	0 to +5 dBm	-23 to 0 dBm	-23 dBm	23 dB	43.5 to 62 miles (70 to 100 km3 )
CWDM-GBIC-xxxx=	+1 to +5 dBm	-31 to -7 dBm	-31 dBm	32 dB	62 miles (100 km)4

1 These distances represent best case conditions, depending on fiber quality, dispersion, and losses due to connectors, nodes, or splices. 2 dBm = decibels referenced to 1 milliwatt. 3 Dispersion-shifted single-mode fiber-optic cable required for 100-km distance. 4 This distance represents best case conditions, depending on fiber quality, dispersion, and losses due to connectors, nodes, or splices. 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.

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.

Figure 34 CWDM GBIC (Yellow-Coded CWDM-GBIC-1550= Shown)

1	Color band on label	4	Transmit optical bore	6	Receive optical bore
2	Alignment groove	5	Optical bore dust plug	7	Color dot
3	Spring clip

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 12 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 12 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 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.

Figure 35 SFP Module and Fiber-Optic Cable

1	Component side of line card	3	Card carrier side of line card
2	Top surface of SFP module

The following SFP module options are available for a Gigabit Ethernet line card:

•GLC-SX-MM—Short wavelength SFP module (850 nm nominal), for use in 1000BASE-SX links.

•GLC-LH-SM—Long-haul or long-wavelength SFP module (1310 nm nominal), for use in 1000BASE-LX links.

•GLC-LX-SM—Single-mode, long-reach

•GLC-ZX-SM=—Single-mode, extended-reach (supported by 4-Port Gigabit Ethernet ISE line card only)

The SFP modules have LC connectors. Different SFP module options allow you to customize the physical interfaces on the line card by using both types of modules on the same line card. The only restriction is that each port must match the specifications on the other end of the cable (short or long wavelength), and must not exceed the recommended cable length for reliable communication.

Fiber-optic transmission specifications identify two types of fiber: single-mode and multimode. The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. If your environment requires the light to travel close to the typical maximum distance, you should use an optical time domain reflectometer (OTDR) to measure the power loss.

Table 13 describes the operating parameters for the supported SFP modules.

Table 13 Gigabit Ethernet SFP Module Power Budget and Signal Requirements

---

Note Use only the SFP modules supplied by Cisco with your Gigabit Ethernet line card. Each SFP module contains an internal serial EEPROM that is security-programmed by the SFP manufacturer with information that provides a way for Cisco (through the Cisco IOS software) to identify and validate the SFP module as a module type that was tested and qualified by Cisco to operate properly with Cisco Gigabit Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) will not work on the Gigabit Ethernet line card.

---

10-Gigabit Ethernet

The 1-Port 10-Gigabit Ethernet line card uses single-mode fiber-optic cable. The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. If your environment requires the light to travel close to the typical maximum distance (as listed in Table 16), you should use an optical time domain reflectometer (OTDR) to measure the power loss.

The Ethernet line card is offered in two transceiver options:

•Long haul or long wavelength, 1310 nanometers (nm) nominal, used for 1000BASE-LR links.

•Long haul or long wavelength, 1550 nm nominal, used for 1000BASE-ER links.

Table 15 describes the operating parameters for the transceiver options.

Table 15 10-Gigabit Ethernet Laser Optical Transceiver Operating Parameters  

Transceiver Option	Type	Wavelength	Cable	Distance
LR	Long wavelength (single-mode long haul)	1310 nm	SMF 9/125 micron	6.2 miles (10 km)
ER	Long wavelength (single-mode long haul)	1550 nm	SMF 9/125 micron	24.9 miles (40 km)

Table 16 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.

Table 16 Transceiver Module Power Budget and Signal Requirements 

Transceiver Option	Power Budget	Transmit Power	Receive Power	Typical Maximum Distance
LR	6.2 dB	-8.2 to +0.5 dBm at 1310 nm	-14.4 to +0.5 dBm	6.2 miles (10 km)
ER	11.1 dB	-4.7 to +4 dBm at 1550 nm	-15.8 to -1 dBm	24.9 miles (40 km)

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 XR 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.

---

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.

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.

Figure 44 Attaching RJ-45 Copper Cables

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

•Status LEDs

•Alphanumeric LEDs

•Troubleshooting the Installation

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.

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).

The different operating states of the status LEDs on the Gigabit Ethernet line card are shown in Table 17.

Table 17 Status LED Descriptions 

LED	Color/Activity	Description
LINK	Green	· 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.
	Off	· 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.
ACTIVE	Green	· 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.
	Off	· 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.
RX FRAME	Green	Packets are being received on this interface.
	Off	Packets are not being received on this interface.

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.

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.

Step 5

---

Note If you perform online insertion or removal of the GBIC or SFP without shutting down the interface, a warning message is displayed on the console device.

Ethernet Line Card Route Memory Options

Route memory runs the Cisco IOS software image and stores updated network routing tables downloaded from the route processor (RP). Line card route memory ranges from 128 MB to 256 MB. Table 21 lists the available route memory configurations and associated product numbers of the memory modules used for upgrading route memory on Ethernet line cards.

Table 21 Route Memory Configurations for Ethernet Line Cards 

Total Route Memory	Cisco Product Number	DIMM Module	Route Memory DIMM Sockets
64 MB	MEM-GRP/LC-64=1	1 64-MB DIMM	DIMM0 or DIMM1
128 MB	MEM-DFT-GRP/LC-128	1 128-MB DIMM	DIMM0 or DIMM1
128 MB	MEM-GRP/LC-128=	1 128-MB DIMM	DIMM0 or DIMM1
256 MB	MEM-GRP/LC-256=	2 128-MB DIMMs	DIMM0 and DIMM1
256 MB	MEM-LC4-256=2	1 256-MB SODIMM	Varies

1 This option adds a second 64-MB DIMM for a total of 128 MB for line cards that are equipped with 64 MB. 2 This option is only compatible with the 4-Port Ethernet line cards and is for replacement only.

If you are upgrading or replacing line card route and packet memory, refer to the Cisco XR 12000 Series Router Memory Replacement Instructions publication for installation procedures and the most up-to-date memory options.

Ethernet Line Card Packet Memory Options

Line card packet memory temporarily stores data packets awaiting switching decisions by the line card processor. Once the line card processor makes the switching decisions, the packets are propagated into the router switch fabric for transmission to the appropriate line card.

Table 22 lists the packet memory options for Ethernet line cards.

1 The SDRAM DIMMs installed in a given buffer (either receive or transmit) must be the same type and size, but the individual receive and transmit buffers can operate with different memory capacities.

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:

•Removing a DIMM

•Installing a DIMM

•Removing a SODIMM

•Installing a SODIMM

•Checking the Installation of Line Card Memory

Removing a DIMM

To remove a DIMM from a line card, follow these steps:

---

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

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 Locate the DIMM sockets on the line card.

---

Note Some line cards use DIMM sockets equipped with dual release levers, as shown in Figure 48; other line cards use DIMM sockets equipped with a single release lever, as shown in Figure 49. Both DIMM sockets operate in the same general way.

---

Figure 48 DIMM Socket with Dual Release Levers

Figure 49 DIMM Socket with Single Release Lever

Step 4 Use the socket release levers to eject the DIMM.

•For a socket with dual release levers (see Figure 48), pull down both levers at the same time to eject the DIMM.

or

•For a socket with a single release lever (see Figure 49), pull the lever to eject the DIMM.

---

Caution Handle the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket.

---

Step 5 As one end of the DIMM is released, grasp the top corners of the DIMM with the thumb and forefinger of each hand and pull the DIMM completely out of its socket.

Step 6 Immediately place the DIMM in an antistatic bag to protect it from ESD damage.

Step 7 Repeat Step 4 through Step 6 for any remaining DIMMs that you want to remove.

---

Installing a DIMM

This section contains instructions for installing DIMM memory into a line card.

---

Note If you are upgrading packet memory, both DIMM sockets of a given pair (either the transmit buffer or the receive buffer) must be populated with a DIMM of the same type and size.

---

To install DIMMs in a line card, follow these steps:

---

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

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

---

Caution To prevent router and memory problems, all DIMMs installed in the line card must be 3.3V devices.

---

Step 3 Remove the new DIMM from its protective antistatic bag.

Step 4 Grasp the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket. (See Figure 50.)

Step 5 To position the DIMM for insertion, orient it at the same angle as the DIMM socket. The two notches (keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in the socket. (See Figure 50.)

If necessary, rock the DIMM back and forth gently to align it in the socket.

Figure 50 Handling a DIMM

---

Caution When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If you damage a DIMM socket, you must return the line card for repair.

---

Step 6 Gently insert the DIMM into the socket and push until the DIMM snaps into place and the release lever is flush against the side of the socket.

Step 7 Verify that the release lever is flush against the side of the socket. If it is not, the DIMM might not be seated properly. On a socket with dual release levers, both levers should be flush against the sides of the DIMM.

If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the DIMM socket.

Step 8 Repeat Step 3 through Step 7 to install any remaining DIMMs for your memory configuration.

---

Removing a SODIMM

To remove a SODIMM, follow these steps:

---

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

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 Locate the route memory socket on the line card.

Step 4 If present, remove the SODIMM retaining clip from the memory module socket. Grasp the latch arm intersection located on each side of the clip and gently slide the clip out. (See Figure 51.) Save the retaining clip.

---

Note Some line cards do not require a retaining clip.

---

---

Caution If the retaining clip is bent or damaged, do not attempt to fix or reuse it. This can cause serious damage to the line card. Each SODIMM replacement ships with a spare retaining clip, in case there is any damage to the existing clip.

---

Figure 51 Remove Retaining Clip from Memory Module Socket

Step 5 Remove the SODIMM by gently moving the plastic latches in an outward direction, parallel to and away from the memory module, until it releases and rotates to a 45-degree angle. (See Figure 52 and Figure 53a.)

---

Caution The plastic latch on the SODIMM socket is enclosed by the metal strain-relief latch. The plastic latch should never be moved past the metal strain-relief latch.

---

---

Caution Handle the edges of the SODIMM only. Do not touch the integrated circuit devices on the SODIMM; the metal traces, or fingers, along the edge of the SODIMM; or the pins in the SODIMM socket.

---

Figure 52 Moving the Plastic Latch Away from the SODIMM

Step 6 As the SODIMM is released, it positions itself at a 45-degree angle. Gently pull the SODIMM module out of the socket. Continue to keep the module at a 45-degree angle until it is completely removed from the socket guides. (See Figure 53b.)

Figure 53 Removing a 144-pin SODIMM Module

Step 7 Immediately place the SODIMM in an antistatic bag to protect it from ESD damage.

---

Installing a SODIMM

To install a SODIMM module, follow these steps:

---

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

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 If there is a retaining clip, check to make sure that it has not been damaged or bent. (See Figure 54.)

---

Note Some line cards do not require a retaining clip.

---

Figure 54 SODIMM Socket Retaining Clip

---

Caution If the retaining clip is damaged, do not use it. This can damage the SODIMM socket.

---

Step 4 Locate the route memory socket on the line card.

Step 5 Remove the new SODIMM from its protective antistatic bag.

---

Caution Grasp the edges of the SODIMM only. Do not touch the integrated circuit devices on the SODIMM; the metal traces, or fingers, along the edge of the SODIMM; or the pins in the SODIMM socket.

---

Step 6 Line up the SODIMM key with the key in the board socket. (See Figure 55.)

Figure 55 SODIMM with Key in Face-up Position

Step 7 The SODIMM must be lined up at a 45-degree angle. (See Figure 56a.)

---

Note When the key is in the face-up position, the metal traces on the left side of the key measure 0.9 inch (23.20 mm). The metal traces on the right side of the key measure 1.29 inches (32.80 mm). The SODIMM can not be inserted until the keys are lined up properly.

---

Step 8 Place both thumbs at the end of the socket and use your index fingers to guide the module into the socket until it is fully seated.

Be sure that your index fingers are located on the outer corners of the SODIMM to maintain even pressure when the module is being seated in the socket.

Figure 56 Inserting a 144-pin SODIMM Module

Step 9 Gently press the SODIMM down using your index fingers, distributing even pressure across the module until it locks into the tabs. (See Figure 56b.)

---

Caution Excessive pressure can damage a SODIMM socket.

---

Step 10 Verify that the release levers are flush against the side of the socket. If they are not, the SODIMM might not be seated properly.

Step 11 If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the SODIMM socket.

Step 12 If there is a retaining clip, insert it by sliding the clip between the metal strain relief and the plastic latch.
(See Figure 57.)

Figure 57 Inserting the Retaining Clip

The clip is properly installed when the clip detente protrudes below the strain relief and plastic latch. (See Figure 58.)

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.
