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

Preparing for Installation
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.

•Removing an EPA from the Modular Gigabit Ethernet Line Card
•Inserting an EPA into a Modular Gigabit Ethernet Line Card
Figure 6 shows an exploded mechanical view of a Gigabit Ethernet EPA with three line card SFP receptacles, an SFP module, and a duplex LC-type cable.
Figure 6 Removing and Replacing EPAs
Removing an EPA from the Modular Gigabit Ethernet Line Card
You can remove an EPA from the Modular Gigabit Ethernet line card with or without the SFP modules installed.
To remove an EPA from your Modular Gigabit Ethernet line card, use Figure 7 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its directions for use.
Step 2 Disconnect the LC-type fiber-optic cable connector from the SFP module.
Note which cable connector plug is TX and which is RX for reattachment.
Step 3 Insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.
Step 4 Remove the Modular Gigabit Ethernet line card from the chassis, as described in the "Removing a Line Card" section, and place the line card on a clean, flat surface.
Step 5 Use a Phillips screwdriver to loosen and unscrew the two screws that connect the EPA to the line card, located on the faceplate of the line card, as shown in Figure 7A.
Step 6 Use a Phillips screwdriver to loosen and unscrew the one screw that connects the EPA to the inside of the line card, as shown in Figure 7B.
Step 7 Gently lift up on one corner of the EPA to disconnect the EPA from the line card, as shown in Figure 7C.
Caution To prevent ESD damage, handle EPAs by the card carrier edges only.
Caution Avoid touching the EPA printed circuit board, components, or any connector pins.
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.

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
