> Replacing Line Cards
> This chapter provides information on replacing a failed line card.
> ESD Caution: During installation, maintenance, and/or removal, wear grounding wrist straps to avoid ESD damage to the components. Failure to do so could result in damage to electrical components and could potentially void your warranty.
> Determining Whether a Line Card has Failed
> There are several ways the chassis indicates a line card failure. The first indicator is that the Status LED on the System Management Card (SMC) turns red to indicate the failure of a chassis component. Another is that the Run/Fail LED turns red or turns off on a line card that has a problem.
> If you see either of these indicators, use the CLI or check the Simple Network Management Protocol (SNMP) traps that are generated to determine the nature of the problem.
> Using the CLI
> Enter the following commands in Execute mode from the CLI to monitor line cards:
> show card diag slot_#
> slot_# is the chassis slot number in which a particular card that you wish to monitor is installed. For line cards, slot_# would is an integer between 17 and 48. The following is a sample output for this command issued to monitor the card in chassis slot 24:
> Card 24:
> Card Usable : Yes
> Card Tests : Pass
> show card info slot_#
> Important: In ASR 5000 systems, the 10 Gigabit Ethernet Line Card is a full-height line card that takes up the upper and lower slots in the back of the chassis. Use the upper slot number only when referring to installed XGLCs in commands. Slot numbering for other installed half-height cards is maintained: 17 to 32 and 33 to 48, regardless of the number of installed XGLCs

> Card LEDs : Run/Fail: Green | Active: Green | Standby: Off
> If any of the above information appears to be erroneous such as the operational state or an LED state, check for any of the SNMP alarms listed in the Using SNMP Traps section that follows.
> Using SNMP Traps
> The system supports SNMP traps that are triggered for conditions that may indicate the need to replace a line card. The system provides the following traps:

> SNMP Trap | Description
> starCardVoltageFailure | A voltage regulation failure has been detected in a card.
> starCardBootFailed | A card has failed to start up properly. The card is not operational.
> starCardFailed | The card has failed and is no longer operational.
> starCardSWFailed | An unrecoverable software error has occurred on the card.
> starCardRCCFailed | The RCC has failed.

> Removing the Failed Line Card
> This section describes how to remove a failed line card.
> Important: Before removing and replacing a line card on an active system, refer to the System Administration and Configuration Reference for instructions on how to switch services to a redundant (standby) card.

> Step 1 | Detach any cables that are attached to the line card.

> Step 2 | Use a #2 Phillips screwdriver to loosen the screws at the top and bottom of the line card’s front panel.

> Step 3 | Lower the interlock switch on the front panel of the line card.

> Caution: To avoid damaging the card’s interlock switch, ensure that it is completely down prior to proceeding. Refer to the Product Overview Guide for additional information on the interlock switch. In addition, to minimize the risk of data loss, ensure that all LEDs on the line card are off prior to removing the card from the chassis.

> Step 4 | Pull the ejector levers outward, firmly and straight, until the card is unseated from the chassis.

> Step 5 | Holding the card by its ejector levers, gently slide the card out of the chassis.

> Caution: Do not leave chassis slots uncovered for an extended period of time. This reduces airflow through the chassis and could cause it to overheat. Make sure that there is a card or blanking panel in every chassis slot at all times.
> Installing the Replacement Line Card

> Step 1 | Hold the card by its ejector levers and align it with the upper and lower card guides of the chassis slot. Gently slide the card into the slot until the levers touch the chassis frame.

> Caution: To avoid damaging the card’s interlock switch, ensure that it is completely down prior to proceeding. Refer to the Product Overview Guide for additional information on the interlock switch.

> Step 2 | Push the ejector levers inward firmly and straight until the card is firmly seated in the chassis midplane and the ejector levers can be pushed in no further. Press firmly on the card’s faceplate to ensure that it is fully seated. The card’s front panel should be flush against the chassis’ upper and lower card mounts for the slot.

> Step 3 | Raise the interlock switch on the front panel of the line card to lock the ejector tab in place. The flange on the left-side of the interlock switch prevents movement of the ejector tab when raised completely.

> Important: The interlock switch must be fully raised in order to properly secure the line card’s top screw to the chassis.

> Step 4 | Use a #2 Phillips screwdriver to tighten the screws at the top and bottom of the line card’s front panel to secure the card to the chassis.

> Step 5 | Re-attach the cables to the line card. Refer to the following table to locate the chapter of this guide that provides information and instructions on cabling the line card.

> What to do with the Failed Line Card
> If the failed line card is still under warranty, return it to the vendor for repair.
> If the failed line card is out of warranty, contact the vendor to determine if you can send it in for repair at an additional cost.
