> Replacing Application Cards
> This chapter provides information on replacing a failed application card.
> ESD 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 an Application Card has Failed
> The system has several ways to indicate an application card failure. The first indicator is that the Status LED on the Switch Processor Card (SPC) turns red to indicate the failure of a chassis component. Another indicator is the Run/Fail LED on an application card is red or turns off if that card has a problem.
> If you see either of these indicators, you can determine the nature of the problem by using the CLI or by checking the Simple Network Management Protocol (SNMP) traps that are generated.
> Using the CLI
> Monitor application cards in the chassis by executing the following commands from the CLI in Execute mode:
> show card diag slot_#
> slot_# is the chassis slot number in which the particular card that you wish to monitor is installed. For application cards, slot_# is any integer between 1 and 16. The following is a sample output for this command to monitor the card in chassis slot 8:
> Card 8:
> Card Usable : Yes
> Card Tests : Pass
> Boot Mode : Normal
> show card info slot_#
> The following is a sample output for this command issued to monitor the card in chassis slot 8:

> If any of this 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 when conditions indicate the need to replace an application 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.
> starCardPACMigrateStart | A PAC Migration operation has begun. The first varbind identifies the PAC whose tasks are being migrated from; the second varbind identifies the PAC where the tasks are being migrated to. If a migration is taking place, it is likely that there is a problem with the original PAC.
> starCardPACMigrateComplete | A PAC Migration operation has successfully completed. The first varbind identifies the PAC whose tasks are being migrated from; the second varbind identifies the PAC where the tasks are being migrated to.
> starCardPACMigrateFailed | A PAC Migration operation has failed. The first varbind identifies the PAC whose tasks are being migrated from; the second varbind identifies the PAC where the tasks are being migrated to.
> starCardSPCSwitchoverStart | An SPC switchover operation has begun. The first varbind identifies the SPC whose tasks are being switched from; the second varbind identifies the SPC where the tasks are being switched to. If a migration is taking place, it is likely that there is a problem with the original SPC.
> starCardSPCSwitchoverComplete | An SPC Switchover has completed successfully. The starSlotNum varbind identifies the new primary SPC.
> starCardSPCSwitchoverFailed | An SPC switchover operation has failed. The first varbind identifies the SPC whose tasks are being switched from; the second varbind identifies the SPC where the tasks are being switched to.

> If any of the above traps have been generated, it is likely that the application card needs to be replaced.
> Removing the Failed Application Card
> IMPORTANT: Before you remove and replace an application card on an active system, refer to the System Administration and Configuration Reference for instructions on how to migrate or switch processes and services to a redundant (standby) card.

> 1 | Use a #2 Phillips screwdriver to loosen the screws at the top and bottom of the failed application card’s front panel.

> 2 | Lower the interlock switch on the front panel of the application 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.
> In addition, to minimize the risk of data loss, ensure that all LEDs on the PAC are completely off prior to removing the card from the chassis.

> 3 | Pull the ejector levers outward, firmly and straight, until the card is unseated from the chassis.

> 4 | Holding the card by its ejector levers, gently slide the card out of the chassis by pulling the card toward you.

> CAUTION: Do not leave chassis slots uncovered for extended periods of time. This reduces airflow through the chassis and could cause it to overheat. Make sure a card or a blanking panel is installed in every chassis slot at all times.

> 5 | Proceed to the Installing the Replacement Application Card section that follows for instructions on installing a new application card.

> IMPORTANT: If the card just removed from the chassis was an SPC, proceed to the Removing and Replacing the CompactFlash Memory Card section later in this chapter.
> Installing the Replacement Application Card

> 1 | Holding the card by its ejector levers, align the card with the upper and lower card guides of the appropriate chassis slot and 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.
> In addition, take extra caution when installing PACs. These cards contain heat sinks that could become loose or damaged if they come into contact with another card while the PAC is being inserted in the chassis slot.

> 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.

> 3 | Raise the interlock switch on the front panel of the application 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 application card’s top screw to the chassis.

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

> Removing and Replacing the CompactFlash Memory Card
> The SPC card ships with a CompactFlash memory card that stores configuration files, software images, and session capacity/feature licensing keys for the system. The following figure displays the location of the CompactFlash memory card on the SPC.
> CompactFlash Location on the SPC
> In the event of an SPC hardware failure, you must remove the CompactFlash from the failed card and install the replacement SPC. This ensures that the proper software image, configuration files, and license keys are loaded as the system boots.
> CAUTION: To reduce the risk of damage, handle the CompactFlash memory card only when necessary as part of the maintenance process.
> Removing and Replacing the CompactFlash on an SPC
> This section provides instructions for the removal of the CompactFlash card from the failed SPC and its safe insertion in the replacement SPC.

> 1 | On the failed SPC, remove the card retainer clip that secures the CompactFlash module in the socket.

> a | Lift one end of the card retainer clip up and out of the socket.

> b | Pull the card retainer clip toward you and down to completely remove it.

> 2 | Gently pull the module out of the socket.

> 3 | Repeat step 1 and step 2 to remove the module on the replacement SPC.

> 4 | Gently insert the module removed in step 1 into the socket on the replacement SPC.

> 5 | Replace the card retainer clip to secure the CompactFlash module in place.

> 6 | Proceed to the Installing the Replacement Application Card section of this chapter for instructions on installing the replacement SPC.
