Replacing Application Cards


Replacing Application Cards
 
This chapter provides information on replacing a failed application 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 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 System Management Card (SMC) 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:
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
This section describes how to remove a 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.
Step 1
Step 2
 
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 packet processing card are completely off and that SMCs have stopped blinking prior to removing the card from the chassis.
Step 3
Step 4
 
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.
Step 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 SMC, proceed to the Removing and Replacing the CompactFlash Memory Card section later in this chapter.
 
Installing the Replacement Application Card
Step 1
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 packet processing cards. These cards contain heat sinks that could become loose or damaged if they come into contact with another card while the packet processing card is being inserted in the chassis slot.
 
Step 2
Step 3
 
Important: The interlock switch must be fully raised in order to properly secure the application card’s top screw to the chassis.
Step 4
Removing and Replacing the CompactFlash Memory Card
SMC cards ship 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 SMC.
 
In the event of an SMC hardware failure, you must remove the CompactFlash from the failed card and install the replacement SMC. 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 SMC
This section provides instructions for the removal of the CompactFlash card from the failed SMC and its safe insertion in the replacement SMC.
Step 1
Step 2
Step 3
Repeat step 1 and step 2 to remove the module on the replacement SMC.
Step 4
Gently insert the module removed in step 1 into the socket on the replacement SMC.
Step 5
Step 6
Proceed to the Installing the Replacement Application Card section of this chapter for instructions on installing the replacement SMC.
What to do with the Failed Application Card
If the failed application card is still under warranty, return it to the vendor for repair.
If the failed application card is out of warranty, contact the vendor to determine if it can be sent in for repair at an additional cost.
