Replacing Line Cards


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 24:
Slot Type : SPIO
Card Type : Switch Processing I/O Card
Card Revision : 1
Operational State : Active
Last State Change : Thursday January 27 16:28:49 EST 2000
Desired Mode : Active
Number of Ports : 2 (1000 Ethernet Dual Media)
Administrative State : Enabled
Card Lock : Locked
Halt Issued : No
Reboot Pending : No
Card Usable : Yes
Single Point of Failure : No
Attachment : 8 (Switch Processing Card)
Temperature : 20 C (limit 70 C)
Voltage: 2.5 V : 2.5 V (min 2.4 V, max 2.6 V)
Voltage: 3.3 V : 3.3 V (min 3.1 V, max 3.5 V)
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:
 
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
Step 2
Step 3
 
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
Step 5
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
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
Step 3
Important: The interlock switch must be fully raised in order to properly secure the line card’s top screw to the chassis.

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.
