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.There are several ways the chassis indicates a line 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 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 he Simple Network Management Protocol (SNMP) traps that are generated to determine the nature of the problem.
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:
show card info slot_#
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.
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:
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.|

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.

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. |

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.

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.

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.|

|
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.

If the failed line card is still under warranty, return it to the vendor for repair. Starent Network’s contact information is located in the About This Guide chapter of this document.
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.
If you choose to discard the failed component, please return it to Starent Networks for proper disposal. Contact us at: recycle@starentnetworks.com to obtain return instructions. Starent Networks will pre-pay or reimburse shipping charges associated with this service.
