High-performance devices on this card can get hot during operation. To remove

the card, hold it by the faceplate and bottom edge. Allow the card to cool before

touching any other part of it or before placing it in an antistatic bag.

You can avoid bit rate errors that can cause the system to issue alarms if an alarm

threshold is exceeded by turning off the power to the online module with the

how-module subset power command before removing a transponder module.

Use the show hardware linecard command to display the status of the power to

a transponder module.

To remove a module from your unit without interrupting system operation, follow

these steps:

Remove all cables from the desired module.

Remove the module by carefully pulling it out of the slot in the motherboard.

Reinstall the blank filler module.

Place the removed module in a container appropriate for shipping and storage.

The fan assembly is hot-swappable. Fan status is reported to the processor cards.

Table 2-1

lists the status for the fan assembly. If a major alarm occurs, the fan

assembly should be replaced.

Use the show facility-alarm status command to verify it is the fan that is causing

the major alarm. If the output shows "Fan" as the source, replace the fan assembly.
