Replacing a TRSA

This procedure section describes how to perform online replacement of a Token-Ring

ServerNet adapter (TRSA) in a Compaq NonStop™ Himalaya S-series server. You

might need to replace the TRSA if it has failed or partially failed. If POST fails and if

there is an alarm generated by the TSM package on the SAC TRSA, the TRSA must be

replaced.

Removal and replacement of the TRSA is described in the following subsections:

Note. A TRSA can be installed without shutting down the system.

Caution. If a previously installed TRSA and backplane connector have damaged pins, remove

the TRSA and install a filler panel in the vacant slot. Attach red tags to the filler panel to identify

the slot. Do not move the damaged TRSA to a different, undamaged slot. Both the TRSA and

backplane (or enclosure) must be replaced. For backplane replacement, refer to the backplane

replacement section of the Himalaya S-Series Service Provider Supplement available in

G-series Total Information Manager (TIM) collections.
