room temperature.
• If over temperature condition still exists, go to
Action 9.
• If over temperature condition does not exist, go
to Action 10.
9. Identify the faulty
FRU. The FRUs require that you shut down the server to
perform a cold-swap.

FRU (Action 9).
• If SunVTS does not report a faulty device, go to
