System troubleshooting
Trouble symptom
Action
The system boots, the fans turn at high speed
but do not return to normal speed. The system
is extremely noisy.
Two possible causes are:
•
One or more fans are faulty and you need
to replace the fan module. For instructions,
see the 600r Server Maintenance and
Diagnostics Guide (NN44200-703).
•
Reflash the system board F/W with
Nortel-approved BMC and FRU/SDR and
try again.
If neither of the above actions resolves the
problem, replace the server.
The system boots and beeps, but there is no
video. (In some cases a red LED appears on
the front cover).
