ML370 G4 Shuts down due to Secondary Fan failure

We recently installed a redundant Fan and approx. 12 hours later, the Fan failed and the server subsequently shut down.

Doesanyone know why this would happen? The OS is SCO 5.0.6

Here is an output of the syslog:
WARNING: casm: System Fans Not Redundant (Location CPU)

WARNING: casm: Fan Failure (Fan 4, Location CPU)

Re: ML370 G4 Shuts down due to Secondary Fan failure

was the fan new or used?
fans don't go bad too often, but it doesn't mean they never go bad.
Just change it with a good fan...

Thanks for replying but I believe my question pertains to "why does a redundant fan failure cause a system running SCO 5.0.6 to shut down?

The fans are all new.

Hi

The reasons can be

the server maybe over heating
if you have the insight manager agents installed that might monitoring the temperature
If the fan itself is not faulty then there might be some hardware issue which triggers a shutdown.
The best would be to open a case with HP miht be you will be required to run a hardware diagnostics to check if the hardware is not having any issues.

The server was not overheating prior to the addition of the redundant Fan kit.
