SFV240 suddenly shutdown

Dear Forum,

I have a SFV240 server with Solaris 10 OS. This morning i powered on my server and after few minutes powered on the server automatically shutdown and pop-up with error messages as below:

TEMP_SENSOR @ MB.T_ENC has exceeded low warning threshold.

SC Alert: TEMP_SENSOR @ MB.T_ENC has exceeded low warning threshold.
TEMP_SENSOR @ MB.T_ENC has exceeded low warning threshold.

SC Alert: System poweron is disabled.

SC Alert: Host system has shut down.


From my understanding, the above messages warned about the temperature. FYI, my room temperature is around 18 degree celcius.

Hoping for someone to help me on the above problem.

Thanks in advance.

It sounds like one of the fans went bad. The power supply is usually the problem.
