NOTE: To diagnose a problem, first find the error symptom in the left column. If directed to a check procedure, 

 replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/
 FRU listed in right column is the most likely cause.

NOTE: Normally, the processor fan should be operative, and the processor clock setting should be 

exactly set to match its speed requirement before diagnosing any processor problems.

Processor fan does not run but power supply 
fan runs.

1.  Ensure the system is not in power saving mode. See “Power 

Management” in chapter 2. 

2.  With the system power on, measure the voltage of processor fan

+12Vdc. If the reading shows normal, but the fan still does not 
work, then replace a good fan.
