System Cooling Fan Does Not Rotate
Note
:
The system has a cooling fan module behind the hard disk drives. In
addition, there is a cooling fan that is an integral part of the power supply. There are
no serviceable components inside the power supply. If the power supply is opened,
the manufacturer's warranty is voided.
Check the following:
n
Is AC power available at the wall outlet?
n
Is the system power cord properly connected to the system and the AC wall outlet?
n
Is the power connector for the cooling fan connected to the system board?
n
Is the front panel power on indicator lit?
If the switches and connections are correct and the power outlet is functioning, the power supply
has probably failed. Contact your service representative for assistance.
