System Cooling Fan Does Not Rotate

Problem Solving
Note: The system has a cooling fan module behind the
hard disk drives. In addition, their 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:
Is AC power available at the wall outlet?
Is the system power cord properly connected to the
system and the AC wall outlet?
Is the power connector for the cooling fan connected
to the system board?
Is the front panel power on indicator lit?
Is the cable from the front panel board connected to
the system board?
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.
