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:
T
Is AC power available at the wall outlet?
T
Is the system power cord properly connected to the system and the
AC wall outlet?
T
Is the power connector for the cooling fan connected to the system
board?
T
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.
