System Cooling Fans Do Not Rotate
Note: The system has five hot-swap cooling fan
modules. In addition, their are two cooling fans that
are an integral part of each power supply. There are no
serviceable components inside the power supply. If the
power supply is opened, the manufacturer's warranty is
voided. Three of the hot-swap fans are accessible from
the rear of the system. The other two hot-swap cooling
fans are accessible from the front of the system by
removing the left hand bezel (refer to the Upgrades
and Options chapter 5 in this guide.)
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.
