13.3 Chassis Fans

In addition to the power supply fan, the hp workstation xw4000 series uses a single rear chassis-mounted fan while the hp workstation xw6000 series uses one front chassis fan and two rear chassis-mounted CPU fans. The locations of fan power cable connectors differ between the xw4000 and the xw6000 systems.

13.3.1 Rear Chassis-Mounted Fan

To remove a rear chassis-mounted fan use the following procedure:

1.Power down the computer and disconnect the power cord from the AC outlet.

2.Remove the access panel.

✎The rest of this procedure is more easily performed with the system unit in the desktop (horizontal) position.

3.On hp workstation xw6000 systems remove the air baffle as described in section 12.2.

4.Disconnect the fan power cable(s) from the system board 1.

5.Remove the screws that secure the fan to the chassis 2.

6.Lift the fan out of the chassis 3.
