Chassis Fan
The chassis fan is mounted within the side panel of the chassis.
WARNING Before opening the HP Server, always disconnect the power cords and unplug telephone
cables. Disconnect the power cords to avoid exposure to high energy levels that may
cause burns when parts are short-circuited by metal objects, such as tools or jewelry.
Disconnect telephone cables to avoid exposure to shock hazard from telephone ringing
voltages.
Note that the power switch does not turn off the standby power. Disconnect the power
cord to turn off standby power.
Use the following steps to replace the chassis fan:
1. If the server is operating, log off all users, back up files, and power down the server.
2. Disconnect the power cord and any external cables connected to the server. If necessary, label each one
to expedite re-assembly.
3. Open the side panel.
4. If necessary, remove any accessory boards from the system board allowing clear access to the fan.
