Chassis Fan
Removing the Chassis Fan
The chassis fan is mounted at the rear of the chassis.
Follow these instructions to remove the chassis fan:
1. If the server is operating, power off the server.
Refer to Chapter 1‚ Controls and Indicators for instructions.
2. Disconnect the power cord and any external cables connected to the server.
If necessary, label each one to expedite re-assembly.
3. Disconnect the chassis fan’s power connector from the system board.
Note the orientation of the fan’s power cable.
4. Remove the fan by placing a sharp flat object (screwdriver or knife) under the edge of the mounting snap
rivet.
5. Lift the snap rivet away from the surface of the rear chassis.
6. Remove the snap rivet housing from the rear of the chassis.
7. Repeat Steps 3-6 for the three remaining snap rivets.
Ensure you catch the fan when you remove the last snap rivet housing.
WARNING Before removing the cover(s), 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.
The power switch does not turn off any standby power.
Disconnect the power cord to stop or turn off standby power.
CAUTION To prevent damage from the fan if it falls, support the fan
when you release the last snap rivet and the snap rivet
housing. The fan could fall onto the system board or an
accessory board causing damage, if not supported when
released.
