FIGURE 3-7
Detecting a Faulty Fan Module
3.3.4 Removing a Fan Module
Caution –
Hazardous moving parts. Unless the power to the server is completely
shut down, the only service permitted in the fan compartment is the replacement of
the fan modules by trained personnel.
1. Extend the server into the maintenance position.
See Section 2.6, “Extending the Server to the Maintenance Position” on page 2-6 .
2. Unlatch the fan module door.
Pull the release tabs back to release the door. Open the top cover toward the rear
of the server.
Note – Close the top cover door immediately after replacing the fan to maintain
airflow in the server. Leaving the door open for more than 60 seconds while the
server is running might cause the server to overheat and shut down.
3. Identify the faulty fan module with a corresponding Service Required LED.
The Fan Fault LEDs are located on the fan board.
4. Using thumb and forefinger in between the two fans, pull the fan module up
and out of the connector.
