Remove a Fan Module
You do not have to power off the controller to service the fan modules.
You should not begin this procedure unless you have a replacement fan and you are ready to install it right away.
- Extend the controller to the maintenance position.
-
To access the fan modules, open the controller fan door.
See Open the Controller Fan Door.
Caution - Close the controller fan door within 20 seconds to maintain adequate airflow to properly cool the controller. Leaving the door open for more than 20 seconds, while the controller is running, might cause the controller to overheat and shut down.
-
Identify the faulty fan module.
Each fan module has a status indicator (LED). If the LED is off, the fan is good. If the LED is lit amber, the fan has failed. The LEDs are located on the chassis mid-wall adjacent to and aligned with the fan modules, as shown in the following figure.

- Using your thumb and forefinger, grasp the fan module in the finger recesses located in the plastic between the fans.

Caution - When removing a fan module, do not rock it back and forth. Rocking a fan module can cause damage to the motherboard connectors.
-
Set the fan module aside.
Caution - Do not service any other components in the fan compartment unless the system is shut down and the power cords are removed.

Consider your next step:
-
If you removed the fan assembly as part of another procedure, return to that procedure.

Otherwise, continue to Install a Fan Module.
