Install a Fan Module

1. Remove the replacement fan module from its packaging and place it on an antistatic mat.
2. With the fan door open, position the replacement fan module into the controller.

   The fan modules are keyed to ensure that they are installed in the correct orientation.

   
   
3. Press down on the fan module and apply firm pressure to fully seat the fan module.
4. Verify that the fan module status indicator (LED) that aligns with the replaced fan module is extinguished.
5. Close the fan door.
6. Verify that the Top Fan Fault LED on the front of the controller and the Service Required LEDs on the front and rear of the controller are extinguished.
7. Consider your next step:

   • If you installed the fan module as part of another procedure, return to that procedure.

   • Otherwise, return the controller to operation. See Returning the Controller to Operation.
