Controller Fan Module Removal and Replacement
Installing the Controller Fan Module.
1. Slide the new module into the slot and tighten the screw. The captive screw is spring-
loaded and will not tighten unless it is inserted all the way into the chassis. If the screw
keeps spinning without tightening, push on the front of the module until it snaps into
place, and then tighten the screw.
2. Check the system LEDs on the controller fan module for the following behavior:
– The green Power LED should be on and the Fan Fault LED should be off.
If the Fan Fault LED turns on or the Power LED remains off, make sure that the
controller enclosure fan module is inserted all the way into the chassis, and the
thumbscrew is tight. If the Fan Fault LED remains on, it may indicate a problem with
the new module.
3. Install the front cover. See
