Removing the Controller Top Cover

To access internal controller components for servicing, remove the controller top cover by using the following procedure. Depending on the controller, the top cover is secured with captive screws or a release lever latch.

1. Covers with a release lever latch:
   1. If the release lever latch is in the locked position, use a Torx T15 screwdriver to turn the release lever latch clockwise to the unlocked position.
      
      
      
   2. Unlatch the top cover [1].

      Lift up on the release lever on top of the controller cover. Lifting the release lever causes the controller cover to slide toward the rear of the chassis for easy removal.

2. Covers with captive screws:
   1. Fully loosen the two captive screws at the rear of the top cover [1].
   2. Slide the top cover rearward 0.5 in (13 mm) and lift it straight up and off the chassis [2], and set the top cover aside.
