Replacing the 296/C3 Service Access Cover
To replace the service access cover, do the following:
1. Place the service access cover on the top of the system, approximately 25 mm (1 inch) from the front
of the system.

Ensure that the fan LED cables do not get caught on the front edge of the service access cover as you
move it forward. The tabs on the service access cover slide beneath the upper chassis ledge, and the
two thumbscrews align with the screw holes on the rear of the system chassis.
3. Tighten the thumbscrews located on the rear of the cover.
4. Return the system to the operating position as described in “Returning the 296/C3 to the Operating
Position” on page 7 or “Placing the 296/E3 into the Service and Operating Position” on page 7.
