Removing and Installing the Top Cover
WARNING
Make sure that the rack is anchored securely so it will not tilt
forward when the server chassis is extended. A crush hazard exists
should the rack tilt forward.
CAUTION
Do not leave the chassis cover open or a system fan removed any longer
than necessary; system cooling could be reduced. Do not operate the
server with the cover removed.
Removing the Top Cover
To remove the top cover, refer to Figure 53 and follow these instructions:
1. Observe the safety and ESD precautions described in Warnings and Cautions and in Before
Top Cover or Module Removal on page 121.
2. If the chassis is rack-mounted, slide the chassis out far enough to expose the back area of
the top cover (see cautions and warnings above).
3. To open the top cover, use a screwdriver or a coin to turn the locking mechanism to the
unlocked position.
4. Push the top cover towards the back of the system until it stops, approximately 1-inch
towards the rear.
5. Lift the cover up from the front and remove it from the chassis.
