Removing and Installing the Chassis Cover
Warning Make sure the rack is anchored securely so it does not tilt forward when the server is extended. A
crush hazard exists if the rack tilts forward. This could cause serious injury.
Caution
 For proper cooling and airflow, do not operate the server for more than three minutes with the
cover removed. Do not leave the chassis cover open or a system fan removed any longer than
necessary; system cooling could be reduced.
 The server comes with a removable top cover that allows the
PCIe cards, memory risers, and
the system fans to be hot swapped, and other system components to be serviced. Except for
components described in this chapter, a qualified service technician must perform all servicing.
 Provide electrostatic discharge (ESD) protection by wearing an antistatic wrist strap attached to
chassis ground of the system-any unpainted metal surface-when handling components.
Removing the Top Cover
Before removing the top cover, observe these safety guidelines:
1. If you are not replacing a hot swap component:
Turn off and disconnect all peripheral devices connected to the server.
Power down the system by pressing and holding the power button on the front of the chassis for several
seconds.
After the server shuts down, unplug all AC power cords to remove standby power from the system.
2. If the system is mounted in a rack, release the two captive screws and slide the system out far enough to
expose the entire top cover.
3. Remove the one screw in the top cover. See letter “A” in the figure below.
4. Press down on the two latch buttons on the top cover and slide the top cover off the latches. See letter “B” in
the figure below.
5. Slide the top cover toward the rear until it stops, and then lift the cover to remove it. See letter “C” below.
