Removing and Installing the Top 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 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 the previous chapter, a qualified service technician must do 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
1. No components in this chapter are hot swappable. Before removing the chassis cover:
Turn off and disconnect all peripheral devices and cables connected to the outside of 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.
Warning Verify that all AC Power Cords have been removed before performing any of the procedures in this
chapter.
2. If the system is mounted in a rack, release the two rack knobs and slide it 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” in the
figure.
