Removing the System Access Cover

Installing the Access Cover

You need to remove the system access cover, and in some cases the front bezel, to reach
components inside the system. Facing the front of the system, the access cover is on the
right side for pedestal-mounted (tower) servers, and on the top for rack-mounted
servers.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Turn off all peripheral devices connected to the system.
3. If you have not already done so, turn off the system by using the power on/off
switch on the front panel AND unplug all AC power cords.
4. Label and disconnect all peripheral cables attached to the I/O panel on the back of
the system.
5. Remove and save the three screws from the back of the access cover; you will need
them later to reattach the cover.
Be sure the chassis key lock on the front of the system is in the unlocked

position. Otherwise, you will be unable to remove the cover. The chassis keys are not
all the same, you cannot use one key to open multiple units.
6. Place the fingertips of your right hand under the built-in handle on the back of the
cover. A rounded, rectangular depression in the front middle of the access cover
serves as another handle.
7. Using an even pull, slide the cover backward, about an inch, until it stops.
8. Pull the entire cover outward, straight away from the chassis, to disengage the tabs
from the notches in the top and bottom edges of the chassis. Set the cover aside.
1. Before replacing the access cover, check that you have not left loose tools or parts
inside the system.
2. Check that cables, PCI option boards, and other components are properly installed.
3. Position the cover over the chassis so that the rows of tabs align with slots in the
chassis. Slide the cover toward the front of the system until the tabs on the cover
firmly engage in the chassis.
4. Attach the cover to the chassis with the three screws you removed earlier, and
tighten them firmly (6.0 inch-pounds).
