Removing and Replacing the System Unit Cover
Memory modules and video, SCSI, and ThickWire Ethernet
option modules are installed inside the system unit. Before
opening the system unit to install a module, be sure to have at
hand the antistatic wrist strap that came in the accessories kit
with your workstation.
To remove the cover from the system unit
1. If necessary, follow the instructions that came with your
worksystem software to shut down the software.
2. Turn off the system unit by pressing the 0 on the on/off
switch on the back of the unit.
3. Facing the front of the system unit, turn the cover-release
screw on the back of the unit to your right until you feel
it release. (Note that you can only loosen this screw; you
cannot remove it from the back of the system unit.)
4. Grasp each side of the cover with your hands and move the
cover straight toward you until it pulls free from the unit
as shown in Figure 4-1.
