4-4 Installing Options
System Unit Covers
The following sections describe how to remove and replace the system
cover and the front panel. Remove the system cover to access the interior
of the system (see “Removing the Cover,” next).
Remove the front panel to install or replace a 3 1/2-inch accessible device,
a 5 1/4-inch accessible device, or a 3 1/2-inch internal device (see
“Removing the Front Panel” later in this section).
Removing the Cover
Remove the cover as follows.
Before removing the cover, turn off system
power and unplug the system power cable. Power is removed only when
the power cable is unplugged.
1.
Turn off the system and any peripherals, and unplug the system
power cord.
2.
Disconnect any external options (such as a keyboard and monitor)
from the front or rear of the system unit.
Electrostatic discharge can damage computer
components. Discharge static electricity by touching a metal object before
removing the cover.
3.
If the system unit is in the minitower configuration, place it on its
right side (the side with four rubber feet).
4.
If you have a padlock in the locking tab on the rear of the chassis,
remove it.
