Removing the Cover

Before installing optional hardware inside your system, you must first remove the cover from the system unit.

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 and unplug the system unit.

2.Disconnect any external devices (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 upright (minitower) position, 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.

5.Remove the two thumbscrews holding the cover to the rear of the chassis.
