Opening the System

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

CAUTION: Whenever you need to lift the system, get others to assist you. To avoid injury, do not attempt to lift the system by yourself.

1Unless you are installing a hot-plug component such as a cooling fan or power supply, turn off the system and attached peripherals, and disconnect the system from the electrical outlet and peripherals.

2If you are working with a tower system, place the system on its side on a flat stable surface with the feet overhanging the edge of the work surface.

3If present, unlock and remove the Kensington cable lock on the back of the system chassis.

4To remove the system cover, turn the latch release lock on the cover latch counterclockwise to the unlocked position. See Figure 3-4.

5Lift up on the latch on top of the system. See Figure 3-4.

6Grasp the cover on both sides and carefully lift the cover away from the system.

Closing the System

2Place the cover on top of the system and offset the cover slightly back so that it clears the chassis J hooks and lays flat on the system chassis. See Figure 3-4.

3Push the latch down to lever the cover into the closed position.

4Turn the latch release lock clockwise to the locked position. See Figure 3-4.

5Replace the Kensington cable lock on the back of the chassis. See Figure 1-4 for the location of the lock slot on the back of the chassis.
