After Closing the PC

To avoid injury and equipment damage, always

follow this procedure in this order after closing the PC.

1 Reconnect the power cord.

ARNING: To reduce the risk of electrical

shock, fire, or damage to the equipment,

do not plug telecommunications or

telephone connectors into the network

interface card (NIC) (labeled as an

Ethernet connector).

2 Reconnect the modem/telephone cable, and all

other cables (such as the keyboard, mouse, and

monitor) and external devices.

3 Turn on the PC and all peripherals.

4 If you installed an add-in card, install any software

drivers supplied by the card manufacturer.

Removing the Side Panel

1 Remove the side panel by loosening the screw (D)

that secures the panel to the PC chassis.

2 Slide the panel back about 1 inch (2.5 cm), and

then lift it off the unit.

ARNING: Beware of sharp edges inside

the chassis.

Replacing the Side Panel

1 Place the side panel in the proper position on the

chassis and slide it into place.

2 Ensure that the hole for the thumbscrew aligns

with the hole in the chassis, and replace the

thumbscrew (D).

This procedure is necessary only when removing or

replacing an optical drive, memory card reader,

diskette drive, or the hard disk drive.

chassis (1).

toward the right.
