Safety Information

This product has not been evaluated for connection to

an “IT” power system (an AC distribution system with

no direct connection to earth, according to

IEC 60950).

WARNING: Please read “Safety

Information” in the

arranty and Suppor

Guide before installing and connecting

your system to the electrical power

system.

Opening and Closing the PC

Preparing the PC

Before you upgrade any component in your PC, you

need to prepare the PC so that you can safely handle

it and the components.

Read the following items before attempting to upgrade

or service the PC.

• These procedures assume familiarity with the

general terminology associated with personal

computers and with the safety practices and

regulatory compliance required for using and

modifying electronic equipment.

• Write down and save the system model and

serial numbers, all installed options, and other

information about the system. It’s easier to consult

this information than to open up and examine

the PC.

• It is recommended that you use an antistatic wrist

strap and a conductive foam pad when working on

the system.

WARNING: Always disconnect the modem

cord from the telephone system, and then

disconnect the PC from the power source

before removing the front and side panels

of the PC. Failure to do so before you

open the PC or do any procedures can

result in personal injury or equipment

damage.

Before Opening the PC

1 Remove any diskette or optical disc (CD or DVD)

from the PC.

2 Click the Start button, and then click Turn Off

Computer. Click Turn Off.

3 Disconnect the modem/telephone cable, if present.

CAUTION: To reduce the risk of personal

injury from electrical shock or hot

surfaces, disconnect the power cord from

the wall outlet, and allow the internal

system components to cool before

touching.

4 Disconnect the power cord from the electrical outlet

and then from the PC.

5 Disconnect all other attached cables (such as the

keyboard, mouse, and monitor) and all external

devices.

CAUTION: Static electricity can damage

the electronic components of the PC or

optional equipment. Ensure that you are

discharged of static electricity by briefly

touching a grounded metal object.

2Upgrading and Servicing Guide

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).

Removing the Front Panel

This procedure is necessary only when removing or

replacing an optical drive, memory card reader,

diskette drive, or the hard disk drive.

1 Press and hold down the square button (1) near the

top front of the inside of the chassis. Press one tab

(2), and then press the other tab (3), toward the

outside edge of the chassis.

2 Remove the front panel.

Upgrading and Servicing Guide 3

Replacing the Front Panel

1 Align the top of the front panel with the top of the

chassis front.

2 Press the panel onto the chassis at the top and at

each side near the bottom until the panel snaps into

place.

Removing and Replacing

Drives

Your PC has several drives that you can replace or

upgrade. See the preceding topic, “Locating

Components Inside the PC,“ for drive type and

location.

The hard disk drive is either a Serial ATA (advanced

technology attachment) drive that uses a narrow data

cable, or a Parallel ATA drive that uses a wide data

cable.

Select models have a second hard disk drive.

CAUTION: Back up your personal files on

the hard disk drive to an external

storage device, such as a CD, before

removing the hard disk drive. Failure to

do so will result in data loss. After

replacing the hard disk drive, you need

to run System Recovery using the

recovery discs to load the factory-

installed files. See the user

documentation that came with your PC

for details about the recovery procedure.

You can add an optical drive into an empty lower

optical drive bay.

IMPORTANT: Before adding a new optical drive,

make sure that it is compatible with the Microsoft®

Windows®XP operating system. Also, make sure you

have the correct software and drivers for the optical

drive to work with the operating system.

4Upgrading and Servicing Guide

Removing a Drive

1 Complete the procedures to prepare the PC, to

remove the side panel, and to remove the front

panel. See “Opening and Closing the PC“ on

page 1.

2 Locate the drive you want to remove.

3 Release the drive from the chassis by lifting the

tab (1) on the latch drive bracket, and then sliding

(2) the drive partway out of the bay. (The latch

drive bracket secures the drives in their respective

positions in the chassis.)

For a second hard disk drive, remove the two

screws (3) and then slide the drive part way back

out of the bay (4).

Removing the Second Hard Disk Drive

4 Disconnect the power cable and data cable from

the back of the drive you want to remove, as

indicated in the following illustrations:

• For optical drives, disconnect the power cable

(P) and the data cable (D) from the back of the

drive you want to remove. If the drive has a

sound cable (S), disconnect it also.

• For most drive cables, use a gentle rocking

motion to free the plug. For Serial ATA hard disk

drive cables, press the latch (5) (select models

only) in the center of each plug and pull the plug

(6) from the drive connector.

5 Pull the drive out of the drive bay.

6 If you are replacing the old drive with a new drive,

remove the four guide screws (two on each side)

from the old drive. You need these screws to install

the new drive.

Replacing or Adding a Drive

1 If necessary, remove the existing drive. See

“Removing a Drive“ on page 4.

2 If you are adding a drive to an empty lower optical

drive bay, you must remove the blank plate from

the bay. To do so, insert a flat screwdriver into the

blank plate slot (C) and rotate the screwdriver to

break the blank plate out of the chassis. Discard the

blank plate.

3 Make sure the jumper on the new optical drive or

new Parallel ATA hard disk drive is in the CS

(Cable Select) position. Your drive may vary from

the illustration. The Serial ATA hard disk drive does

not use Cable Select.

Cable Select Jumper

4 Install four guide screws on the sides of the new

drive (two on each side). The screws help guide the

drive into its proper position in the bay.

For a second hard disk drive, skip this step and go

to step 5.

5 Slide the drive part way into the drive bay, making

sure to align the guide screws with the guide slots.

6Upgrading and Servicing Guide

For a second hard disk drive, slide the drive into

the bay (with connectors facing out) and align the

screw holes (3). Insert the two screws (4).

6 Reconnect the power and data cables to your drive

as indicated in the following illustrations. If it is

present, reconnect the sound cable.
