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 your user documentation

before installing and connecting your

computer 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 PC model and serial

numbers, all installed options, and other

information about the computer. It is easier to

consult the information in this guide than to open

and examine the PC.

• We recommend that you use an antistatic wrist

strap and a conductive foam pad when working

inside the PC.

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 (floppy disk), memory card

media, or optical disc (CD or DVD) from the PC.

The PC power must be on to remove discs.

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 you

touch them.

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.

CAUTION: 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.

Removing and

Replacing Drives

Your PC has several drives that you can replace or

upgrade. You can add a drive into an empty drive

bay. See the preceding topic, “Locating Components

Inside the PC,” for drive type and location. For hard

disk drives, see “Removing a Hard Disk Drive“ on

page 5.

IMPORTANT: Before adding a new diskette drive,

memory card reader, optical drive, or hard disk 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 drive to

work with the operating system.

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 Disconnect the power cable (1) and data cable (2)

from the back of the drive you want to remove, as

indicated in the following illustrations. Use a gentle

rocking motion. Some units may have a sound

cable. If so, disconnect the sound cable (3).

Inside the PC“ on page 3. The other two slots in the

hard disk drive cage are for secondary hard disk

drives (select models).

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.

6Upgrading and Servicing Guide

CAUTION: Back up your personal files on

the hard disk drive to an external storage

device, such as a CD, before removing the
