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 beginning of the

User’s Guide before installing and

connecting your system to the electrical

power system.

The Upgrading and Servicing Guide provides

instructions on how to remove and replace hardware

components of your PC.

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 will be easier to

consult this information than to open up and

examine the PC.

• HP recommends that you use an antistatic wrist

strap and a conductive foam pad when working on

the system.

WARNING: Always disconnect the modem

cable 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

To avoid injury and equipment damage, always

follow this procedure in this order 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.

WARNING: To reduce the risk of personal

injury from electrical shock or hot

surfaces, disconnect the power cable from

the wall socket, and allow the internal

system components to cool before

touching.

4 Disconnect the power cable 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.

2upgrading and servicing guide

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.

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 cable.

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 attached 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
