Safety Information

Opening and Closing the PC

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.

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
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

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.

W

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 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.

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 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.
