Safety Instructions

Use the following safety guidelines to help protect your computer system

from potential damage and to ensure your own personal safety.

When Using Your Computer System – As you use your computer

system, observe the following safety guidelines:

Caution: Do not operate your computer system with any cover(s)

(such as computer covers, bezels, filler brackets, and

front-panel inserts) removed:

•To help avoid damaging your computer, be sure the voltage selection

switch on the power supply is set to match the alternating current

(AC) power available at your location:

– 115 volts (V)/60 hertz (Hz) in most of North and South America

and some Far Eastern countries such as Japan, South Korea,

and Taiwan

– 230 V/50 Hz in most of Europe, the Middle East, and the Far East.

Also be sure your monitor and attached peripherals are electrically

rated to operate with the AC power available in your location.

•To help avoid possible damage to the system board, wait 5 seconds

after turning off the system before removing a component from the

system board or disconnecting a peripheral device from the computer.

•To help prevent electric shock, plug the computer and peripheral

power cables into properly grounded power sources. These cables

are equipped with 3-prong plugs to ensure proper grounding. Do not

use adapter plugs or remove the grounding prong from a cable. If

you must use an extension cable, use a 3-wire cable with properly

grounded plugs.

•To help protect your computer system from sudden, transient

increases and decreases in electrical power, use a surge suppressor,

line conditioner, or uninterruptible power supply.

•Be sure nothing rests on your computer system’s cables and that the

cables are not located where they can be stepped on or tripped over.

•Do not spill food or liquids on your computer. If the computer gets

wet, consult the documentation that came with it.

vi Preface

•Do not push any objects into the openings of your computer. Doing so

can cause fire or electric shock by shorting out interior components.

•Keep your computer away from radiators and heat sources. Also, do

not block cooling vents. Avoid placing loose papers underneath your

computer; do not place your computer in a closed-in wall unit or on

a rug.

When Working Inside Your Computer –

Notice: Do not attempt to service the computer system yourself,

except as explained in this guide and elsewhere in

LSI Logic documentation. Always follow installation and

service instructions closely.

1. Turn off your computer and any peripherals.

2. Disconnect your computer and peripherals from their power sources.

Also disconnect any telephone or telecommunications lines from

the computer.

Doing so reduces the potential for personal injury or shock.

Also note these safety guidelines:

•When you disconnect a cable, pull on its connector or on its

strain-relief loop, not on the cable itself. Some cables have a

connector with locking tabs; if you are disconnecting this type of

cable, press in on the locking tabs before disconnect the cable. As

you pull connectors apart, keep them evenly aligned to avoid bending

any connector pins. Also, before you connect a cable, make sure

both connectors are correctly oriented and aligned.

•Handle components and cards with care. Don’t touch the

components or contacts on a card. Hold a card by its edges or by its

metal mounting bracket. Hold a component such as a

microprocessor chip by its edges, not by its pins.

Protecting Against Electrostatic Discharge – Static electricity can

harm delicate components inside your computer. To prevent static

damage, discharge static electricity from your body before you touch any

of your computer’s electronic components, such as the microprocessor.

You can do so by touching an unpainted metal surface, such as the metal

around the card-slot openings at the back of the computer.

Preface vii

As you continue to work inside the computer, periodically touch an

unpainted metal surface to remove any static charge your body may have

accumulated. In addition to the preceding precautions, you can also take

the following steps to prevent damage from electrostatic discharge (ESD):

•When unpacking a static-sensitive component from its shipping

carton, do not remove the component from the antistatic packing

material until you are ready to install the component in your

computer. Just before unwrapping the antistatic packaging, be sure

to discharge static electricity from your body.

•When transporting a sensitive component, first place it in an

antistatic container or packaging.

•Handle all sensitive components in a static-safe area. If possible, use

antistatic floor pads and workbench pads.
