xii Installing Options in Your Personal Computer

Chapter 1. Overview
Adding hardware options to your computer is an easy way to increase its
capabilities. Instructions for removing, installing, and replacing options are
included in this book. When adding an option, use these instructions along with
the instructions that come with the option. If you have installed options before, you
might be able to perform some activities without detailed instructions.
This chapter provides a brief introduction to the options and features that are
available for your computer. Also, important information about required tools,
electrical safety, and static-sensitive devices is included.
Important
Before you install or remove any option, read the safety procedures and
component-handling guidelines in this chapter. These precautions and
guidelines will help you work safely.
Refer to Using Your Personal Computer for general information on the use, operation,
and maintenance of your computer. Using Your Personal Computer also contains
information to help you solve problems and get repair service or other technical
assistance.

Chapter 1. Overview 3

Electrical Safety
Warning: Electrical current from power, telephone, and communication cables can
be hazardous. To avoid any shock hazard, disconnect all power cords and cables as
described in the following information.
The presence of 5 V standby power might result in damage to your hardware unless
you disconnect the power cord from the electrical outlet before opening the
computer.
For your safety, always do the following before removing the cover:
1. Shut down all programs as described in your operating-system documentation.
2. Turn off the computer and any attached devices, such as printers, monitors, and
external drives.
Note: Personal computer users in the United Kingdom who have a modem or
fax machine attached to their computer must disconnect the telephone
line from the computer before unplugging any power cords (also known
as power cables). When the computer is reassembled, users must
reconnect the telephone line after plugging in the power cords.
3. Unplug all power cords from electrical outlets.
4. Disconnect all communication cables from external receptacles.
5. Disconnect all cables and power cords from the back of the computer.
Note: Do not reconnect any cables or power cords until you reassemble the
computer and put the cover back on.
CAUTION:
Never remove the cover on the power supply. If you have a problem with the
power supply, have your computer serviced.
4Installing Options in Your Personal Computer

Handling Static-Sensitive Devices
Have you ever walked across a carpeted floor, then touched an object and received
a small electrical shock? That's static electricity, and although harmless to you, it
can seriously damage computer components and options.
Important
When you add an option, do not open the static-protective package containing
the option until you are instructed to do so.
When you handle options and other computer components, take these precautions
to avoid static electricity damage:
Limit your movement. Movement can cause static electricity to build up around
you.
Always handle components carefully. Handle adapters and memory-modules
by the edges. Never touch any exposed circuitry.
Prevent others from touching components.
When you are installing a new option, touch the static-protective package
containing the option to a metal expansion-slot cover or other unpainted metal
surface on the computer for at least two seconds. This reduces static electricity
in the package and your body.
When possible, remove the option and install it directly in the computer without
setting the option down. When this is not possible, place the static-protective
package that the option came in on a smooth, level surface and place the option
on it.
Do not place the option on the computer cover or other metal surface.
Chapter 1. Overview 5

Chapter 2. Preparing to Install and Remove Options
This chapter provides instructions for accessing and locating the options you want
to install or remove.
Disconnecting Cables and Removing the Side Cover
Before you begin
Read “Electrical Safety” on page 4 and “Handling Static-Sensitive Devices”
on page 5.
Remove any media (diskettes, compact discs, or tapes) from the drives, and
then turn off all attached devices and the computer.
Warning: The presence of 5 V standby power might result in damage to your
hardware unless you disconnect the power cord from the electrical outlet before
opening the computer.
1Unplug all power cords from electrical outlets.
2If you have a modem or fax machine attached to your computer, disconnect
the telephone line from the wall outlet and the computer.
3Disconnect all cables attached to the computer; this includes power cords,
input/output (I/O) cables, and any other cables connected to the computer.
