xInstalling Options in Your Personal Computer

Identifying Your Computer
In most instances, the best way to identify your computer is by the model/type
number. The model/type number indicates the various features of the computer,
such as the type of microprocessor or whether the computer is a desktop or
minitower. You can find this number on the small label on the front of your
computer. An example of a model/type number is 6282-54A.
Throughout this book, however, your computer is identified by the number of drive
bays offered with these models. If your computer has three drive bays, it is referred
to as the 3-bay design. If your computer has four drive bays, it is referred as the
4-bay design. These following naming conventions are used only where it is
appropriate. Instructions without these naming conventions apply to all computer
models.
3-Bay Design
With the cover on, bay 2 in the 3-bay design is not visible. This bay is intended for
a hard disk drive, which does not have accessible media such as a CD-ROM drive
or diskette drive. The 3-bay design has two expansion slots for adapters, as shown
in the rear view below.

4-Bay Design
With the cover on, bay 4 in the 4-bay design is not visible. This bay is intended for
a hard disk drive, which does not have accessible media such as a CD-ROM drive
or diskette drive. The 4-bay design has four expansion slots for adapters, as shown
in the rear view below.

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 and
features 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
discussed in this book. Also, important information about required tools, electrical
safety, and static-sensitive devices is discussed.
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.

2Installing Options in Your Personal Computer

Electrical Safety
CAUTION:
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.
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.
Chapter 1. Overview 3

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 2. Preparing to Install and Remove Options
This chapter provides instructions for locating the options you want to install or
remove.
Disconnecting Cables and Removing the Cover
Before you begin
Read “Electrical Safety” on page 3 and “Handling Static-Sensitive Devices”
on page 4.
Remove any media (diskettes, compact discs, or tapes) from the drives, and
then turn off all attached devices and the computer. For more information
on removing media, see Using Your Personal Computer.
1For models equipped with a cover lock, make sure it is unlocked.
2Disconnect all cables attached to the computer; this includes power cords,
cables or lines connected to the input/output (I/O) ports.
3Remove the cover screw from the rear of the computer. Slide the cover
approximately 19 mm (0.75 in.) toward the front of the computer, and lift it
off. The following illustration shows the cover being removed from a 4-bay
design.
Cover Screw
Note: Although your computer might differ from the one shown above, the
removal of the cover works the same for the different computer
models.
