Setting Up Your Computer

NOTICE: When setting up your computer, secure all cables toward the back of your work area to

prevent the cables from being pulled, tangled, or stepped on.

NOTICE: To prevent the computer from overheating and shutting down, do not place the computer in a

poorly ventilated area.

NOTE: If you have ordered a computer without a hard drive, you can install a drive by using the drive

rails that are included inside your computer (see "Installing a Hard Drive" on page 15).

Determining Placement and Orientation of the Computer

NOTICE: Do not place your monitor on top of the computer. Use a monitor stand.

NOTICE: Do not position your computer upside down.

NOTICE: In a high-vibration environment or when installing the computer under a surface or on a wall,

use the optional wall-mount bracket. To order the bracket, contact Dell. For information on contacting

Dell, see your online User’s Guide.

NOTE: To ensure proper ventilation, place the computer at least 5 cm (2 inches) from a vertical surface.

Do not place the computer in an enclosed environment without ventilation.

Installing a Device in the Module Bay

You can install a Dell™ portable device such as a floppy drive, CD/DVD drive, or second hard drive

in the module bay. Your Dell computer ships with either a CD/DVD drive or an airbay (filler blank)

installed in the module bay.

As a security feature, your computer is equipped with a module locking switch to secure a device in

the module bay. To access the switch, remove the computer cover (see "Removing the Computer

Cover" on page 16).

For added security, you may also secure a device in the module bay by using the device screw that

ships with your computer (packaged separately).
