the guidelines below when installing your computer in an enclosure.

NOTICE: The operating temperature specified in this manual reflects the maximum

ambient operating temperature. The ambient room temperature must be

a consideration when installing your computer in an enclosure. For details about

your computer’s specifications, see "Specifications" in your User’s Guide.

10 Quick Reference Guide

Leave 10.2 cm (4 in) minimum clearance on all vented sides of the computer

to permit the airflow required for proper ventilation.

If your computer is installed in a corner on or under a desk, leave 5.1 cm

(2 in) minimum clearance from the back of the computer to the wall to

permit the airflow required for proper ventilation.

If your enclosure has doors, ensure that they allow at least 30 percent airflow

through the enclosure (front and back).

Quick Reference Guide 11

12 Quick Reference Guide

Transferring Information to a New Computer

You can use your operating system wizards to help you transfer files and other

data from one computer to another computer.

Microsoft Windows XP

The Microsoft

Windows XP operating system provides the Files and Settings

Transfer Wizard to transfer data, such as:

E-mail messages

Toolbar settings

•Window sizes

Internet bookmarks

You can transfer data from one computer to another computer over a network

or serial connection, or by storing the data on removable media, such as

a writable CD or DVD.

NOTE: You can transfer information from one computer to another computer by

directly connecting a serial cable to the input/output (I/O) ports of the two computers. To

transfer data over a serial connection, you must use the Network Connections

utility in the Control Panel to perform additional configuration steps, such as setting

up an advanced connection and designating the host computer and the guest computer.

For instructions on setting up a direct cable connection between two computers,

see Microsoft Knowledge Base Article #305621, titled How to Set Up a Direct Cable

Connection Between Two Computers in Windows XP. This information may not be

available in certain countries.

Using the Files and Settings Transfer Wizard requires the Operating System

disc that came with your computer or a wizard disk, which the wizard can

create for you.

NOTE: For more information about transferring data, search support.dell.com for

document #154781 (What Are The Different Methods To Transfer Files From My Old

Computer To My New Dell™ Computer Using the Microsoft Windows XP Operating

System?).

NOTE: Access to the Dell Knowledge Base document may not be available in

certain countries.

Quick Reference Guide 13

Power Protection Devices

Several devices are available to protect against power fluctuations and failures:

Surge protectors

Line conditioners

Uninterruptible power supplies (UPS)

16 Quick Reference Guide

Surge Protectors

Surge protectors and power strips equipped with surge protection help prevent

damage to your computer from voltage spikes that can occur during electrical

storms or after power interruptions. Some surge protector manufacturers include

warranty coverage for certain types of damage. Carefully read the device warranty

when choosing a surge protector and compare joule ratings to determine the

relative effectiveness of different devices. A device with a higher joule rating

offers more protection.

NOTICE: Most surge protectors do not protect against power fluctuations or

power interruptions caused by nearby lightning strikes. When lightning occurs in

your area, disconnect the telephone line from the telephone wall jack and

disconnect your computer from the electrical outlet.

Many surge protectors have a telephone jack for modem protection. See the

surge protector documentation for modem connection instructions.

NOTICE: Not all surge protectors offer network adapter protection. Disconnect the

network cable from the network wall jack during electrical storms.

Line Conditioners

NOTICE: Line conditioners do not protect against power interruptions.

Line conditioners are designed to maintain AC voltage at a fairly constant level.

Uninterruptible Power Supplies

NOTICE: Loss of power while data is being saved to the hard drive may result in

data loss or file damage.

NOTE: To ensure maximum battery operating time, connect only your computer to

a UPS. Connect other devices, such as a printer, to a separate power strip that

provides surge protection.

A UPS protects against power fluctuations and interruptions. UPS devices contain

a battery that provides temporary power to connected devices when AC power

is interrupted. The battery charges while AC power is available. See the UPS

manufacturer documentation for information on battery operating time and to

ensure that the device is approved by Underwriters Laboratories (UL).
