→

→ Help

NOTICE: To help allow the computer to maintain proper operating temperature,

ensure that you do not place the computer too close to a wall or other storage
compartment that might prevent air circulation around the chassis.

NOTE: Before you install any devices or software that did not ship with your

computer, read the documentation that came with the device or software, or
contact the vendor to verify that the device or software is compatible with your
computer and operating system.

10 Quick Reference Guide

You must complete all the steps to properly set up your computer. See the
appropriate figures that follow the instructions.

NOTICE: Do not attempt to operate a PS/2 mouse and a USB mouse

simultaneously.

1

Connect the keyboard and mouse.

NOTICE: Do not connect a telephone line to the network adapter connector.

Voltage from telephone communications can cause damage to the network adapter.

2

Connect the telephone line or network cable.

Insert the network cable, not the telephone line, into the network
connector. If you have an optional modem, connect the telephone line to
the modem.

3

Connect the monitor using ONLY ONE of the following cables: the white
DVI cable or the blue VGA cable (do not connect both cables to the same
computer).

Align and gently insert the monitor cable to avoid bending connector pins.
Tighten the thumbscrews on the cable connectors.

NOTE: Some monitors have the video connector underneath the back of the

NOTICE: To avoid damaging your computer, set the manual voltage-selection

switch (on the back of the computer, if your computer has a voltage selection
switch) for the voltage that most closely matches the AC power available in your
location.

NOTICE: In Japan, the voltage selection switch must be set to the 115-V position

even though the AC power available in Japan is 100 V.

NOTE: Your computer’s power supply may or may not have a voltage selection

switch.

5

Verify that the voltage selection switch is set correctly for your location.

Your computer has a manual voltage-selection switch. Computers with a
voltage selection switch on the back panel must be manually set to operate
at the correct operating voltage.

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from
potential damage and to help ensure your own personal safety.

CAUTION: Before you begin any of the procedures in this section, follow the

safety instructions in the Product Information Guide.

Start

32 Quick Reference Guide

CAUTION: Handle components and cards with care. Do not 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 processor by its edges, not by its pins.

NOTICE: Only a certified service technician should perform repairs on your

computer. Damage due to servicing that is not authorized by Dell is not covered by
your warranty.

NOTICE: 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 you
disconnect the cable. As you pull connectors apart, keep them evenly aligned to
avoid bending any connector pins. Also, before you connect a cable, ensure that
both connectors are correctly oriented and aligned.

To avoid damaging the computer, perform the following steps before you
begin working inside the computer.

1

Turn off your computer.

NOTICE: To disconnect a network cable, first unplug the cable from your computer

and then unplug it from the network wall jack.

2

Disconnect any telephone or telecommunication lines from the computer.

3

Disconnect your computer and all attached devices from their electrical
outlets, and then press the power button to ground the system board.

4

If applicable, remove the computer stand (for instructions, see the
documentation that came with the stand).

CAUTION: To guard against electrical shock, always unplug your computer from

the electrical outlet before removing the cover.

5

Remove the computer cover:

• Remove the mini tower computer cover (see "Mini Tower Computer"
on page 34).

• Remove the desktop computer cover (see "Desktop Computer" on
page 36).

• Remove the small form factor computer cover (see "Small Form
Factor Computer" on page 38).

NOTICE: Before touching anything inside your computer, ground yourself by

touching an unpainted metal surface, such as the metal at the back of the computer.
While you work, periodically touch an unpainted metal surface to dissipate any
static electricity that could harm internal components.

Quick Reference Guide 55

To help you troubleshoot a problem, your computer has four lights labeled
"1," "2," "3," and "4" on the front panel. The lights can be off or green. When
the computer starts normally, the patterns or codes on the lights change as
the boot process completes. If the POST portion of system boot completes
successfully, all four lights display solid green. If the computer malfunctions
during the POST process, the pattern displayed on the LEDs may help
identify where in the process the computer halted.

NOTE: The orientation of the diagnostic lights may vary depending on the system

type. The diagnostic lights can appear either vertical or horizontal.

use System Restore (see "Restoring Your Operating System" on page 61 for
more information) to return your operating system to the operating state it
was in before you installed the new device driver.

PRÉCAUTION : Avant de commencer toute procédure de cette section, lisez les

consignes de sécurité du Guide d'information sur le produit.

AVIS : Si votre ordinateur est doté d'une carte d'extension (une carte modem par

exemple), branchez le câble approprié sur la carte et non pas sur le connecteur du
panneau arrière.

AVIS : Pour garantir une bonne température de fonctionnement de l'ordinateur,

.

veillez à ne pas placer l'ordinateur trop près d'un mur ou d'un compartiment de
rangement pouvant empêcher une bonne circulation de l'air autour du châssis.

REMARQUE : Avant d'installer tout périphérique ou logiciel qui n'a pas été livré

avec votre ordinateur, lisez attentivement la documentation fournie avec le logiciel
ou le périphérique ou contactez votre fournisseur, afin de vous assurer que le

AVIS : N'utilisez pas simultanément une souris PS/2 et une souris USB.

1

Branchez le clavier et la souris.

AVIS : Ne branchez pas de ligne téléphonique dans le connecteur d'adaptateur

réseau. En effet, la tension des communications téléphoniques risquerait de
l'endommager.

2

Branchez la ligne téléphonique ou le câble réseau.
Insérez le câble réseau, et non la ligne téléphonique, dans le connecteur

réseau. Si vous disposez d'un modem optionnel, connectez la ligne
téléphonique à ce dernier.

Connectez le moniteur UNIQUEMENT à l'aide de l'un des câbles
suivants : le câble DVI blanc ou le câble VGA bleu (ne connectez pas ces
deux câbles au même ordinateur).

Alignez, puis insérez avec précaution le câble du moniteur de manière à ne
