Setting Up Your Computer

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

safety instructions in Product Information Guide.

NOTICE: If your computer has an expansion card installed (such as a modem

card), connect the appropriate cable to the card, not to the connector on the back panel.

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.

→ Help

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.

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.

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.

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

screen. See the documentation that came with your monitor for its connector locations.

Quick Reference Guide 11

Connect the speakers.

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.

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.

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.

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.

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

safety instructions located in the Product Information Guide.

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.

Light Pattern Problem Description Suggested Resolution

The computer is in a normal off condition, or a possible preBIOS failure has occurred.

The diagnostic lights are not lit after the computer successfully boots to the operating system.

A possible BIOS failure has occurred; the computer is in the recovery mode.

A possible processor failure has occurred.

Plug the computer into a working electrical outlet and press the power button.

Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer.

Configuration de votre ordinateur

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 logiciel ou l'appareil est compatible avec votre ordinateur et votre système d'exploitation.

Votre ordinateur sera correctement configuré uniquement lorsque toutes ces étapes seront réalisées. Reportez-vous aux illustrations appropriées qui suivent les instructions.

84 Guide de référence rapide

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

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.

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 pas tordre les broches du connecteur. Resserrez les vis moletées des connecteurs de câble.

REMARQUE : Sur certains moniteurs, le connecteur vidéo est placé sous

l'arrière de l'écran. Consultez la documentation fournie avec votre moniteur pour connaître les emplacements des connecteurs.

Guide de référence rapide 85

Branchez les haut-parleurs.

AVIS : Pour éviter d'endommager l'ordinateur, réglez le sélecteur de tension

manuel (si votre ordinateur dispose d'un sélecteur de tension, il se trouve à l'arrière) sur la tension la plus proche de l'alimentation disponible.

AVIS : Au Japon, le sélecteur de tension doit être placé en position 115 V même si

la tension disponible au Japon est de 100 V.

REMARQUE : Il se peut que le bloc d'alimentation de votre ordinateur ne dispose

pas d'un sélecteur de tension.

Vérifiez que le sélecteur de tension indique la tension appropriée à votre zone géographique.

Votre ordinateur est équipé d'un sélecteur de tension manuel. Les ordinateurs dotés d'un sélecteur de tension sur leur panneau arrière doivent être réglés manuellement, en fonction de la tension disponible.
