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.

Before You Begin 21

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

Information 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: Many repairs may only be done by a certified service technician. You should only perform

troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

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.

NOTICE: 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.

Disconnect any telephone or telecommunication lines from the computer.

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

If applicable, remove the computer stand (for instructions, see the documentation that came with the stand) and the cable cover, if attached (see "Cable Cover (Optional)" on page 237).

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

removing the cover.

Remove the computer cover.

• For a mini tower computer, see "Removing the Computer Cover" on page 27.

• For a desktop computer, see "Removing the Computer Cover" on page 90.

• For a small form factor computer, see "Removing the Computer Cover" on page 168.

• For an ultra small form factor computer, see "Removing the Computer Cover" on page 232.

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.

connector

To attach your computer to a network or broadband device, connect one end of a network cable to either a network jack or your network or broadband device. Connect the other end of the network cable to the network adapter connector on the back panel of your computer. A click indicates that the network cable has been securely attached.

NOTE: Do not plug a telephone cable into the network connector.

For VPro to work, the network cable must be connected to the onboard NIC.

It is recommended that you use Category 5 wiring and connectors for your network. If you must use Category 3 wiring, force the network speed to 10 Mbps to ensure reliable operation.

4 network activity light Flashes a yellow light when the computer is transmitting or receiving network
