NOTICE:

To disconnect a network cable, first unplug the cable from your computer and then unplug it from the

network wall jack.

3. Disconnect any telephone or telecommunication lines from the computer.

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

the system board.

In addition, take note of these safety guidelines when appropriate:

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

disconnecting 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.

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 microprocessor chip by its edges, not by its pins.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity

from your body before you touch any of your computer's electronic components, such as the microprocessor. You can do so

by touching an unpainted metal surface on the computer chassis.

As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your

body may have accumulated.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

When unpacking a static-sensitive component from its shipping carton, do not remove the component from the

antistatic packing material until you are ready to install the component in your computer. Just before unwrapping the

antistatic packaging, be sure to discharge static electricity from your body.

When transporting a sensitive component, first place it in an antistatic container or packaging.

Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
