10 Safety Instructions

Turn off the system and any devices.

Ground yourself by touching

an unpainted metal surface on the chassis before touching

anything inside the system.

While you work, periodically touch an unpainted metal surface on the chassis to dissipate any

static electricity that might harm the internal components.

Disconnect

your system and devices from their power sources. To reduce the potential of

personal injury or shock, disconnect any telecommunication lines from the system.

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 the

connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before

you connect a cable, make sure 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.

SAFETY: Protecting Against Electrostatic

Discharge

Electrostatic discharge (ESD) events can harm electronic components inside your computer.

Under certain conditions, ESD may build up on your body or an object, such as a peripheral, and

then discharge into another object, such as your computer. To prevent ESD damage, you should

discharge static electricity from your body before you interact with any of your computer’s internal

electronic components, such as a memory module. You can protect against ESD by touching a

metal grounded object (such as an unpainted metal surface on your computer’s I/O panel) before

you interact with anything electronic. When connecting a peripheral (including handheld digital

assistants) to your computer, you should always ground both yourself and the peripheral before

connecting it to the computer. In addition, as you work inside the computer, periodically touch an

I/O connector to remove any static charge your body may have accumulated.

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

• 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. Just before unwrapping the antistatic package, 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 electrostatic sensitive components in a static-safe area. If possible, use antistatic

floor pads and work bench pads.
