device, a cable is connected between the audio line-out

connector of the device and the audio line-in connector of the

computer.

Audio line-out connector Used to send audio signals from the computer to external

devices, such as powered stereo speakers (speakers with

built-in amplifiers), headphones, multimedia keyboards, or the

audio line-in connector on a stereo system or other external

recording devices.

Ethernet connector Used to attach an Ethernet cable for a local area network

(LAN).

Note: To operate the computer within FCC Class B limits, use

a Category 5 Ethernet cable.

Microphone connector Used to attach a microphone to your computer when you want

to record sound or if you use speech-recognition software. This

connector might be located on the front of the computer.

Chapter 2. Installing options and replacing hardware

This chapter provides instructions for installing options and replacing hardware for

your computer. You can expand the capabilities of your computer by adding

memory modules, adapter cards, or drives. When installing or replacing an option,

use these instructions along with the instructions that come with the option.

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the

defective part has been removed from the computer and you are ready to install

the new part. Static electricity, although harmless to you, can seriously damage

computer components and parts.

When you handle parts and other computer components, take these precautions to

avoid static-electricity damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always handle parts and other computer components carefully. Handle adapter

cards, memory modules, system boards, and microprocessors by the edges.

Never touch any exposed circuitry.

v Prevent others from touching the parts and other computer components.

v Before you replace a new part, touch the static-protective package containing the

part to a metal expansion-slot cover or other unpainted metal surface on the

computer for at least two seconds. This reduces static electricity in the package

and your body.

v When possible, remove the new part from the static-protective packaging, and

install it directly in the computer without setting the part down. When this is

not possible, place the static-protective package that the part came in on a

smooth, level surface and place the part on it.

v Do not place the part on the computer cover or other metal surface.

Installing options and replacing hardware

This section provides introductions for installing options and replacing hardware

for your computer. When installing or replacing an option, use these instructions

along with the instructions that come with the option.

Attention

Do not open your computer or attempt any repair before reading and understanding the

“Important safety information” in the ThinkCentre Safety and Warranty Guide that came with

your computer. To obtain a copy of the ThinkCentre Safety and Warranty Guide, go to:

http://www.lenovo.com/support

Note: Use only computer parts provided by Lenovo.

Installing external options

External speakers, a printer, or a scanner can be connected to your computer. For

some external options, you must install additional software in addition to making

the physical connection. When installing an external option, see “Locating

connectors on the front of your computer” on page 6 and “Locating connectors on

the rear of your computer” on page 7 to identify the required connector, and then

use the instructions that come with the option to help you make the connection

and install any software or device drivers that are required for the option.

Opening the computer cover

Attention
