Installing options

This chapter provides instructions for installing or replacing options in your

computer. For a list of supported options for your computer, go to

http://www.ibm.com/pc/; then, select your country and navigate to the list of options

for your computer.

Installation guidelines

Before you begin installing options in your computer, read the following information:

v Review the safety information beginning on page 129 and “Handling

static-sensitive devices.” This information will help keep you safe while working

with your computer and options.

v Ensure that you have an adequate number of properly grounded electrical outlets

for your computer, monitor, and other devices that you will connect to the

computer.

v Back up all important data before you make changes to disk drives.

v Have a small flat-blade screwdriver available.

v The blue color on components and labels identifies touch points, where you can

grip a component, move a latch, and so on.

System reliability considerations

To help ensure proper system cooling and system reliability, ensure that:

v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed.

v There is adequate space around the computer to allow the computer cooling

system to work properly. Leave approximately 50 mm (2 in.) of open space

around the front and rear of the computer. Do not place objects in front of the

fans. For proper cooling and airflow, replace the computer cover before turning

on the computer. Operating the computer for extended periods of time (over 30

minutes) with the computer cover removed might damage computer components.

v You have followed the cabling instructions that come with optional adapters.

v You have replaced a failed fan as soon as possible.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your computer. To

avoid damage, keep static-sensitive devices in their static-protective packages until

you are ready to install them.

To reduce the possibility of damage from electrostatic discharge, observe the

following precautions:

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

you.

v Handle the device carefully, holding it by its edges or its frame.

v Do not touch solder joints, pins, or exposed circuitry.

v Do not leave the device where others can handle and damage it.

v While the device is still in its static-protective package, touch it to an unpainted

metal part of the computer for at least 2 seconds. This drains static electricity

from the package and from your body.
