Overview
Your Dell computer system supports a variety of internal options that expand system capabilities. This
chapter prepares you to install options inside the computer. It describes how to remove and replace the
computer cover and expansion-card cage, as well as rotate the power supply away from the system board. It
also familiarizes you with the internal components you may handle if you install Dell hardware options.
Before You Begin
To make working inside your computer easier, make sure you have adequate lighting and a clean work
space. If you temporarily disconnect cables or remove expansion cards, note the position of the connectors
and slots so that you can reassemble the system correctly.
You will use the information in this section every time you install a hardware option inside your computer.
Read this section carefully, because the information is not repeated in detail elsewhere in this guide.
Safety First — For You and Your Computer
Working inside your computer is safe—if you observe the following precautions.
CAUTION FOR YOUR PERSONAL SAFETY AND PROTECTION OF YOUR EQUIPMENT
Before starting to work on your computer, perform the following steps in the sequence indicated:
1. Touch an unpainted metal surface on the computer chassis, such as the power supply, before touching
anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate
any static electricity that might harm internal components. Also avoid touching components or contacts
on a card and avoid touching pins on a chip.
