Before you install any computer component, we recommend that you 
read the following sections.  These sections contain important ESD 
precautions along with preinstallation and post-installation 
instructions.

ESD precautions

Electrostatic discharge (ESD) can damage your processor, disk drives, 
expansion boards, and other components.  Always observe the 
following precautions before you install a computer component:

1

Do not remove a component from its protective packaging until 
you are ready to install it.

2

Wear a wrist grounding strap and attach it to a metal part of the 
computer before handling components.  If a wrist strap is not 
available, maintain contact with the computer throughout any 
procedure requiring ESD protection.

Preinstallation instructions

Always observe the following before you install any component:

1

Turn off your computer and all the peripherals connected to it 
before opening it.  Then unplug all cables from the power outlets.

2

Open your computer according to the instructions on page 49.

3

Follow the ESD precautions described above when handling a 
computer component.

Remove any expansion board(s) or peripheral(s) that block access 
to the DIMM sockets or other component connector.
