Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option
or CRU, do not open the static-protective package containing the part until the instructions direct you
to install it.

When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:

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

• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the

edges. Never touch exposed circuitry.

• Prevent others from touching components.

• When you install a static-sensitive option or CRU, 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.

• When possible, remove the static-sensitive part from the static-protective packaging and install the part

without setting it down. When this is not possible, place the static-protective packaging on a smooth,
level surface and place the part on it.

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