Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and
other components. Always observe the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are ready to install it.
- Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit throughout any
procedure requiring ESD protection.
