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 procedures requiring ESD protection.
