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 system 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
system unit before handling components. If a wrist strap is not
available, maintain contact with the system unit throughout any
procedure requiring ESD protection.
Preinstallation instructions

your computer” on page 41.
