ESD Precautions
To avoid damaging electronic equipment from electrostatic discharge (ESD),
always observe the following precautions before installing any system
component:
1. Do not remove a board from its packaging until you are ready to install it.
Integrated circuits (ICs) on expansion boards are highly sensitive to static
electricity.
2. Wear a wrist grounding strap before handling electronic components.
Wrist grounding straps are available at most electronic component stores.
