ESD Precautions
The boards have integrated circuits sensitive to static electricity. To avoid damaging chipsets
from electrostatic discharge, observe the following precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before handling a board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. This will help to discharge any static electricity on a
human body.
When handling boards and components, wear a grounding wrist strap available from
most electronic component stores.
