one is not available, provide some ESD protection by wearing an antistatic
wrist strap attached to chassis groundany unpainted metal surfaceon
your system when handling parts.
ESD and handling boards: Always handle boards carefully. They can
be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the system, place it on
a grounded surface free of static electricity. Do not slide boards over any
surface.
Cooling and airflow: For proper cooling and airflow, always install the
chassis covers before turning on the system. Operating the system without
the covers in place can damage system parts.
