Preventing electrostatic discharge damage
When starting to install interface cards place the interface card on its shielded plastic bag if you lay it on your bench.
General observations
•
Clean the case with a soft slightly moist anti-static cloth
•
Place the unit on a flat surface and ensure free air circulation
•
Avoid exposing the unit to direct sunlight and other heat sources
•
Protect the unit from moisture, vapors, and aggressive liquids
Electrostatic Discharge (ESD) can damage equipment and impair
electrical circuitry. It occurs when electronic printed circuit cards
are improperly handled and can result in complete or intermit-
tent failures. Do the following to prevent ESD:
•
Always follow ESD prevention procedures when removing
and replacing cards.
•
Wear an ESD-preventive wrist strap, ensuring that it makes
good skin contact. Connect the clip to an unpainted surface
of the chassis frame to safely channel unwanted ESD voltages
to ground.
•
To properly guard against ESD damage and shocks, the wrist
strap and cord must operate effectively. If no wrist strap is
available, ground yourself by touching the metal part of the
chassis.
