CAUTION
Electrostatic Discharge (ESD) can damage equipment and
impair electrical circuitry. It occurs when electronic printed cir-
cuit cards are improperly handled and can result in complete or
intermittent 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.
