Preventing Electrostatic Discharge Damage
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 intermittent
failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that
the router chassis is electrically connected to earth ground. 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.
Caution
between 1 and 10 megohms (Mohm).

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, and missing safety grounds.
If an electrical accident occurs, proceed as follows:
— Use caution; do not become a victim yourself.
— Turn OFF power to the router.
— If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim and then call for help.
— Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
For safety, periodically check the resistance value of the antistatic strap, which should be
