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.

Never assume that power is disconnected from a circuit. Always check.

If an electrical accident occurs, proceed as follows:

— Use caution, and do not become a victim yourself.

— Turn off power to the system.

— 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
