Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when
electronic components are improperly handled and can result in complete or intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components. Ensure that the
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 be used effectively. If no wrist strap is available, ground yourself by touching the metal
part of the chassis.
For safety, periodically check the resistance value of the antistatic strap, which should be between 1

to 10 megohms (Mohm).

General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your
system. Ensure that your site is properly prepared before beginning installation.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
Locate the emergency power off switch for the room in which you are working. Then, if an electrical
accident occurs, you can act quickly to turn OFF the power.
Power OFF the router and unplug the power cord before doing the following:
Installing or removing a chassis
–
Working near power supplies
–
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit. Always check.
Use caution; do not become a victim yourself.
Turn OFF power to the system.
If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and
then call for help.
Determine if the victim needs rescue breathing or external cardiac compressions; then take
appropriate action.
