Tools and Equipment Needed

Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur
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, you must
use the wrist strap and cord properly. 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. It should be between 1 and 10
Caution

power is off.
