1.3 Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It may occur if
electronic printed circuit cards are improperly handled and may cause complete or intermittent failure.
Always follow ESD prevention procedures when removing and replacing modules:
• Ensure that the Tmedia VoIP gateways are grounded.
• Wear an ESD-preventive wrist strap and ensure that it makes good contact with your
skin. Connect the wrist strap clip to an unpainted surface of the Tmedia VoIP Gateway
or the grounded equipment rack in order to channel away all ESD voltage safely to
ground. To guard against ESD damage and shocks, the wrist strap and cord must be
in proper working condition.
• If no wrist strap is available, and you must work with Tmedia VoIP Gateways, ground
yourself by touching a metal part of the chassis.
