Task 3: Review Safety Considerations
!
WARNING:
Electronic equipment can be damaged by electrostatic discharge. Do not
touch any electronic component unless you are properly grounded.
!
DANGER:
Do not touch the switch backplane while installing the DEFINITY AUDIX
system. The backplane contains dangerous voltages and current.
To prevent damage to the equipment and yourself, adhere to the following:
■ Make sure you are familiar with the procedures necessary to prevent
electrostatic damage to the equipment.
■ Properly ground a wrist strap.
■ Place the grounded wrist strap on your bare wrist. (The wrist strap must
contact your bare skin directly—do
not wear it over your clothes.)
■ Do not remove the DEFINITY AUDIX System assembly from the
polyethylene bag until:
— Your wrist strap is on your wrist and properly grounded
— You have made room in the switch carrier and you are ready to
insert the DEFINITY AUDIX System assembly in the carrier.
■ If you need to work on the DEFINITY AUDIX System assembly — that is,
disassemble it — place the assembly on a grounded antistatic work mat.
