Safety Precautions
By observing the prescribed safety precautions while working on a system, you
can avoid unnecessary damage to its equipment and disruption of service. The
items on this list should be a regular part of your routine.
!
WARNING:
Failure to comply with these procedures can have catastrophic effects on a
system’s hardware and service. Read the explanations following the list to
ensure a complete understanding of these necessary procedures.
■ While touching any component inside a cabinet, ground yourself using a
wrist strap attached to the cabinet’s frame, and avoid sources of static
electricity.
■ When logging on with Avaya Site Administration (ASA), be aware that
alarm notification is normally disabled. Log off ASA as you leave the
system.
■ Always busy out a server before you power it down.
■ Do not power down either a switch-node or port carrier to replace a board.
■ Handle fiber-optic cables with care. Bending, piercing, or cutting a cable
can sever communications between major subsystems.
■ To disconnect a fiber-optic cable, grasp both the lightwave transceiver and
the cable’s connector.
■ Before powering down a cabinet or carrier containing an EMBEDDED
AUDIX system (TN568), first power down the AUDIX unit to avoid
damaging its software. Instructions for powering down this unit are in
‘‘EMBEDDED AUDIX System’s Power Procedures’’ on page 4-3, on the
circuit pack, and in EMBEDDED AUDIX documentation.
■ When you are finished working on a cabinet, replace and secure every
panel and cover to avoid disseminating electromagnetic interference.
