Depending on which type of cabinet you are powering down, do one of the following:
ADDITIONAL INFORMATION:
In an AC-powered multicarrier cabinet, set the circuit breaker to OFF at the power-distribution unit.
In a DC-powered multicarrier cabinet, turn off the DC power supply.
In an AC- or DC-powered single-carrier cabinet stack, turn off the power for each affected carrier individually. The ON/OFF switch is located behind the:
AC carrier’s WP-91153 power unit
DC carrier’s 676B power unit
Power is restored by reversing the action taken above.
ADDITIONAL INFORMATION:
Restoring power will cause a restart. This process is described under EXP-PN in ABRI-POR (ASAI ISDN-BRI Port) in Avaya Aura® Communication Manager Alarms, Events, and Logs Reference.
If a powered-down carrier contains a 676B power unit, the 676B must have been powered down for at least 10 seconds for the unit to restart.
