Connect Adjunct Power

Return to Task List

The 400B2 adapter is convenient for connecting local -48 VDC power to a modular plug. See 400B2 Adapter Connecting to a Modular Plug.

Each port network can provide power for up to three attendant consoles. This source of power is preferred for the attendant consoles because it has the same battery backup as the system. See Auxiliary Connector Outputs.


Note: Adjunct power can be provided locally at the telephone or console by either the 1151A1 or 1151A2 power supply. Adjunct power can be provided from the equipment room or equipment closet with the 1145B power unit. Go to Install and Wire Telephone Power Supply for power supply information and installation procedures.
