Adjunct Power Connection Locations

Return to Task List

Example Adjunct Power Connections shows typical connection locations for adjunct power. Adjunct power for station equipment may be supplied from the equipment room, satellite location, or the work location.

For this figure, the following example is used:

1. If 25 telephones are connected to the system and all 25 telephones need adjunct power, install a bulk power supply in the equipment room.


2. If only ten of the telephones need adjunct power, install a bulk power supply at the satellite location.


3. If only one telephone needs adjunct power, install the individual power supply at the work location.

Powering IP phones

If customers do not want to use local power for their IP phones, they can use either the

• P333T-PWR 24-port Cajun switch that provides power over the Ethernet.


• 1152A1 midspan power unit, which supplies power between the Avaya Media Gateway or Server and IP phones. This power unit also works with the X330 Ethernet expansion module.
