Using the 1152A1 Power Distribution Unit
The 1152A1 PDU is used to power the 46xx series of IP telephones in addition to providing 10/
100 megabits per second Ethernet connection.
Generation 1 Avaya IP telephones can receive power from the 1152A1 via an in-line adapter.
This adapter provides the resistive signature so that the 1152A1 allows power to flow to the
telephone. The generation 2 telephones do not need an adapter.
The 1152A1 PDU has 24, 10/100 Base-T ports, each can supply up to 16.8 watts using the
