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 internal power
supply and operates on a 100-240 VAC, 60/50 hertz power source.
The 1152A1 PDU is 1U high and fits in most standard 19-inch (48-centimeter) racks. It also can be
mounted on a shelf. See the user's guide that comes with the unit for complete installation instructions.
