Using the 1152B PDUs
The 1152B PDUs are used to power the 46xx series and 96xx 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 1152B using an in-line adapter.
This adapter provides the resistive signature so that the 1152B allows power to flow to the
telephone. The generation 2 telephones do not need an adapter.
The 1152B PDU has 10/100 Base-T ports, each of which can supply a minimum of 15.4 watts
using the internal power supply and operates on a 100-240 volts AC, 60/50 hertz power source.
The 1152B PDU is 1U high and fits in most standard 19-inch racks. It can also be mounted on a
shelf. Refer to the user’s guide that comes with the unit for complete installation instructions.
Connecting the 1152B PDU cables
All of the ports on the front of the 1152B PDU are configured as data route-through ports for all
data wires (pins 1, 2, 3 and 6).
Use a standard CAT5, CAT6 or CAT6e straight-through Ethernet cable (not supplied), including
all 8 wires (4 pairs) as shown in
Connecting cables to telephones and other end devices on
page 126.
