120 Avaya Application Solutions IP Telephony Deployment Guide
The 1152A1 can be collocated with the data equipment or closer to the endpoints. In all cases,
IEEE 802.3af capable IP devices must connect directly to this PDU. The PDU cannot power any
device if a hub or a switch is between itself and the endpoint because it will not sense the
resistive signature needed to authorize the release of power.
Power modes (Avaya IP Telephones)
The Avaya IP Telephone has four different power modes:
●
Ethernet spare pairs (4/5 and 7/8)
●
Ethernet signaling pairs (1/2 and 3/6)
●
Traditional telephony (7/8)
●
(4630 model only) External transformer with a barrel connector
The 1152A1 power unit powers only through pairs 4/5 (+) and 7/8 (-).
Barrel connector through brick transformer
This brick type transformer provides 5 watts of power to the telephone. The Avaya telephone
treats this brick as the primary power source, and will not accept power from the Ethernet cable
if the barrel is seated into the telephone, with or without the brick attached to AC power.
Ethernet cable through 1152A1 PDU
Adequate power from the 1152A1 is supplied to the generation 2 telephones over the Ethernet
cable. Category 5 or better cable is required for Fast Ethernet to function from the IP Telephone.
Power using adapters
Generation 1 telephones can receive power from the 1152A1 through an in-line adapter. This
adapter provides the resistive signature so that the 1152A1 allows power to flow to the
telephone. The generation-2 telephone does not need an adapter, but it might mistakenly be
used on a generation-2 telephone. Both generation phones work as designed through all tests
performed in Avaya labs.
