1.12 Power Supply Options
Each H.323 IP phone requires a power supply. They do not draw power from the phone system. Listed below are the
power supply options that can be used.
Power over Ethernet (PoE) Options
IEEE 802.3af is a standard commonly known as Power over Ethernet (PoE). It allows network devices to receive power
via the network cable using the same wires as the data signals. All the Avaya H.323 IP phones supported on IP Office
also support this standard.
Where a large number of phones is being installed, the use of PoE switches is recommended. For other scenarios,
individual PoE injector devices can be used to add PoE power support to the phone's LAN connection from a non-PoE
switch.

These 1603 and 1603SW phones require a separate PoE Splitter unit in order to use PoE.
·
Exceeding the Class limit of a PoE port or the total Class support of a PoE switch may cause incorrect operation.
·
Note that for phones being used with an add-on button module unit, an individual power supply must be used
rather than connection to a PoE switch.
1600 Series Phones
These phones can use either PoE as above or can be powered from using 1600 Series plug-top power supply units
(PSUs). Different models of PSU exist for the various type of mains power outlets in different countries. The PSU connects
to the phone using a barrel connector under the phone.
4600/5600 Series Spare Wire Power Options
The following power supplies use the normally unused pin 7 & 8 connections in the CAT3 or CAT5 network cable. This is
referred to as "spare wire" or "mid-span" power supply units. They can be used with 4600 Series and 5600 Series IP
phones.
