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.
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 and other accessories the power requirements are higher. For 9608, 9611, 9621, and 9641 phones, set the phone power switch to H and treat the phone as Class 3.
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.
9608, 9611, 9621 and 9641 Phones
These phones only support a Power over Ethernet (PoE) connector. If not being supplied with a PoE switch, a separate Avaya Global Single Port PoE injector can be used for each phone.
