IP Office IP Phones: Power Supply Options802.3af 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 H323 IP phones supported on IP Office also
support this standard. Note that for phones being used with an add-on unit such as an EU24, EU24BL or BM32, an
individual power supply must be used rather than PoE.
·Exceeding the Class limit of a PoE port or the total Class support of a PoE switch may cause incorrect operation.
4606, 4612, 4624 Gen2
1.Requires the addition of a 1603 PoE Splitter (SAP 700415607).
2.GEN1 versions of these phones cannot use PoE. The GEN of a phone can be determined from the label on
the base of the phone. The label text giving the phone's type, for example 4624D, is followed by two
digits which give its generation (GEN) number, for example 4624D01. GEN1 4612 and 4624 phones can
be Ethernet powered using a 30A Switch Upgrade Base unit.
3.4621SW with a Gigabit Adapter is Class 3.
·Avaya 1152A1 Power Distribution Unit (Mid-Span Power Unit)
This is a 1U high 19-inch rack mountable unit. It is available in models to support 6, 12 or 24 PoE devices
including H323 IP phones. For each device, it provides a RJ45 data in ports and a matching RJ45 data and power
out port. It can support a maximum of 200 Watts or a peak of 16.8 Watts per port.
·Power of Ethernet (POE) Switch
The Avaya P333T-PWR Switch is a Ethernet LAN switch which also provides PoE input for up to 24 devices
including H323 IP phones.
·IP Phone Inline Adaptor
This adaptor allows 4602, 4602SW, 4620, 4621 and 4625 H323 IP phones and 5600 Series equivalents to be
powered from a Cisco Catalyst power blade. Using these adaptors, up to 24 H323 IP phones can be supported on
a single power blade. The phones do not provide the Catalyst switch with information on their power requirements
and future changes to Catalyst switch software may affect operation.
