802.3af Power over Ethernet 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 H.323 IP phones
supported on IP Office also support this standard.
• 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 H.323 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 H.323 IP phones.
• IP Phone Inline Adaptor
This adaptor allows 4602, 4602SW, 4620, 4621 and 4625 H.323 IP phones and 5600 Series
equivalents to be powered from a Cisco Catalyst power blade. Using these adaptors, up to 24
H.323 IP phones can be supported on a single power blade.
Note
• The phones do not provide the Catalyst switch with information on their power
requirements and future changes to Catalyst switch software may affect operation.
*4606, 4612 and 4624 Phones
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.
