1. Introduction
Power over Ethernet (PoE) telephones are supplied power over the CAT-5 cable that
connects them to the Layer 2 switch. This eliminates the need for a separate power supply
to power the telephone. For it to work, the port the telephone is connected to must
support Power over Ethernet or have a power adapter placed in series between the switch
port and the telephone. The Layer 2 switches are power sourcing equipment (PSE) and
comply with the IEEE 802.3af standard protocol. The telephones are powered devices
(PD) that also comply with the IEEE 802.3af standard protocol.
All of the ports on the Cisco 2811 Integrated Service Router were capable of providing
Power over Ethernet.
The Avaya product configurations addressed by these Application Notes are shown in
Figure 1. The following Avaya Powered Devices are directly connected to the router:
• Avaya 4601 IP Telephone
• Avaya 4602 IP Telephone
• Avaya 4610 IP Telephone
• Avaya 4620 IP Telephone

• Avaya 4622 IP Telephone
• Avaya 4625 IP Telephone
• Avaya 5601 IP Telephone
• Avaya 5602 IP Telephone

The Avaya 4606, 4612, and 4624 are identified as Gen-2 by the 2A in their model
number. The model number can be found by:
• Inspecting the label attached to the bottom of the telephone.
Or
• Pressing the Hold or Mute, V, I, E, W, # on the keypad and then pressing the *
button to cycle through everything, and then the # button to exit and resume
