1. Introduction
Power over Ethernet (PoE) allows both power and data to be simultaneously carried over
standard Ethernet cables. PoE-enabled Ethernet switches can supply power directly to Ethernet
devices, thereby simplifying installation and removing the need for separate power supplies for
those devices. In the configuration described in these Application Notes, a Dell PowerConnect™
3448P switch is configured to supply inline PoE to Avaya Powered Devices (PDs), specifically
Avaya IP Telephones and Avaya Wireless Access Points.
The Dell PowerConnect™ 3448P allows the prioritization of power to ports. There are three
levels of priority that can be assigned. The default priority is labeled “Low”. The highest
priority is labeled “Critical” and the middle priority is labeled “High”.
As illustrated in Figure 1, the Avaya IP endpoints covered in these Application Notes include
the following:
• 4601 IP Telephone
• 4602 IP Telephone
• 4602SW IP Telephones
• 4610SW IP Telephone
• 4620 IP Telephone
• 4620SW IP Telephone
• 4621SW IP Telephone
• 4622SW IP Telephone
• 4625SW IP Telephone
• 4630SW IP Telephone
• 5601 IP Telephone
• 5602SW IP Telephone
• 5610SW IP Telephone
• 5620SW IP Telephone
• Avaya Gen-2 4606, 4612, and 4624 IP Telephones
• Avaya AP-8 Wireless Access Point
The Avaya 4612 and 4624 IP Telephones can be identified as Gen-2 by inspecting the model
number. “2A” in the model number indicates Gen-2. The model number can be found by:
• Inspecting the label attached to the bottom of the Telephone.
OR
• Pressing Mute, V, I, E, W, # on the keypad and then pressing
* until the model number
appears. Press # to exit.
An example of a model number is 4606D02A-003 (Gen-2).
