1. Introduction
“Inline power” is a feature offered on some Ethernet switches. It is a means by which the switch
can supply power to a network device within the same cable that carries the Ethernet signaling.
This simplifies network installation and powering design, removing the need for a separate
power supply for each IP telephone in the network. IEEE 802.3af-2003 defines a standard
protocol to be used by powering and powered devices.
The 3Com SuperStack 3 Switch 4400-PWR is a 24-port (24 10/100Base-TX) Ethernet switch. It
supplies 150 watts of power for PoE applications compatible with the IEEE 802.3af-2003
standard. Avaya 4600 Series IP telephones, Avaya wireless LAN access points, and the 3Com
SuperStack 3 Switch 4400-PWR comply with this standard. These Application Notes show how
Avaya IP telephones and wireless LAN access points can be connected to the 3Com SuperStack
3 Switch 4400-PWR. Web-based configuration that display and control powering status of the
switch ports are also demonstrated.
The Avaya product configurations addressed by these Application Notes are shown in Figure 1.
The following Avaya products are directly connected to the switch:
• 4602 and 4602SW IP Telephones
• 4610SW IP Telephone
• 4620 and 4620SW IP Telephones (including the optional EU24 Button Expansion
Module)
• 4630SW IP Screenphone
• Gen-2 4606, 4612, and 4624 IP Telephones
• Gen-1 4612 and 4624 IP Telephones with 30A Ethernet Switch Base
• AP 3 and AP 5 Access Points
The Gen-1 Avaya 4612 and 4624 IP Telephones require the Avaya 30A Switch Base if power
over Ethernet is required. Figure 2 shows the connections for the 30A switch base. The 4612
and 4624 telephones can be identified as Gen-1 or Gen-2 by inspecting the model number. “1A”
in the model number indicates Gen-1; “2A” 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.
Examples of model numbers are “4612D01A-003” (Gen-1) and 4612D02A-003 (Gen-2).
The powering tests included verification of the following after each product was connected to the
switch:

• Successful boot operation
• For IP telephones, successful registration with an Avaya Media Server/Gateway and
successful completion of calls using the IP telephones (e.g. initiate calls, receive calls,
etc.)
• For wireless LAN access points, successful registration of a wireless laptop and use of
the administration web interface on the access point from the laptop.

3. Configure the 3Com SuperStack 3 Switch 4400-PWR
This section describes the configuration steps to control and monitor inline power status. Either
the command line interface (CLI) or the web-based management interface can be used to
accomplish these tasks. These Application Notes demonstrate the configurations using the webbased interface. By default, the switch tries to obtain an IP address from a DHCP or BOOTP
server on the network. If neither server is found, the switch configures itself with its default IP
address 169.254.100.100. In these Application Notes, there is no DHCP server available in the
configuration.
Steps Description
1.
Access the switch using a web browser
• Configure a laptop or PC with an IP address in the 169.254.100.0/24 subnet. Launch a
web browser and point to http://169.254.100.100.
• Log in using the appropriate credentials as shown in Figure 3.
