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 web-
based 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.

Configure switch port inline power
1. Click Device View on the Toolbar.
2. Select Physical Interface -> Power -> Configure in the navigation panel;
3. The following window displays the switch default power configuration.
Figure 5: Port Inline Power Configuration
Note that for all ports, Power State is Inactive and Profile is set to Not Guaranteed, as there
are no Powered Devices (PDs) connected to the switch.
The screen lists the following information for all the switch ports:
Power State
The Power over Ethernet status for that port. This can take one of the following values:
• Active — The port is currently delivering power.
• Inactive — No device is currently requesting power from the port.

• Disabled — The port has been configured not to supply power.
• FAULT — The port is in error.
Profile
The Profile that has been selected for a port. This can take one of the following values:
• Guaranteed — The device on the port has power reserved for it, as listed in the Limited
To column.
• Not Guaranteed — The device on the port has no power reserved for it. It will receive
power if the switch is below its maximum power budget, and all ports with higher
priorities are receiving power.
Limited To
The power that has been guaranteed to a device. If no power has been guaranteed, a hyphen
('-') is displayed and the port is limited to 15.4 watts as defined in the Power over Ethernet
specification (IEEE 802.3af-2003).
Current
The power that is currently supplied to a port. If no power is currently supplied, a hyphen ('-')
is displayed.
Peak
The maximum power that has been supplied by a port since the counter was last reset.
The following example can be used to verify that the switch can auto-detect the PDs and
supply power to them.
• Plug the Avaya 4620, 4612 and 4602SW IP phones into ports 1-3.
• Click Refresh as shown in Figure 5. Figure 6 shows that all three IP telephones are
automatically powered up, and the power status is changed to Active. Note that the
Current and Peak power for all three IP telephones are displayed also.

Configure port power profile.
By default, the maximum power for all ports is not guaranteed. To guarantee that PDs get their
specified maximum power, their profile can be configured using the Guaranteed profile.
Guaranteeing Power on a Port
To guarantee power to a port:
In the Port column, select the port or ports that are guaranteed for power.
In the drop-down box:
• Select the profile that corresponds to the switch ports connecting to that device type.
Or
• Select Guaranteed and enter the maximum power required by the device type in the
text box that appears below.
• Click Apply.
Repeat for each type of device that needs guaranteed power.

For example, follow the steps above to change ports 1-3 to use the guaranteed profile.
Figure 7 shows all three ports are configured to use the Guaranteed profile. Note the power
limit is set to 15.4 watts for ports 1 and 2, and 7 watts for port 3, since both the 4620 and 4612
IP telephones are class 3 devices and the 4602SW IP phone is a class 1 device.
Table 2 shows the required power allocations defined by IEEE 802.3af-2003, based on the
class.
