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. The IEEE 802.3af standard defines the mechanisms for Power Sourcing

Equipment (PSE), such as PoE-enabled Ethernet switches, to detect, classify, and supply power

to Powered Devices (PDs), such as PoE-enabled IP telephones. The Cisco 2811 Integrated

Service Router, when installed with the EtherSwitch Service Modules with IEEE 802.3af

Support, provides 16 ports with PoE.

The Avaya product configurations addressed by these Application Notes are shown in Figure 1.

The following Avaya powered devices were covered:

• Avaya one-X DeskPhone Edition IP Telephones : 9610, 9620, 9630, 9630G, 9640 (with

SBM24), 9650

• Avaya 46xx Series IP Telephones: 4601, 4602, 4610, 4621, 4622, 4625

• Avaya one-X Deskphone Value Edition IP Telephones: 1603 with PoE Splitter, 1608,

1616 (with and without BM32 Button Module)

• Avaya Quick Edition: 4610, 4621, and G10 PSTN Gateway

3. Configuration of the Avaya endpoints

There is no configuration requirement on the Avaya endpoints to use PoE. For details on

configuring Avaya Servers, Gateways, or Endpoints, consult the Administrator’s guide [1].

4. IEEE 802.3af PoE Implementation on the Avaya PDs and

Cisco 2811 Integrated Services Router

In June 2003, the IEEE approved a standard for Power over Ethernet that allows a maximum of

15.4 W per PSE port. The maximum power delivered to the device, after cable loss, can be no

more than 12.95W. Optionally, the powered devices can be classified according to the maximum

power the device uses. This optional classification is supported on the Cisco 2811 Integrated

Services Router and Avaya PDs and the appropriate power is allocated to the PD.

The IEEE 802.3af classifications for the PDs are given in Table 1. Note that Class 0 and Class 3

are identical. The reason for this is that Class 0 covers the case where a powered device is

detected but the PSE cannot assign the powered device to Classes 1, 2, or 3.

Class PSE Output Max. Power

0 15.4 W

1 4.0 W

2 7.0 W

3 15.4 W

4 Treat as Class 0

Router to the Avaya IP Telephones.

5. Configuring Inline Power on the Cisco 2811 Integrated

Services Router

The Cisco 2811 Integrated Services Router installed with a NME-16ES-1G-P EtherSwitch

Service Module and Cisco 2811 AC inline power supply (PWR-2811-AC-IP) supports 160 Watts

of inline power, which is enough to support Class 2 and some Class 3 PDs on all 16 ports. The

testing associated with these Application Notes did not cover loading of all ports on the PSE.

The ports connecting to the Avaya IP Telephones must be set to the default auto mode in order

to receive power from the router.

To access the router, connect the console cable to the PC’s serial port with the other end

connected to the router’s console port located at the front of the router. Use HyperTerminal to

access the console.

Assign an IP address to the interface associated with the EtherSwitch Service Module and then

open a session to it.

routername#config t

routername#interface gigabitEthernet 1/0

routername#ip address 10.1.20.15 255.255.255.0

routername#no shut

The power inline of each port is set to auto by default. The command show power inline will

display the inline power configuration and status.

To change the power mode, access the port interface and then use the command power inline

<auto|never|static>. The mode should be set to auto for Avaya IP Telephones to work.
