3. IEEE 802.3af PoE implementation on the Avaya PDs and

Extreme Networks PSE

In June 2003, the IEEE approved a standard for Power over Ethernet. The maximum power is

15.4W per PSE port and the maximum power delivered to a powered device, accounting for

cable loss, is 12.95W. Optionally, powered devices may also be classified based on the

maximum power the powered device will draw. Extreme Networks PSEs and Avaya PDs

support this optional classification. The Extreme Networks Summit 300-48 can detect the

Avaya PDs with the correct classification and can be configured to deliver the appropriate

power.

The IEEE 802.3af classifications for the PSE and PD are given in Table 2.

Class PSE Output Max. Power

0 15.4W

1 4.0W

2 7.0W

3 15.4W

4 Treat as Class 0

Table 2 - IEEE 802.3af PSE and PD Power Classifications

Table 3 shows the detected class, power allocated, and measured power by the Extreme

Networks Summit 300-48 Switch for the Avaya IP Telephones and Wireless Access Points. The

power was measured when the powered devices were idle.
