Table 3 shows the detected class, maximum allowed power, and measured power by the
Extreme Networks Aspen 8810 Switch for the Avaya IP telephones and Wireless Access Points.
The power was measured when the powered devices were idle.

Table 3 - Class, Power Allocation and Power Measured for Avaya IP Telephone and
Wireless Access Points
The following describes how the Extreme Networks Aspen 8810 interacts with powered
devices.
1. In order for any port to supply inline power, the system, slot and port must be
enabled for power. Auto detection is enabled for all ports by default.
2. The power is reserved for each slot. The reserved power is configurable. The
switch measures the total power consumption of a slot in real time to decide if
there is power available for the next added device. The switch does not reserve
the power for a detected PD.
3. The Extreme Networks Aspen 8810 can detect Avaya PDs with the correct
classifications as shown in Table 3. The switch will deny power to the PDs
exceeding the class limit (Max Allowed Power
in Table 3).
The G48P PoE module on the Aspen supports 48 10/100/1000 ports.
The Aspen supports configuration and control of the power for PoE at the system, slot and port
levels. The Aspen does not allow delivery of more power than is available. The system shares
power among ports on a slot and automatically ensures the slot power budget is not exceeded.
