8.8.1 PoE Setup
Use this screen to set the priority levels for the Switch in distributing power to
PDs.
Class This shows the IEEE 802.3af power classification of the PD.
This is a number from 0 to 4, where each value represents a range of
power (W) and power current (mA) that the PD requires to function. The
ranges are as follows.
• Class 0 - Default, 0.44 to 12.94
• Class 1 - Optional, 0.44 to 3.84
• Class 2 - Optional , 3.84 to 6.49
• Class 3 - Optional, 6.49 to 12.95
• Class 4 - Reserved (PSEs classify as Class 0)
PD Priority When the total power requested by the PDs exceeds the total PoE power
budget on the Switch, you can set the PD priority to allow the Switch to
provide power to ports with higher priority first.
• Critical has the highest priority.
• High has the Switch assign power to the port after all critical priority
ports are served.
• Low has the Switch assign power to the port after all critical and high
priority ports are served.
Consuming
Power (mW)
This field displays the current amount of power consumed by the PD from
the Switch on this port.
Max Power
(mW)
This field displays the maximum amount of power the PD could use from
the Switch on this port.
Max Current
(mA)
This field displays the maximum amount of current drawn by the PD from
the Switch on this port.
