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) in a Switch that supports IEEE 802.3af
only. Optional, 12.95 to 25.50 in a Switch that supports IEEE 802.3at.
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.
