Allows user to select 802.3at or 802.3af compatibility mode. The default value is
802.3at mode.
This function will affect PoE power reservation under the power limit classification
only. As in 802.3af mode, the system will reserve a maximum of 15.4W for PD
that supports Class3 level. As in IEEE 802.3at mode, the system will reserve
30.8W for PD that supports Class4 level.
From class1 to class3 level in the 802.3at mode, the PoE power will be reserved
the same as that in 802.3af mode.
The Priority represents PoE ports priority. There are three levels of power priority
named Low, High and Critical.
The priority is used in case the total power consumption is over the total power
budget. In this case, the port with the lowest priority will be turned off, and power
for the port of higher priority will be offered.
It can limit the port PoE supply wattage. Per port maximum value must be less
than 30.8W watts; total ports values must be less than the Power Reservation
value. Once power overload is detected, the port will automatically shut down
and continue to be in detection mode until Pad's power consumption is lower
than the power limit value.
