Classification mode
In this mode each port automatic determines how much power to reserve according to the class the connected PD belongs to,
and reserves the power accordingly. Four different port classes exist and one for 4, 7, 15.4 and 30.8 Watts.
Class Usage Range of maximum power used by the PD Class Dsecription
0 Default 0.44 to 12.95 Watts Classification unimplement
1 Optional 0.44 to 3.84 Watts Very low power
2 Optional 3.84 to 6.49 Watts Low power
3 Optional 6.49 to 12.95 Watts (or to 15.4Watts) Mid power
4 Optional 12.95 to 25.50 Watts (or to 30.8Watts) High power
1. In this mode the Maximum Power fields have no effect.
2. The PoE chip of PD69012 has designed to that Class level 0 will be assigned to 15.4
watts by AF mode and 30.8 watts by AT mode under classification power limit mode. It is
hardware limited.
Allocation mode
In this mode the user allocates the amount of power that each port may reserve. The allocated/reserved power for each
port/PD is specified in the Maximum Power fields. The ports are shut down when total reserved powered exceeds the amount
of power that the power supply can deliver.
In this mode the port power is not turned on if the PD requests more available power.
LLDP mode
In this mode the ports of PoE power is managed and determined by LLDP Media protocol.
