Through the setting ofthe management and PoE priority, the switch determines whether to supply power tonewly added PDs when the power supply is almost fully loaded.z auto mode: When the switch is reaching its full load in supplying power, it will firstsupply power to the PDs that are connected to the ports with critical priority, andthen supply power to the PDs that are connected to the ports with high priority. Forexample, port A is of critical priority. When the switch is reaching its full load and anew PD is added to port A, the switch will power down the PD connected to a portwith lower priority and turn to supply power to this new PD.z manual mode: When the switch is reaching its full load in supplying power, it willneither consider the priority nor make change to its original power supply state.For example, port A has the priority critical. When the switch is reaching its fullload and a new PD is added to port A, the switch will not supply power to this newPD.Note:In auto mode, when the switch is reaching its full load in supplying power, the switchdecides whether to supply power to remote PDs on a port based on the port priority.Note that the switch can only compare the priority of ports on the same board.1.2 PoE Configuration1.2.1 PoE Configuration Task ListComplete the following tasks to configure PoE:Task RemarksConfiguring the PoE Feature of a Switch RequiredConfiguring the PoE Feature of a PoE-enabled Board Required
