1.1.5 Setting PoE Management Mode

S7500 series manage PoE in either auto mode or manual mode. Through the setting of
the management and PoE priority, the switch determines whether to supply power to
newly added PDs when the power supply is almost fully loaded.
auto mode: When the switch is reaching its full load in supplying power, it will first
supply power to the PDs that are connected to the ports with critical priority, and
then supply power to the PDs that are connected to the ports with high priority. For
example, port A is of critical priority. When the switch is reaching its full load and a
new PD is added to port A, the switch will power down the PD connected to a port
with lower priority and turn to supply power to this new PD.
manual mode: When the switch is reaching its full load in supplying power, it will
neither 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 full
load and a new PD is added to port A, the switch will not supply power to this new
PD.
Note:
In auto mode, when the switch is reaching its full load in supplying power, the switch
decides 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.
