1.1.2 External PSE2500-A1 Power System

If PSE2500-A1 power system is taken as the external power supply, the power is
distributed as follows:
Input voltage: 100 VAC to 140 VAC
One power supply unit (PSU) of the PSE2500-A1 power system can provide 1250
W of power, and two PSUs can provide up to 2400 W of power.
If the PSUs of PSE2500-A1 power system need to work in redundancy mode,
three PSUs are required and they work together to supply up to 2400 W of power.
Input voltage: 200 VAC to 240 VAC
One PSU of the PSE2500-A1 power system can provide 2500 W of power.
If the PSUs of PSE2500-A1 power system need to work in redundancy mode, two
PSUs are required.

1.1.4 Setting PoE Management Mode

S6500 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 has the priority of critical. When the switch is reaching its full
load and a new PD is now added to port A, the switch will power down the PD
connected to the port with the low 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 take the priority into account 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 now added to port A, the switch just gives a prompt that
a new PD is added and will not supply power to this new PD.
