(3) Relationship between the configuration and the powered port
The following table describes the relationship between the priority setting by the
configuration and the priority of powered port

(4) Stopping PoE power supply
If the total power supply to PDs exceeds 370.0 W, power supply is stopped according to the
priority set to the ports. The Switch stops power supply to PDs with lower priority when the
following condition is met (the resulting value exceeds 370.0 W):
Value for judging the status of power supply (370.0 W) <
Number of class 0 ports × output power (15.4) +
Number of class 1 ports × output power (4.0) +
Number of class 2 ports × output power (7.0) +
Number of class 3 ports × output power (15.4) +
Number of class 4 ports × output power (30.0) +
Total amount of power for the ports for which manual power allocation is set
If the priority of the ports is the same, power supply is stopped from the ports with larger
port numbers. (Priority is given to the ports with smaller port numbers for power supply.)
If the priority setting for powered ports has been set, power supply is stopped from the ports
with lower port priority. (Priority is given to the powered ports for power supply.)
(5) Notifying the warning for power supply
Because the Switch's maximum capacity of power supply is 370.0 W, priority control is
conducted when the total power consumption of all ports exceeds 370.0 W. The threshold
of the trap to issue a power supply warning notification is 340.0 W (about 90 %).
