For example: There are POE PDs connected to the POE Switch and
the total power consumption is 48 watts. The system will reserve 8
watts for a buffer and the POE MAX LED will light up. Once there is
another POE PD inserted, the system will not provide power to the
additional POE PD.
Priority:
This function will help protect the system when the system
power is overloaded. The system will disable the PoE function of
lower priority PoE ports to maintain the power to higher priority PoE
ports.
The total power resource for the system is 56W shared between the 4
POE ports (maximum power for per port is 15.4W). If all POE PDs
power consumption is over 56W, the system will automatically
arrange the priority of these ports. The lower port number will have
the higher priority and the higher port number will have a lower
priority (Highest priority: Port 1 > Port 2 > Port 3 > Port 4).
For example: In this POE Switch, Port 2 is using 15 watts and Port 3,4
is using 15.4 watts, these two ports are using 45.8 watts total. If there
is an additional POE PD inserted to Port 1 with 15.4 watts, the system
power resource is over current and the priority function will activate.
The priority will be applied to the lowest port number to highest port
number, so Port 1,3 will use 15.4 watts, Port 2 will use 15 watts, and
the system will cut off the power to Port 4 due to over current.
