[FGSW-2620PVM] Why FGSW-2620PVM could not provides power for 16 class ID#3 devices over Ethernet when I set Power Limitation mode to Priority mode?


1. According to IEEE 802.3af standard, the Class ID level 3 power usage maximum is 12.94 Watts, so FGSW-2620PVM is going to reserve12.94 Watts for every single device even they are not using full power. However, 16 class ID level 3 devices will need 207.04 Watts totally and it was over FGSW-2620PVM PoE power supply budget (190 Watts).
2. If you want to force power on the PDs (Powered Device), please set the power limit mode to “No Limit” and then the system will ignore the PoE power reserved request by classification. But please be noticed that the No Limit mode may cause PoE power supply damage because system will keeps feeding power for each port till the PoE power supply damaged.
