PoE Enable: Select to enable or disable the PoE function.
Power Limit: This function allows you to manually set the port power current limitation to be given to the PD. To protect the DES- 1228P and the connected devices, the power limit function will disable the PoE function of the port when the power is overloaded. Select from "Class 1 (4W)", "Class 2 (7W)", "Class 3 (15.4W)" and "Auto" for the power limit. "Auto" will negotiate and follow the classification from the PD power current based on the 802.3af standard.
