A total of 57 watts is available for the four powered ports 4x PoE. E.g. port 1/ 17 watts, port 2/ 15 watts, port 3/ 12 watts and port 4/ 13 watts.
This is what it says here at Galaxus. - Intelligent Power Management As soon as the total power consumption of the PoE-powered devices is greater than or equal to 57W, the PoE ports are prioritised. To protect the system in the event of overload, a decision is then made to distribute the power or switch off the power supply at the port with the lowest priority.
