If i'm right, the power supply and the PSE part has to be isolated to the rest of the cuircit (NIC etc..). 12V are available, but i need ~48V so i have to design a DCDC boost converter, but i can't ...
Power over Ethernet (PoE) injectors supply or inject direct current (DC) power through network cables to power network devices. They are also called midspans or midspan hubs. PoE injectors enable ...
A PoE injector is also called a "PoE adapter." See PoE. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.
