Hello 

i am looking for a device switch or poe adapter for power the zlt x17 and to give internet to omada er7212pc please check picture maybe for better understanding

i already have er7212pc and two wifi accespoint and zlt x17. and wich one first i bought poe injector version TL-POE150S but that one keeps stop working after like between 6 or 12 hours. so i replaced the cables and same issue and i think it needs more power like poe +. And or i think because the injector says power data-out where the zlt x17 is connected then from that to data-in is in connflict. or is it just a switch that works any way in or out.
