TSW101 non functional power supply via PoE-Ports

Hi, I need the TSW101 PoE switch for 2 IP cameras. I am using two AXIS IP cameras (P3935-LR M12) and Ethernet cables (M12 to RJ45) from Phoenix Contact (1407502). I connected the cameras to the first and second PoE ports and the router to the “normal” Ethernet port. When I turn on the switch, all the LEDs light up, but only the power LED is lit and the Ethernet port connected to the router shows an active connection. I tested the PoE ports with non-PoE devices and they worked. I used a TP-Link PoE switch (TL-SG1005P) to configure the cameras and everything worked fine. The Ethernet cables I used are coded for PoE alternative A. I read in the wiki knowledge base that the alternatives on the switch were changed in early 2024 to ensure better compatibility with other devices. Could there be an issue with these changes that is causing my problem?
