I have a POE camera (DH-SD8A840VI-HNI) and a POE switch (Planet GS-5220-16UP4S2X)
However, the POE camera will not power on when connected to the switch, even when this camera is the only device connected. I have to set "force power = true" to the port that the camera is connected to for it to work.
I tried the following:
DH-SD8A840VI-HNI + Planet POE-171A-BT POE injector - OK
DH-SD8A840VI-HNI + Planet GS-5220-16UP4S2X (force power) - OK
Planet GS-5220-16UP4S2X + other brand 802.3bt camera - OK
Planet GS-5220-16UP4S2X + other brand 802.3af camera - OK
What is the best way to troubleshoot this?
