Unable to Connect to B57-4

Model: B57-4-Color

OS: Ubuntu 20.04
Switch: TL-SG1005P
POE++ Injector: TPE-119GI
NxView: 4.1.1003

Hi,
I am not able to connect/discover a B57-4 from NxView after running the network configuration wizard.
I tried connecting its 5m GigE cable through a POE++ injector connected to an un-managed switch (that happens to be POE+). The green light at the back the camera starts red and turns green after a few seconds. But the link LED on the corresponding port of the switch does not turn on (link is not up). I get the same result if I connect the camera to the switch directly (POE+).

The link LED on the switch port of my laptop blinks after the wizard has configured the adapter. The firewall is off.

I am able to connect my own laptop through the injector (link LED on). I am also able to route traffic through the switch between my laptop and other devices.
I get the same result with a Windows machine.
Below are the specs of of my system and screenshots of NxView.
Thank you for your help,
Charles

Hi @cerignac

the LED behavior you describe (red, then green) looks like the camera is booting up normally, so the link should also come up a few seconds after the LED has turned green. There is certainly something wrong with the Ethernet connection in this case. Somehow the PoE++ supply works, as the LED turns green, but it cannot establish an Ethernet connection.

Do you have another M12/RJ45 cable to rule out any issue with that? I guess you used another RJ45/RJ45 cable when connecting your laptop to the injector, right? Do you happen to have a DC supply at hand, to see if this makes a difference?

best regards, Rainer
