Hello,

I have a 10 inch network cabinet with a patch panel where a lan cable from my fritzbox comes in (via keystone module).
From there a cable goes into the PoE switch from Reolink (model RLA-PS1).

At first I thought I could run the CPE210 directly over it, but then I saw that you still have to use the power supply.

Now I come to my problem:
After a factory reset, I reconfigured the CPE210. However, it only worked until I connected it to that Reolink switch. Then the CPE210 reset itself back to factory settings.
I reconfigured the CPE210 again and tested it on another switch and it worked. Then I connected the CPE210 directly to the keystone adapter in the patch panel... worked.

You can also connect non-PoE-capable devices to that PoE switch. For example, I connected my laptop to it and it worked.
 

Is this a known problem? Can the CPE210 not be connected to such a PoE switch, even though the power comes via the adapter?
