Squama Ethernet with POE

I just received my Squama Ethernet module, with POE.
I can download a sketch on it, run the webserver example, … but once I disconnect the USB, I have now power.

I tried with POE active, passive, … nothing work, I found it use a TPS2376 from texas, who is Class 3 PoE, so it should work with active POE.

Any advice ?
