Electronics friends: I have a PoE hat for the Raspberry Pi that died in my cluster.
When connected to the switch, what I believe is the inductor (big package 330 on it) gets searingly hot.
I believe the inductor(?) burned out, but I am interested in why it could have failed.
@Rika Hmm, I'd expect the FETs to get hot if they failed... A schematic would be useful...
Can you measure the resistance across the inductor?
And do you know whether the PoE supply is isolated from ground? This PoE converter only has an inductor instead of a transformer, I think it assumes that the supply is isolated for that to work...
