in that case go for it. they probably do have the headers, I believe they all share the same mobo between models (24 port boards and 48 port boards). if the oe board is from a 24 port and you have a 48 port, or vice versa, obviously that won't workI only ask because I already have the power supplies, fans, and Poe board from a dead icx6610. A PoE model is $70 more at the moment. From my memory, they’re .1” headers too, so a cheapish digikey item.
