I’m thinking of experimenting with clustering RPis, but the thought of that mess of equipment (switch + multi-port USB charger) and cables is a bit of a turn-off.

Does anyone know if there are any limitations to running a cluster of Pis with power-over-ethernet? I’ve googled around but haven’t found any reference to anyone doing this before.

(I know you need the HAT to get PoE support, just wondering if there are any reasons it wouldn’t be viable.)

    Note, not all ports on all PoE switches will actually support PoE, and there may be a total current draw that limits the number of Pis you can connect as a Pi can draw > 500 mA easily. – Fred Sep 20 '19 at 8:47
