It's the stock power supply, it's not a good one and is failure prone with the thermal design of the thing. the SL model I suggested on reddit (and was posted in this thread) is a completely different model that I've had no issues with. No idea what you're talking about with firmware corruption or PoE reputation, out of nearly 200 pages now of nothing but ancient used switches in the networking section, I think we've had maybe 3 or 4 failed PoE boards total and if I remember right they were all from outdoor PoE devices without surge protection. Aside from the g-electronic fiasco of course, who was knowingly selling broken switchesThe thing is, if you really think about it - it's either prone to eating power supplies, unless there's something significantly different with this PSU (upgraded capacity, different revision), the same issue might just happen again.
A) The original PSU was a dud and had a batch/widespread manufacturing issue
B) The board was drawing too much current or spiking because of POE (again, just a theory, but given how shitty Brocade's reputation is with the POE switches, though more about firmware corruption...), it might just break the PSU eventually too.
I hope the seller doesn't accept my BO. I've changed my mind
Edit: Retracted offer.
