@Adam when I have seen this happen - I believe the MX65 gets into some kind of funny hardware state. When it gets into this state it affects both PoE ports.

I have seen it happen to maybe 5 different MX65's now. I would call this kind of failure rate low, but its enough that when someone describes the same problem to me again I go "that one again".
