We will likely have more data on this phenomena later, as we plan to scope out the failed power distribution board under load. It is perhaps notable that we have measured large ripple voltages (up to 0.6v on a WORKING board) on the 5v supply output, and that this is likely a marginal condition for the D-Link, which expects 5v +/- 5%.

Aren't you supposed to power the D-Link AP with the DC-DC converter?
I know you can power the D-Link from that 5V source on the PDB, but you're pushing your luck as you've noticed.
I am absolutely sure this was a requirement last year because we showed up to Palmetto minus that DC-DC converter and electrical tried to get me to overnight it (luckily they found a donor).
