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%.

Yep, one and only one PD. However, ripple is not normal and the five volt output is to be used for the camera only. The correct wiring is to connect the five volt convertor to the +12 volt 'radio' output on the PD. The output of the convertor then feeds the radio.
Any idea what frequency the ripple was?
