[AFMUG] PMP450 5ghz AP possible case water intrusion

[Colin Stanners]

I'm investigating a PMP450 5ghz AP (old unit - the original ones that came
with the FSK port) that failed on the tower.  RJ45 and especially RJ12
ports have white dots on the pins.  Looking in the case, there seems to be
evidence of water intrusion coming from the little temperature/humidity
control membrane-covered hole in back. But a quick test of dripping water
on the case does not cause water intrusion in that hole.  Has anyone else
seen such issues with older PMP450 APs?
