POW-SUP Alarm

[coolwhisper]

I received a minor POW-SUP alarm with error type 2305 on one of the power supplies in a G650. The error count was 3. The alarm self cleared within a minute. A check of the Maintenance Alarm manual gives the description "aux sig lead failure" but there is no further information. An online search did not produce any results. I checked status environment and the voltage is within tolerance. The board passes when I run test board css long. I didn't run the Power Supply Recycle Test since it is destructive. Can anybody shed some light on this? I don't like mysteries.
