There is - here are the counters: https://imgur.com/a/FdVP9IF Note that bb5/6/7 have been losing power frequently too.
If the voltage is too low, why would they randomly reboot maybe once or twice a week and then be fine for months at a time? The runs are well under 100m. 24vdc feeds the NEMA enclosure, then we have maybe 25 feet of cat5 to APs. I would think it's no more than 1 volt loss from my 24v source to the AP, but I have not verified this. I know it's 24v at the green terminal block to the POE injector/Gigabit Sync injector.
