When the majority (or near majority) of ports are supplying 48V passive PoE to UBNT Wave APs, the switch will enter a soft boot loop.
Behavior:
Switch repeatedly reboots / never fully stabilizes
Appears to be a soft loop (not a hard brick)
Occurs after enabling ports all at once or after reboot under load
Does not occur if you slowly power up ports one at a time but will act up again if switch ever reboots
Workaround:
Downgrading to 1.5.14 immediately resolves the issue
System becomes stable again under the same load conditions
Wouldn't using the "Boot Start Delay" on the Power tab be a better workaround than downgrading the firmware?
I don't want to have to setup boot start delays on 2500 switches. This is a firmware issue since downgrading to 1.5.14 resolves the issue. I would be happy to work with netonix to help replicate this issue so this can get resolved in a future firmware.
You have 2500 switches all loaded the same way or is it only some of them? Not telling you how to run your business but boot delay is there for a reason. Have you tried it on your worst offender (or most critical) sites? I'm curious if it is even a possible solution (albeit with significant pain to implement on many sites).
Certainly it would help if there was a way to script mass changes (as I think a number of us have done keyboard mashing sessions on many many devices and it sucks).
Honestly, the differences between the old firmware and new firmware are significant. Maybe the old firmware started PoE up in banks - who knows? The new version is better with less vulnerabilities and I doubt Netonix will have the time and resources to try to roll back in whatever the difference is (it has been very quiet here lately TBH).
