Make and model of the POE adapter?I have been having a lot of sporadic issues with my Pi shutting down randomly and then corrupting the SD card. I think I isolated it to the POE adapter. My guess is it wasn’t providing adequate power. Just an FYI in case anyone else experiences same issue.
Raspberry Pi model? Any additional Pi hats being powered?
Make and model of the power source? (switch, router, poe injector)
