PoE issues M4300-52G-PoE+
Hi, i have several M4300-52G-PoE+ switches with PoE issues. IP cams and ubiquiti APs lost power from switch and shutdown soon after switch turn on, for example: AP on port 1 goes down cause switch turning off PoE and switch PoE status say "search", there is no errors in log files or status bars, but same model AP on port 2 works perfectly, if i unplug AP from port 1 and plug it to port 2 it start working, but AP from port 2 won't start at port 1. And I have a lot of ports that behave itself in same way. If i reboot switch, port start working but soon issues starts emerging again. Configuration is same for all port. Changing poe or port settings, turning it off or on doesn't change anything.
Do you have any recommendations or solutions?
Here is my switch info and sample configuration for affected port(port 1) and port without issues(port 2)

Welcome to the community!
According to your description, both IP cams and ubiquiti APs can work normal with PoE powered on port2, but cannot work stably on port1, right?
For further analysis, Could you please show detailed PoE info for port1 and port2, just with command as below:
show poe port configuration x/x/x(port1/2 number)
show poe port info x/x/x(port1/2 number)
Hope it helps!

Looks like the configuration is correct.
For further analysis,Could you please provide the tech-support file of the Switch:
