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 t...
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:
How do I send tech-support files from my Managed Switch to NETGEAR community moderators?
http://kb.netgear.com/app/answers/detail/a_id/31439Could you check the following step by step?
1) remove all of PDs and connect the port from 1/0/1 to 1/0/8 one by one and see if only the port1 doesn't provide the power.
2) If 1/0/1 to 1/0/8 can provide the power if there is only one PD to the switch, move the existing PD to the port 1/0/1, then connect another PD to the 1/0/2, and see if the port 1/0/2 can provide the power.
3) if port 1/0/2 cannot provide the power on step 2, move the PD from 1/0/2 to the port 1/0/5 and see if port 1/0/5 can provide the power.
we saw one issue similar to this before, but please try the step 1 to 3 first, we can see if they are the same issue.
