R760 resetting / possible thermal issue

[jpcent]

I have two R760 APs powered by Trendnet 10G PoE++ injectors, which provide the correct amount of power.

The access points start at room temperature but gradually heat up and then reboot after about 40–60 minutes of uptime, even with minimal to no network activity. Something is clearly wrong with the devices, and I’m assuming it may be a firmware issue. I’m currently running 118.2.0.0.875, which I was only able to upgrade to using the CLI. After the first reboot, the device continues rebooting every 10–15 minutes. This may be some sort of thermal protection behavior, but I’m not sure.

These APs are not being used for WAN—only for a private network to access audio-visual devices. No other users are on the network besides me.

I am using these as standalone devices. One is set to xxx.xx.x.250 and the other to xxx.xx.x.251. They work properly with except of the reboot cycling.

Please help me resolve this issue.
