WS-12-250 on 1.5.0 Board Rev F
Port 4 is supplying 48v power even though the interface says it is off. We can plug in a polycom phone/wifi ap and it will be powered even though the port poe is off. The PoE light on the port is not lit. If we select 24v, it does change the output to 24v, but when Off or 48v is selected it outputs 48v. We used an ethernet PoE tester to double check. Not sure what triggered it, a ruckus r510 was powered on the port for a few weeks before we noticed, but it could have been a problem before that. Also even though the device is getting powered, it shows as 0 watts in the UI.
Tried soft reboot and unplug/replug power from the ups.
Port always powered no matter what UI says

You have a failed or damaged MOSFET, you need to RMA it to get fixed
