I have a Ruckus ICX 7450-48P that is having issues with a few new wireless access points. Under inline power I am getting a fault error "illegal class reported by PD" for 4 of these ports with these access points. There are 2 other of these same exact APs plugged into 2 different ports that work fine. I've doubled checked the config on these ports and compared it to the working ports. Everything appears identical. I'm not sure what is causing this issue.
It's hard to say without being able to see any output. I would recommend opening a support case and gathering a 'show tech' and the data I requested above. That should be a good start in order for one of our engineers to take a look.
