My MX65 is not powering anything via the PoE ports.
I've poked around and the MX does not display its switch ports like the Meraki switches do. I even used our Netscout to see if the PoE was working and it alwys came back as no PoE.
I cannot find anywhere to see if the PoE is on or what the power budget is.
Check the configuration, I know on the switches I can enable/disable manually the PoE, its possible that might be the issue. Also assuming your testing this on ports 11/12
