Ex1010p - damaged?

ex1010p - strange behavior
This morning I observed a strange thing.
There was a high CPU load on the switch. I did a reboot and strange things started to happen.
First, it showed the POE status correctly on only one port.
So I turned it off for 3 minutes and turned it on again.
Now it lights up the poe diode on all free ports (2 are powered - one is turned off from the poe). In cnmaestro it shows that port DOWN and POE active!

I did a factory reset and it works ?!
A bit abnormal :frowning:

PS
I would like to add that in the moment when all the POE diodes lights, a strange noise of the capacitor was heard from the inside of the device.
After restarting to the factory, the sound stopped.
