Hi, I am connecting a third party PoE devices, but when I plug PoE into it then its switch port is restarting continuously. Showing error of Imax error detected. How to resolve this critical issue in PoE devices. Thanks & Regards.

Hi, We are using 3850 switch and when I start our PoE device it's restarting continuously in that switch is giving an error of "Imax error" on serial console. Can you please guide us on this issue? Thank you.  

I am getting following message on switch console window:-Mar 31 02:24:21.795: NRGYZ:ENDPOINT:Unable to discover endpoint 10.0.0.4 on GigabitEthernet0/24 due to invalid MAC addressWhat does it mean?
