Insufficient Power for POE/UPOE device. Replace with compatible FEP and Power-Cycle the Switch

Any Idea what causes this ? Is this a hardware problem or what exactly ?

I can confirm that i had the same error message after i installed a fresh IOS on a 3650. 
I tied a new PSU in the switch throwing the error and it worked fine.
