Does anyone know what this means?

Here's the complete log (the err-disable and then re-enabling of the port):

I have this problem too.

Which platform is it and software version ? And what type of POE devices are in use. We have seen this issue in the past because of ESD ( Electro Static Discharge ) specially seen in the IP phones when they are used with the headsets. One thing you can try is to remove the headset ( if one is being used ) and see if the phone powers up. The message itself is complaining about the fact that more power is being drawn then the port can allow.

Thanks for your help. Not sure if a headset is attached, but I'll check. As for the other questions, here you go:
