I have read about PoE issue and suggestions on 3750 SW. I do not have option to reboot and it has 15.0 ver. I assume this is the most updated version available by Cisco. I am seeing ports kicking out PoE devices. Any suggestion/recommendations??? I did plug into other available ports but no luck getting device worked. Any feed back related to this topic will help...Thanks!

What is the exact IOS version you are using?
Also, is this an issue with Cisco POE devices connecting to the switch or 3rd party vendors?

Hi Andy,
Please check the available power if you have enough power available and IP PHone is not working, you hit the bug and I would advise you to upgrade to stable release 12.2(55)SE12 or later (58).
