today i was looking at a 3750 switch and i found that support power inline command, but when i tried to apply this command in a n interface im taking a message that the specific interface (Gi 1/0/xx) does not support power inline...
Do i need any special module or i miss anything ?
Do "show ver". if you switch model has -PS- it supports poE, else it does not and cannot be upgraded to.
Hope this helps, please rate post if it does!
