I followed your commands displayed, (210-24.cfg) (Config)#interface 0/1,(210-24.cfg) (Interface 0/1)#poe,(210-24.cfg) (Interface 0/1)#shutdown , all that last command did was disable the interface 0/1 but poe was still available at the port-
(210-24.cfg) (Interface 0/1)#show port 0/1

I would first run the command "no shutdown " on your interface and then here are your options for PoE on the interface
(210-24.cfg) (Interface 0/1)#poe ?
Press enter to execute the command.

reset Reset PoE port.
