How to reboot your PoE device

Alot of businesses have Power over Ethernet VoIP phones plugged in and sometimes it would come in handy to reboot those phones remotely. Here is an idea on how.. shut off the power to them and then turn it back on.

Shut off PoE on a switch port / interface (you could use the interface range command to shutoff multiple interfaces instead of just one)

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface fastethernet 5/2

Switch(config-if)# power inline never

Switch(config-if)# end

Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface fastethernet 4/1

Switch(config-if)# power inline auto

Switch(config-if)# end

Switch# show power inline fastethernet 4/1
