I mistakenly registered ip 127.0.0.1 in one of the controllers, what should I do?

Question

Computer networks

Good day. There is a controller with a TCP / IP connection, a native program for changing ip to it, connecting to a computer via a switch. Range mesh 192.168.0.X. Foolishly, I decided to check whether the address 127.0.0.1 will be flooded into the controller. Now I'm racking my brains on how to return the controller to the network.

Answer 1

> There is a controller with a TCP / IP connection
Even there is no serial in case of a complete fakap?

Answer 2

Reset to factory settings.
Nothing more can be said without a controller model.
