I was setting up a Dell M100e Chassis network switch. I was going through the network switch configuration wizard and when i reached the end, I realized that I had entered the wrong port value.
I decided I would simply restart. When I did, the wizard I expected did not display properly.
The problem was that there was already a startup-config file so the wizard thought the system was already configured.
Simply delete the startup-config file and execute the reload command. If prompted about the stack, go ahead and reload.
The wizard will begin as normal.
