Restore Factory Defaults
  
    
      The following two procedures restore the switch to factory defaults and
        reboot the switch. Use the first procedure when you can log in to the switch and issue a CLI
        command and the second when you cannot.
     
    - 
        When you can log in to the switch, use
the following command:
        unconfigure switch
         This command resets most of the
          configuration, with the exception of user-configured user accounts and passwords, the
          date, and the time. On SummitStack, the command also preserves stacking-specific
          parameters so the stack can be formed after reboot. 
- 
        Unset the currently selected configuration image, reset
          all switch parameters, and reboot the switch .
        unconfigure switch
          all 
- 
        If you cannot log in because the switch is in a continuous
booting loop, use the following procedure:
        
          - 
            Reboot the switch while pressing the space bar. This
              puts the switch in Bootstrap mode. 
          
- 
            From the Bootstrap prompt, type
                boot and then press [Enter] and press
              the spacebar. This puts the switch in BootROM mode.
          
- 
            From the BootROM prompt, type config none. 
            The following
              appears: Configuration selected: none 
- 
            From the BootROM prompt, enter
                reboot. The switch reboots and restores the factory
              defaults.
