Reset to Factory Defaults

Occasionally, you may want to factory default/reset a switch. This can be done from the CLI with restore factory-default, but if you've lost the password you'll need to follow this procedure - which should work for any of the Ethernet Switches (450, 460, 470) and the Ethernet Routing Switches 2500 Series, 4500 Series, 5500 (5510, 5520, 5530) Series.

Follow these steps:

  1. Connect to the console port of the switch (9600,8,N,1)
  2. Reboot (power-cycle) the switch.
  3. When the first line of the diagnostics tests is displayed, press CTRL-C. The system then displays a menu.

    Press 'p'  to run POST tests
    Press 'r'  to Receive cascade test packets
    Press 's'  to Send    cascade test packets..
    
  4. Press ' i ' to Initialize config/log flash.

    Erasing     - Done
  5. Press ' a ' to run Agent code. The switch will reboot.
