If the factory default switch is pressed and held for 5 seconds after boot, the switch ports on the
NetVanta 3120 will default to 10.10.10.1 and all access policies will be removed from those interfaces.
If the factory default switch is pressed for 30 seconds, a default configuration will overwrite your
existing configuration and reboot the unit.
