Currently there is no procedure to recover switch password. If your switch is running 2.0.4-r1 it can be factory reset using the reset button to put the switch back into the pristine condition. Please refer to attached 2.0.4 Release Note for factory reset procedure.
Note: If the switch is running 2.0.1, you need to onboard it with cnMaestro cloud which will automatically upgrade it to 2.0.4, then perform factory reset.
