Factory Reset
If you forget the root password, it cannot be recovered. You must perform a factory reset to restore it to the default value (the MG90’s serial number).
To perform the factory reset:
Press and hold the Reset button on the MG90’s front panel until all the LEDs turn solid white.
Release the button, and the LEDs remain white while the factory reset is in progress.
When the reset finishes, the MG90 powers off and, if AutoPower is enabled, reboots.
