1. Connect the PC and the storage device by using a serial port cable.
2. Note the version of the controllers and select the corresponding troubleshooting method.
3. It is recommended to perform the previous two methods in single controller mode to avoid the improper password synchronization by the authentication module between dual controllers. After the password of one controller is changed, make the system run in the single controller mode. After that, insert the other controller, and the password is automatically synchronized to it. After the dual controllers start up normally, the password is successfully changed.
