3.1 Problems on Login Password
3.1.1 Forgot the Login User Password
If you forgot the login user password and cannot login to the system during operation, follow the procedure below.
1. Reporting to the system administrator
First, consult the system administrator. However, if there is no login user eligible for the administrator (e.g., there is
no other login user), perform a default restart and set a password again.
Default restart
Press and hold the reset switch on the system for five or more seconds.
Since security check using a password is not performed, special care must be taken when doing default restart.
The password setting is enabled after starting the system.
2. Changing the password
When a password change is requested, the system administrator must change it and inform all the target login users
of the change (use the password command to change a password, or the clear password command to simply
delete it).

If all the login users with the system administrator privilege forgot the system administrator password and they cannot
enter the system administrator mode, perform the default restart to set up a password again.
Default restart
Press and hold the reset switch on the system for five or more seconds.
Since security check using a password is not performed, special care must be taken when doing default restart. The
password setting is valid after restarting the system.
