If you have assigned a setup password (see "Using the Setup Password" on

password security enabled or to disable password security.
To leave the password security enabled:

prompts you to re-enter your password. You have three attempts to enter the
correct password. After the third unsuccessful attempt, the system displays an
error message that the system has halted and will shut down.
Even after you shut down and restart the system, the error message continues
to be displayed until the correct password is entered.
