Power-On Password
When a Power-On Password is set, you are prompted to type a valid password each time the computer is
turned on. The computer cannot be used until the valid password is typed in.
Administrator Password
Setting an Administrator Password deters unauthorized users from changing configuration settings. If you
are responsible for maintaining the configuration settings of several computers, you might want to set an
Administrator Password.
When an Administrator Password is set, you are prompted to type a valid password each time you try to
access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password
is typed in.
If both the Power-On Password and Administrator Password are set, you can type either password. However,
you must use your Administrator Password to change any configuration settings.
Setting, changing, and deleting a password
To set, change, or delete a password, do the following:
1. Start the Setup Utility program. See “Starting the Setup Utility program” on page 21.
2. From the Setup Utility program main menu, select Security.
3. Depending on the password type, select Set Power-On Password or Set Administrator Password.
4. Follow the instructions on the right side of the screen to set, change, or delete a password.
Note: A password can be any combination of up to 64 alphabetic and numeric characters. For more
information, see “Password considerations” on page 25.
