Password considerations
A password can be any combination of up to 12 alphabetic and numeric characters
(a-z and 0-9). For security reasons, it is recommended to use a strong password
that cannot be easily compromised. To set a strong password, use the following
guidelines:
v Have at least eight characters in length
v Contain at least one alphabetic character and one numeric character
v Setup Utility program and hard disk drive passwords are not case sensitive
v Not be your name or your user name
v Not be a common word or a common name
v Be significantly different from your previous passwords
User Password
When a User Password is set, the computer cannot be used until a valid password
is typed from the keyboard.
Administrator Password
Setting an Administrator Password deters unauthorized users from changing
configuration settings. If you are responsible for maintaining the settings of several
computers, you might want to set an Administrator Password.
After you set an Administrator Password, a password prompt is displayed each
time you try to access the Setup Utility program.
If both the user and administrator passwords are set, you can type either
password. However, to change any configuration settings, you must use your
administrator password.
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 → Set Passwords.
3. Follow the instructions displayed on the right side of the screen to set, change,
or delete the password you want.
Note: A password can be any combination of up to 12 (1 to 12) alphabetic and
numeric characters. For more information, see “Password
considerations.”
