Chapter 5. Using the Setup Utility
23
When working with the Setup Utility program menu, you must use the
keyboard. The keys used to perform various tasks are displayed on the
right side of each screen.
Using passwords
By using the Setup Utility program, you can set passwords to prevent
unauthorized persons from gaining access to your computer and data.
See “Starting the Setup Utility program.” The following types of passwords
are available:
• Supervisor Password
• User Password
You do not have to set any passwords to use your computer. However, if
you decide to set any passwords, read the following sections.
Password considerations
A password can be any combination of up to ten characters (a-z and
0-9) and symbols. For security reasons, it is a good idea to use a strong
password that cannot be easily compromised. We suggest the passwords
should adhere to the following rules:
• Must have at least seven characters in length
• Contain at least one alphabetic character, one numeric character.
• Setup Utility program and hard disk drive passwords are not case
sensitive
• Not be your name or your user name
• Not be a common word or a common name
• Be significantly different from your previous password
Supervisor password
When a Supervisor Password is set, it deters unauthorized persons from
changing configuration settings. If you are responsible for maintaining
the settings of several computers, you might want to set a Supervisor
Password.
After you set a Supervisor Password, a password prompt is displayed each
time you try to access the Setup Utility program.
If both the supervisor and user passwords are set, you can type either
password. However, to change any configuration settings, you must use
your supervisor password.
