Password considerations

A password can be any combination of up to 16 (1 to 16) 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. A strong password should adhere to
the following rules:
v Have at least eight characters in length and contain at least one alphabetic
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 password

Power-On Password

When a Power-On Password is set, the user is prompted to type a valid password
each time the computer is turned on. The computer cannot be used until a valid
password is typed in.

Privileged Access Password

Setting a Privileged Access Password deters unauthorized people from changing
configuration settings. If you are responsible for maintaining the settings of several
computers, you might want to set a Privileged Access Password.
After you set a Privileged Access Password, a password prompt is displayed each
time you try to access the Setup Utility program.
If both the Power-On Password and Privileged Access Password are set, you can
type either password. However, to change any configuration settings, you must use
your Privileged Access Password.
