Password considerations
A password can be any combination of up to 64 alphabetic and numeric characters.
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 password
Power-On Password
When a Power-On 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 Power-On and Administrator passwords are set, you can type either
password. However, you must use your Administrator Password to change any
configuration settings.
Hard Disk User Password
When a Hard Disk User Password is set, it prevents unauthorized access to the
data on the hard disk drive.
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 57.
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 64 alphabetic and numeric
characters. For more information, see “Password considerations.”
