Preparing to configure passwords

The Computer Setup (F10) Utility enables you to create setup and power-on passwords.
There are three possibilities for setting passwords:
Define a setup password only. You will need the password to enter Computer Setup (F10) Utility, but you

will not need a password to start the workstation.
● Define a power-on password only. This password lets you start the workstation or enter the setup utility.
● Define both. In this case, the setup password lets you start the workstation and enter the setup utility.
The power-on password starts the workstation but does not let you enter the setup utility,
After you create both passwords, you can use the setup password in place of the power-on password as an
override to log in to the computer (a useful feature for a network administrator).
NOTE: You can only clear the passwords with the password jumper. Clearing CMOS does not clear the
passwords.
CAUTION: Before pressing the Clear CMOS button, back up your computer CMOS settings.
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized information,
including asset numbers and special settings.
To back up the CMOS settings, run the Computer Setup (F10) Utility and select File>Replicated Setup>Save
to Removable Storage Device.
