Password security
The power-on password prevents unauthorized use of the workstation by requiring entry of a password
to access applications or data when the workstation is powered on or restarted. The setup password
specifically prevents unauthorized access to the Computer Setup (F10) Utility and can also override the
power-on password. When prompted for the power-on password, entering the setup password instead
enables access to the workstation.
You can establish a network-wide setup password, which lets the system administrator log in to all
network systems to perform maintenance without having to know the power-on password.
Establishing a setup password using Computer Setup (F10) Utility
Establishing a setup password through the Computer Setup (F10) Utility prevents reconfiguration of the
workstation (through the use of the Computer Setup (F10) Utility) until the password is entered.
To establish a setup password using the Computer Setup (F10) menu:
1. Power on or restart the workstation.
2. As soon as the workstation is powered on, press and hold F10 until you enter the Computer Setup
(F10) Utility. Press Enter to bypass the title screen, if necessary.
If you do not press F10 at the appropriate time, you must restart the workstation, and then press
and hold F10 again to access the utility.
If you are using a PS/2 keyboard, you might see a keyboard error message. Disregard it.
3. Select Security>Setup Password and then follow the onscreen instructions.
4. Before exiting, select File>Save Changes and Exit.
