7 Configuring password security and resetting CMOS This chapter describes how to configure password security and to reset CMOS, and includes these topics: ● Preparing to configure passwords on page 141 ● Clearing and resetting workstation passwords on page 141 ● Clearing and Resetting the CMOS on page 142 Preparing to configure passwords The Computer Setup (F10) Utility enables you to create setup and power-on passwords. When you create a setup password, only the power-on password is required to access the Computer Setup (F10) Utility and any other information on the workstation. When you create both passwords, only the setup password gives you access to the Computer Setup (F10) Utility. When both passwords are created, the setup password can also be used in place of the power-on password as an override to log into the workstation (a useful feature for a network administrator). If you forget a password, two methods are available for clearing the password to gain access to the information on the workstation: ● Reset the password jumper ● Press the Clear CMOS button CAUTION: Pressing the Clear CMOS button resets CMOS values to factory defaults and erases any customized information, including passwords, asset numbers, and special settings. It is important to back up your workstation CMOS settings before resetting them in case they are necessary later. To back up the CMOS settings, run the Computer Setup (F10) Utility and select Save to Diskette from the File menu. Clearing and resetting workstation passwords To disable the power-on or setup password features and clear the power-on and setup passwords: WARNING! To reduce the risk of personal injury from electrical shock and hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system components to cool before touching. CAUTION: When the workstation is plugged in, the power supply always has voltage applied to the system board even when the workstation is turned off. Failure to disconnect the power cord can result in damage to the system. CAUTION: Static electricity can damage the electronic components of the workstation or optional equipment. Before beginning these procedures, be sure that you are discharged of static electricity by briefly touching a grounded metal object. ENWW Preparing to configure passwords 141

Preparing to configure passwords
The Computer Setup (F10) Utility enables you to create setup and power-on passwords.
When you create a setup password, only the power-on password is required to access the Computer
Setup (F10) Utility and any other information on the workstation. When you create both passwords, only
the setup password gives you access to the Computer Setup (F10) Utility.
When both passwords are created, the setup password can also be used in place of the power-on
password as an override to log into the workstation (a useful feature for a network administrator).
If you forget a password, two methods are available for clearing the password to gain access to the
information on the workstation:
●
Reset the password jumper
●
Press the
Clear CMOS
button
CAUTION:
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases any
customized information, including passwords, asset numbers, and special settings. It is important to
back up your workstation CMOS settings before resetting them in case they are necessary later. To
back up the CMOS settings, run the Computer Setup (F10) Utility and select
Save to Diskette
from the
File menu.
Clearing and resetting workstation passwords
To disable the power-on or setup password features and clear the power-on and setup passwords:
WARNING!
To reduce the risk of personal injury from electrical shock and hot surfaces, be sure to
disconnect the power cord from the wall outlet and allow the internal system components to cool before
touching.
CAUTION:
When the workstation is plugged in, the power supply always has voltage applied to the
system board even when the workstation is turned off. Failure to disconnect the power cord can result
in damage to the system.
CAUTION:
Static electricity can damage the electronic components of the workstation or optional
equipment. Before beginning these procedures, be sure that you are discharged of static electricity by
briefly touching a grounded metal object.
