G.1 Resetting the Password Jumper
To disable the power-on or setup password features and clear the power-on and setup passwords:
1. Shut down the operating system and then turn off the workstation and any external devices. Disconnect the power
cord of the workstation and any external devices from the power outlets.
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 unit 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.
2. Open the access panel.
3. Locate the password header and jumper. The password header is E49.
NOTE: The password jumper is green so that it can be easily identified. For assistance locating the password jumper
and other system board components, refer to
4. Remove the jumper. Place the jumper on either pin 1 or 2 (not both).
5. Replace the access panel.
6. Plug in the workstation and turn on the power. Allow the operating system to start. This clears the current
passwords and disables the password features.
To establish new passwords, repeat steps 1 through 3, replace the password jumper on both pins 1 and 2, then
7.
repeat steps 5 through 7. Establish the new passwords in Computer Setup.
G.2 Clearing and Resetting the CMOS
The CMOS of the workstation stores password information and information about the workstation configuration. This
section describes the steps to successfully clear and reset the CMOS.
G.2.1 Using Computer Setup to Reset CMOS
To reset CMOS using Computer Setup, access the Computer Setup Utilities menu. When the Computer Setup message
appears in the lower-right corner of the screen, press the F10 key. Press Enter to bypass the title screen, if necessary.
NOTE: If you do not press the F10 key while the message is displayed, the workstation must be restarted to access the
utility.
From the Computer Setup menu, select File > Set Defaults and Exit. This restores the soft settings that include boot
sequence order and other factory settings. It does not, however, force hardware rediscovery.
NOTE: The workstation passwords and any special configurations along with the system date and time will have to be
reset.
G.2.2 Using the CMOS Button
CAUTION: Pushing the 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 the workstation CMOS settings
before resetting them in case they are needed later. To back up the CMOS settings, use Computer Setup and run the
Save to Diskette option from the File menu.
1. Shut down the operating system and then turn off the workstation and any external devices. Disconnect the power
cord of the workstation and any external devices from the power outlets. The CMOS will not clear if the
workstation remains connected to a power outlet.
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.
