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.Remove 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 “System Board” on page 80.

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.

7.To establish new passwords, repeat steps 1 through 3, replace the password jumper on both pins 1 and 2, then repeat steps 5 through 7. Establish the new passwords in Computer Setup.
