Resetting the password jumper
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.
1. Shut down the operating system, and then power off the workstation and any external devices.
Disconnect the workstation power cord and any external devices from the power outlets.
2. Disconnect the keyboard, monitor, and any other external devices that are connected to the
workstation.
3. Remove the access panel.
4. Locate the password header and jumper. The password header is E49.
NOTE: Ensure that the AC power cord is disconnected from the power outlet. The CMOS button
does not clear CMOS if the power cord is connected.
The password jumper is green so that it can be easily identified. For assistance locating the
password jumper and other system board components, see the service label located on the inside
of the workstation access panel, or see
System board components on page 59.
.
5. Remove the jumper from either pin 1 or 2. Place the jumper on pins 1 and 2 (connecting both pins
together).
6. Replace the access panel.
7. Reconnect the external equipment.
8. Plug in and power on the workstation. Allow the operating system to start. This process clears the
current passwords and disables the password features.
9. To establish new passwords, repeat steps 1 through 4, replace the password jumper on either pin
1 or pin 2 (but not both), and repeat steps 6 through 8. Establish the new passwords using the
Computer Setup (F10) Utility.
