180 ADDITIONAL PASSWORD SECURITY AND RESETTING CMOS
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.
2 Disconnect the keyboard, monitor, and any other external devices that are connected to the
workstation.
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, ensure that you are discharged of static electricity by
briefly touching a grounded metal object.
3 Remove the access panel.
4 Locate the header and jumper. The password jumper 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, see “System Board Components” on page 17.
5 Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so it does
not get lost.
6 Replace the access panel.
7 Reconnect the external equipment.
8 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.
9 To establish new passwords, repeat steps 1 through 4, replace the password jumper on pins 1 and 2,
then repeat steps 6 through 8. Establish the new passwords in Computer Setup.
