182 ADDITIONAL PASSWORD SECURITY AND RESETTING CMOS
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.
3 Remove the access panel.
4 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 Components” on page 69.
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 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 either pin 1 or pin 2 (but 
not both), then repeat steps 6 through 8. Establish the new passwords in Computer Setup.
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.
Using the CMOS Button
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.
