Clearing and Resetting the CMOS, Using the CMOS Button

Page 174 highlights

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 J64. 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 67. 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. 174 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 J64.
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 67
.
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.

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.
