Clearing Configuration Memory
The workstation’s configuration memory (CMOS) may occasionally be
corrupted. When this occurs, it is usually due to software or hardware that is not
functioning accurately, or due to the addition or removal of expansion boards.
If the workstation’s configuration memory becomes corrupted, it is necessary to
clear the configuration memory.
1. Turn off the workstation and any external devices, and disconnect the
power cord from the grounded AC outlet.
2. Disconnect the keyboard, monitor, network cable, and any other external
devices connected to the workstation.
WARNING: To reduce the risk of personal injury from electrical
shock and/or 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 unit is plugged in, the power supply
always has 5 volts 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 computer or optional equipment. Before
beginning these procedures, ensure that you are discharged of
static electricity by briefly touching a grounded metal object.
Refer to Appendix B of this guide for more information.
3. Remove the workstation access panel. See the “Removing the
Workstation Access Panel” section in Chapter 4.
