The workstation configuration memory (CMOS) may occasionally be corrupted. When this
occurs, it is usually due to software or hardware that is not functioning accurately, or to the
addition or removal of expansion boards. If the workstation configuration memory becomes
corrupted, it is necessary to clear the configuration memory.
1.
Turn off the workstation and any external devices, then disconnect the power cord from
the back of the workstation and 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 electric 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 them.
CAUTION:
Before removing the side access panel, ensure that the workstation is turned off, all
cables are disconnected from the back of the workstation, and the power cord is disconnected
from the grounded AC outlet.
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.
3.
Remove the side access panel to access the system board.
