Lithium Battery
The battery that comes with your workstation provides power to the real-time clock and has a
life of about five years. When replacing the battery, use a CR2032 or equivalent 3-volt lithium
coin cell battery.
1. Turn off the workstation and any external devices. Disconnect the power cord from the
grounded AC outlet. Disconnect the network cable and any external devices from the
system. Remove the side access panel.
IMPORTANT:
On a power-managed system, the power cord must be disconnected from the grounded
AC outlet.
NOTE:
It may be necessary to remove an expansion board to gain access to the battery.
