Replacing the Battery
All motherboards use a battery to maintain system configuration information. If it fails
to maintain system configuration, replace it with an identically rated battery from the
same manufacturer.
Replace the battery as described below:
Caution
Removing the battery from the motherboard causes the com-
puter to lose system configuration information. Before removing
it, run Setup and record the system configuration settings.
Use this information to restore the system after replacing the
battery.
1. Turn off and unplug the system unit and any external options connected to the
system.
2. Open the server chassis.
3. Locate the battery on the motherboard. See “
Motherboard” on page 34.
4. Use your finger to carefully remove the battery from the battery socket on the
motherboard.
Warning
The battery may explode if it is incorrectly replaced or improp-
erly discarded.
Use only an identically rated battery from the same
manufacturer.
5. With the positive (+) side facing up, press the new battery into the socket.
6. Close the server chassis.
7. Connect the external peripherals and the power cables.
8. Run Setup to reconfigure system parameters.
