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 computer
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. Refer to “Motherboard” on page 25 .
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
improperly 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.
