Chapter 4 Maintaining the Sun Fire X2250 Server 4-33
4.5.11 Replacing the System Battery
The system battery is a common CR2032 calculator battery.
You might need to replace the system battery if you know it is weak or if after any
period of AC power loss, the BIOS loses its CMOS settings, or if the time-of-day clock
loses time.
Caution – Removing the battery causes the server to revert to the factory default
BIOS settings, regardless of how the server boot options have been set up using the
System Setup Utility or the BIOS Setup utility.
Caution – Do not attempt to open or service batteries. The battery contains lithium
and can explode if not properly used, handled, or disposed of.

To remove the system battery:
1. Power off the system and remove the cover as described in Section 4.3,
“Powering Off the Server and Removing the Cover” on page 4-3.
2. If a PCI-Express card is installed in your server, remove the card as described in
Section 4.5.2, “Replacing the PCIe Card and Riser Assembly” on page 4-9.
3. Remove the system battery by gently pulling the clip away from the side of the
battery and sliding the battery out of the battery holder (see
