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.
Caution –
Do not attempt to open or service batteries. The battery contains lithium
and can explode if not properly used, handled, or disposed of.
