C.2.5 External Battery
A connection for an external backup battery is provided at header J8, shown in Figure C-4.
The header is wired to provide reverse polarity protection.
Figure C-4. External Backup Battery Connection
The external battery connection is useful if the SRAM and real-time clock data need to be
preserved while the backup battery is being changed. This way power can continue to be
applied to the CPU Card from the backplane (if the external backup battery is being
replaced) or from the external battery (if the onboard backup battery needs to be changed
since this requires removing the CPU Card from the backplane in order to access the
onboard backup battery).
