Cache Battery Backup Option
3-18 DAC960PG Installation Guide
Cache Battery Backup Option
The optional cache battery backup provides temporary protection for
unwritten data in the controller’s cache memory in the event of a system
reset or power loss. Data maintained in the cache will be written to disk after
power is restored.
The optional cache battery backup module is available for the DAC960PG to
provide, in the event of a power failure, battery backup to the SIMM module
installed on the controller.
Battery Backup Module Connector
Connector J5 is available for the optional cache battery backup module. If
the optional cache battery backup module is not installed, the loop-back plug
must be present on connector J5 for proper controller operation.

WARNING
Be careful to observe proper orientation when
inserting a battery backup module or the loop-
back plug in connector J5. Check to make sure
that Pin 1 on the module corresponds to Pin 1 on
connector J5, and that all pins are mating properly
before full insertion. Improper insertion may
result in physical damage to the controller.
