Battery Backup
The AA-3102RS controller operates using cache memory. However,
when power failure occurs, the cache memory may contain buffered
data that has not yet been written to the hard disks. These buffered
data are not retrievable when power returns.
To avoid this from happening, a battery backup solution (AA-9070 and
AA-9010) is available to provide up to 100 hours of back-up time. The
AA-9070 is a battery backup daughter board that plugs into the
controller. The AA-9010 is a battery pack that connects to the AA-
9070 battery backup daughter board. Several AA-9010’s can be daisy
chained to provide long hours of unattended operation over a period of
days.
To install the battery backup daughter board and battery pack:
1. Make sure the power of the controller and drives are off.
