To find out how to install the software and configure it for UPS operation, refer to the
manual "Reliant UNIX Installation and Operation – RM200, RM300, RM400" or to
the corresponding manual for SINIX V5.42.

5.1.9

Using the battery backup unit (BBU)

The RM400-C80/90 models are not equipped with a BBU. We recomn-
i
mend that you use a UPS for these systems.
The system can optionally be shipped with a battery backup unit (BBU). The pur-
pose of the BBU is to bridge brief power outages or to maintain the supply of power
to the system in the event of an extended line power failure until the system can be
shut down gracefully. In this way loss of data can be prevented in spite of a power
outage.
If you want to add a BBU to your system at a later date, you must have the work done
by SNI Service.
The life of the BBU's battery is about four years. To guarantee operational
i
reliability, the battery must be replaced every four years.
