Chapter 1 Product Overview
The CSM shuts down if the software failure or an external power failure occurs, or if the module is
separated from the backplane while it is still powered on. The CSM automatically backs up the data in
memory to the disk drives and then shuts down. The CSM batteries provide adequate power to back up
data without external power.
