Redundant Controller Communication Channel: this field is set for display only

Seccondary Controller RS-232 Terminal: In a redundant controller configuration, the RS-232C port on the secondary controller is normally unfunctional. Enable this function if you wish to use the port for debug purpose.

Cache Synchronization on Write-Through: If controllers are operating using the Write-Through caching mode, the Synchronized cache operation can be manually disabled to save system resources for better performance.
Note that if sync. cache is disabled, the configuration changes made through the primary controller henceforward will no longer be mirrored to the secondary controller.
