B.4 Configuring A Redundant System .........................B-9
The CSAT-6070, 5 to 25 Watt C-Band Tranceiver, is capable of operating in both stand-alone
and redundant configurations. The CSAT fully redundant system provides automatic detection,
switching, and status for both its configuration and health. The system is designed such that
stand-alone operation is a functional sub-set of the fully redundant CSAT system. This provides
the user with transparent functionality regardless of the mode or complexity the system has been
setup to operate in.
