Appendix B. REDUNDANT SYSTEMS

The CSAT-5060, 50 Watt C-Band Transceiver 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.
