B.4 Redundant System Configuration
B.4.1 Initial Configuration
Redundant system configuration is controlled from the upconverter’s front panel configuration
menu. Each online unit is assigned a redundancy configuration address. This address is dependent
on the location of the online upconverter with reference to the backup. The unit closest to the
backup must be Upconverter # 1. The next unit down must be Upconverter # 2. Figure B-9
shows the appropriate entries for a 1:3 sy
stem.

Configure the online units first, and then configure the backup unit. Redundant polling starts
when the backup is configured. If this polling starts before the online units are configured, a high-
speed bus fault will result. This fault should clear when configuration is completed. At this point,
control of the redundant system is performed from the backup upconverter.
