All redundant GBCs in the Secondary CPU redundant system MUST be configured at SBA 30. In our example, the rack level GBC is configured at SBA 30. The Bus level GBC is automatically configured at SBA 31

All of the Genius I/O blocks on the bus of a redundant GBC in a Hot Standby CPU

Redundancy system MUST be set Redundant.

Note

For fastest switching, all Genius Bus Controllers in the Hot Standby CPU Redundancy system should be in the main rack, or in a rack driven by the main rack's power supply. This will cause the Genius Bus Controller to lose power at the same time that the CPU loses power and allow the backup unit to gain full control of the I/O as soon as possible.
