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.
