Figure B-1. Referencing I/O Slots Outside the Host
Notes:
 I/O racks that are part of a redundant pair share the same slot
numbers.
 The address tables cover slot numbers up through 14. If you have
multiple non-redundant I/O racks attached to the same host
ControlWave, use consecutive I/O slot numbers for each successive
rack, as if it was the part of the host ControlWave. Mapping
addresses follow the same pattern for the higher slots.
