module and I/O modules in a single 1746 chassis with a power supply.
You can configure a system with one, two, or three local chassis, for a maximum total of
30 local I/O or communication modules. You connect multiple local chassis together
with chassis interconnect cables to extend the backplane signal lines from one chassis to
another.
