The rack assemblies contain an I/O backplane featuring edge connectors for
I/O modules and connectors for 24V system supply and 24V and 48V loop
power supplies. Input/Output modules connect to the I/O bus through four to
eight connectors on the backplane, depending on chassis style.
The backplane also contains ribbon cable connectors to interconnect chassis
assemblies and extend the I/O bus to the maximum number of modules
supported by the DPU.
