Chapter 7 Module Overview and Specifications
The bus and power connections from the processor base unit go into the
backplane at the left connector and are routed direct to the module
connectors. The backplane has a connector at the right for the next I/O
backplane. The connection to the left of the backplane can connect to a
processor base unit or another I/O base unit.
Adjacent base units clip together and are held in position by a plastic retaining
clip. Alternatively rows of I/O base units can be connected together using a
T9310 expansion cable assembly.
