The bus and power connections from the processor base unit enter the backplane at
the left connector and are routed direct to the module connectors. The backplane
provides 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.
