There are two types of Backplane: the CPU Backplane, used for the CPU Rack,
and the I/O Backplane, used for Expansion I/O Racks. The Backplane serves to
hold and connect the following types of Unit: the CPU Unit, the Power Supply
Unit, I/O Units, Special I/O Units, etc.
The components of the Backplanes are shown in the following diagrams and
described following them. The numbers in the diagram correspond to the num-
bers of the following items in the description.
