The CV-series CPUs have no I/O points built in. In order to complete the PC we

need to mount one or more Units providing I/O points to the Backplane. Mount

the Units to the Backplane by pressing them firmly into position, making sure the

connectors are properly mated. Secure the Unit by tightening the mounting

screws located on the top and bottom of the Unit.

Mounting screws

Provided at the top and

bottom of the Unit.

Connector

Make sure the connectors

are properly mated.

The following figure shows one I/O Unit mounted directly to the left of the CPU.

Units other than the Power Supply Unit, the CPU, and the I/O Control Unit (see

below) can be mounted to any of the other slots on the CPU Rack.

I/O Unit

As you can see from the figure, there is still some space available to the left of the

I/O Unit. This space is for any additional Units that may be required.

The figure above shows a total of ten I/O Units mounted to the Backplane. These

I/O Units could be replaced by other Units, such as Special I/O Units, CPU Bus

Units, etc. I/O Units come in five shapes; A-, B-, C-, D- and E-shape (refer to

Ap-

pendix B Specifications) each of which can be mounted to any of the ten slots.

The Backplane, Power Supply Unit, CPU, and other Units are collectively called

a CPU Rack.
