One I/O Interface Unit is needed on the Expansion CPU Rack and on each Ex-

pansion I/O Rack. Two models of I/O Interface Unit are available, the

CV500-II101 for the Expansion CPU Rack and the CV500-II201 for Expansion

I/O Racks. An I/O Interface Unit enable data communication between Racks.

The I/O Interface Unit must be mounted to the leftmost slot on the Expansion

CPU and Expansion I/O Backplane.
