I/O Backplane

CPU Connectors
Connects the CPU Rack to the I/O
Rack. Use two connecting cables.
Expansion I/O Backplane Connector
Connects the I/O Rack to an Expansion
I/O Rack. When not used, cover with a
cap.
The I/O Backplane is always paired with the CPU Rack in a C2000H Duplex sys-
tem. The I/O Backplane houses the I/O Units, which cannot be mounted to the
CPU Rack. Use two cables to connect the I/O Backplane to the CPU Rack. Two
PC Link Units and one Host Link Unit can be mounted to any of the six rightmost
slots on the I/O Backplane. Similar to the C2000H CPU Backplane, the I/O Back-
plane also has a special slot for an I/O Remove Unit. Use one cable to connect
the I/O Remove Unit on the I/O Backplane to the I/O Remove Unit on the Expan-
sion I/O Rack.
I/O Remove Unit
When mounted to the Rack, I/O Units can be
removed or mounted while the PC is operating.
I/O Backplane I/O Units (8 Units max.)
I/O Control Unit
An I/O Control Unit must be mounted to
the I/O Backplane in order to connect the
I/O Backplane to Expansion I/O Racks.
