The Expansion I/O Backplane shown in the following diagram, can be used to
expand the C1000H and C2000H Simplex and Duplex Systems. An Expansion
I/O Rack is just like a CPU Rack, except a CPU is not mounted. However, a
Power Supply is needed for each Expansion I/O Rack. There are three models
of Expansion I/O Backplane available. The Expansion I/O Rack shown below
can only be used with C2000H Systems. This Backplane has a special slot for
the I/O Remove Unit, which allows on-line I/O Unit exchange. two models are
available for C1000H PCs, with either five or eight slots.
I/O Remove Unit
When mounted to the Rack, I/O Units can be
removed or mounted while the PC is operating.
I/O Interface Unit
An I/O Interface Unit must be mounted to an Expansion
I/O Rack in order to connect the Expansion I/O Rack to
another Expansion I/O Rack.

Expansion I/O Backplane

Just as a Power Supply must be mounted to the CPU Rack, a Power Supply
must also be mounted to the I/O Backplane and Expansion I/O Backplanes.
There are two Power Supplies available; 100 to 120/200 to 240 VAC and 24
VDC, both of which are explained below. For details, refer to Appendix B Specifi-
cations. Either Power Supply can be used in the C1000H or C2000H Simplex
Systems; however, the 24-VDC Power Supply can not be used in the C2000H
Duplex System.

Note Be sure to keep the total power consumed by all the Units mounted on a Rack
within the value stated in the table above. For example, do not mount I/O Units
with a total current consumption of 7A to a Rack supplied by a 7 A Power Supply.
As shown in the table above, the available current for I/O Units is only 6.5 A. For
details concerning current consumption, refer to Section 4 System Connections.
