I/O Remove Unit

2-10 Space Unit
2-11 I/O Remove Unit
File Memory Unit
Note
When a File Memory Unit is connected to the PC, contents of the Program
Memory and data areas can be transferred to and from File Memory (FM). For
details on operating the File Memory Unit, refer to the C1000H/C2000H Opera-
tion Manual.
The Unit can be mounted to either of the six rightmost slots on the Rack.
The Space Unit is included with the I/O Backplane to fill the space between the
Power Supply and the rightmost Unit mounted on the Backplane. This Unit only
applies to the I/O Backplane used in C2000H Duplex Systems. When mounting
this Unit be sure to remove the bracket on the Backplane first.
The I/O Remove Unit is unique to C2000H Systems. When mounted to a Rack of
a C2000H System, the I/O Remove Unit allows standard I/O Units to be removed
or mounted while the CPU is operating. The I/O Remove Units on each Rack are
connected by an I/O Remove Unit Connecting Cable.
In order to mount an I/O Unit to or remove an I/O Unit from any of the Racks in the
PC system, a Programming Console must be used to release the I/O Unit from
the control of the CPU. For details, refer to the PC Operation Manual.
Depending on the combination of I/O Units, a failed standard I/O Unit can be
replaced without affecting the other Units in the system.
When mounting or removing the I/O Units, the terminal block does not need to be
rewired. Simply mount the I/O Unit to the Backplane and then the terminal block
to the I/O Unit. When removing the I/O Unit, remove the terminal block first and
then remove the I/O Unit from the Backplane.
When an I/O Unit is mounted or removed while the CPU is operating on a Back-
plane which has an Interrupt Input Unit mounted to it, the Interrupt Input
(mounted only to C1000H and C2000H Simplex PCs) will be ignored.

units to be mounted or removed during operation. Even if none of the I/O
Units on the CPU Rack will be removed or mounted during operation, an I/O
Remove Unit is needed if I/O substitution is to take place on an Expansion
I/O Rack connected to the CPU Rack.
