1.3 RCI Connection Scheme
• Cluster configuration
Figure 1.2 shows a cluster connection pattern.
Figure 1.2 Cluster connections
Up to 32 RCI hosts can be connected.
The cluster connection requirements, such as the maximum cable length and the
number of connectable RCI I/O units, are the same as the basic configuration
requirements.
Note: The repeater function of the external power controller cannot be used to
increase the number of RCI base cabinets.
• Duplicated configuration
Figure 1.3 shows the connection pattern of a duplicated configuration.
Figure 1.3 Duplicated configuration
RCI hosts can be constructed in a duplicated configuration only if their XSCF units
are in a redundant configuration (duplicated configuration).
Note: Do not connect an expansion XSCF unit to an RCI network connected to a
base XSCF unit.
