SYSTEM CONFIGURATION

System Considerations

In Figure 3-6, no redundancy is shown in the Fusion link.

In this case, no redundancy is taken as to Fusion link.

3.1Fusion Network Conditions

This section explains how to design a Fusion network. In the following diagram, a Fusion Link is printed in a thick line while a CCIS link is printed in a dotted line.

Condition 1: The maximum number of nodes on a Fusion network is sixteen (16) nodes.
