Network Configuration, Continued

Connecting Loops	Network loops can be joined via physical bridge cards. There may be no more than two
	Style 7 network loops (two hub configurations) connected in tandem. For every two
	loops that are interconnected (using one physical bridge), there can be a maximum of
	three physical bridges used in a star configuration. See Figure 1-4.

System Design
	To be used as a network node, a 4100 panel must contain the following:
	•	CPU
	•	System Power Supply
	• 4100 Network Interface Card
	•	Optional slave cards

Network Communication

Network communication is achieved via 4100-6014 or 4100-6035 Network Interface Cards (NICs). Each network node requires a NIC. Once the FACP is a network node, it may be programmed to be fully in control of other nodes, or to be fully passive, or anywhere in between.
