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.

Figure 1-4. Interconnected Loop Configuration
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 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.
