Network configuration (continued)
Connection 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 4100ES panel must contain the following:
•CPU
• System Power Supply
• 4100 Network Interface Card
• Optional slave cards
Network
communication
Network communication is achieved via the 4100-6014 Network Interface Card (NIC). 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.
