Network Configuration, Continued
Network rings or loops can be joined via physical bridge cards. There may be no more
than two network loops connected in tandem. For every two loops that are
interconnected (using one physical bridge), there can be a maximum of three other
physical bridges used in a star configuration. See Figure 3-2.{xe "Network 4100 Fire
Alarm System: physical bridge (overview)"}{xe "physical bridge: connecting loops
with"}{xe "Network 4100 Fire Alarm System: loops"}
