10 Network Configurations

Network Configurations

The installation of the EtheRx hub is simple and can be configured for either the Ethernet Star topology or Linear Bus topology. The hubs may also be vertically stacked or horizontally cascaded to other Ethernet hubs. For cascading, please observe the Ethernet 5-4-3 Rule.

Ethernet 5-4-3 Rule

The Ethernet 5-4-3 rule states that the maximum transmission path permitted between any two stations is:

•5 segments

•4 repeater sets

•3 coax segments. The remaining 2 segments may be linked segments

Ethernet Star Network

The typical network configuration for 10BASE-T Ethernet is a Star Topology, in which nodes are connected to a central Ethernet hub. Since a Crossover function is implemented on all ports (except the last UTP port which uses a cascade switch to support both cable types), a straight-thru UTP cable should be used. The physical network connection is illustrated in Figure 4.
