Network Configurations The installation of the EtheRx hub is simple and can be configured for either
the Ethernet Star topology, Linear Bus topology, or vertically stacked (SE
models only), 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
Cable Switch to support both cable types), a Straight-Through UTP cable
should be used. The physical network connection is illustrated in Figure 3-1.
