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.
