The maximum allowable distance between the hub and a PC, server,
or other devices is 100 meters of Category 5 UTP cable. The UTP cable
used for hub-to-node connections is a straight-through connection. No
crossovers should be present.
Figure 2-1 shows a sample network configuration that implements
100BASE-TX Workgroup FastModules and CoreBuilder 5000 Switching
FastModules in the CoreBuilder 5000 hub.
A typical configuration for the 100BASE-TX Workgroup FastModule is
when you have a CoreBuilder 5000 7-slot hub running several 12-port
100BASE-TX Workgroup FastModules with a 100BASE-TX/FX
FastModule for a Fast Ethernet downlink connection over the
backplane.
