Cascade Configuration
Port 8, used in conjunction with the MDI/MDI-X switch, is the specified port
that allows you to connect one hub to another (cascade) or to connect to the
backbone using the same medium type. To cascade hubs, you should connect
Port 8 of the first hub to Ports 1-7 of the second hub and continue this scheme
for any additional hubs. The MDI/MDI-X switch for Port 8 of the first hub must
be set to the MDI position.
Figure 9 shows a cascaded topology using four hubs. Its design complies with
the four-repeater rule discussed in the next paragraph.
