3-18 Configuring the Hub

Using the STP Cascade Connector

By default, all ports on an STP media module are physically configured as M
ports. If you want to configure the module for a B/A or S/M connection, you
must use one or two STP cascade connectors to allow the new configuration.
(The STP cascade connector gets its name from its use in connecting a series of
rack-mounted hubs in which the connecting cascade cables "flow" from one hub
down to the next.)
Figure 3-7 shows two STP cascade connectors installed on an STP module to
allow dual attachment configuration.
