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.
