Fast Ethernet

Once the backbone switch has been selected, changes need to be made to the workgroups that will connect to the switch itself. As they stand, the current workgroups cannot connect to the Fast Ethernet backbone network. In order to support Fast Ethernet connections to the FN100-16FX, the MicroMMACs will require a BRIM. The Network Designer examines the available BRIMs that can be placed in the MicroMMAC-24Es. The BRIM-E100, when configured with the proper Fast Ethernet Interface Modules, will provide a Fast Ethernet uplink to the MicroMMAC-24Es. In order to support multimode fiber optic cabling, each of the six BRIM-E100s will be configured with two Fast Ethernet Interface Module-100FXs, providing 100BASE-FX connections. Once installed, the network will look like Figure 7-6.
