Fast Ethernet Workgroup Design
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.
