ETWORK
The 7-port 100BASE-FX/TX FastModule provides seven switched Fast
Ethernet connections to any one of four CoreBuilder 5000 FastChannel
backplane networks. When used in conjunction with other
CoreBuilder 5000 FastModules, this FastModule lets you create
backbone and floor configurations based on shared and switched Fast
Ethernet and Ethernet. The 100BASE-TX ports on the 7-port
FastModule using RJ-45 connectors can be used to provide dedicated
100 Mbps connections to workgroup servers
Users are connected to each of the 12 ports on the 100BASE-TX
Workgroup FastModule distributed among the four Fast Ethernet
channels. These channels are aggregated and downlinked through the
switching 100BASE-TX/FX FastModule in the CoreBuilder 5000 hub.
For more information on switching fast modules, refer to the
CoreBuilder 5000 FastModule User Guide.
