Bridging from 10BASE-T to 100BASE-TX Networks

The BayStack 70 Series 10/100 Ethernet Switch can function as a two-port bridge connecting traditional 10BASE-T Ethernet networks to 100BASE-TX Fast Ethernet networks. Users requiring increased network bandwidth can be upgraded to 100 Mb/s while remaining connected to the rest of the network. Figure 2-4 illustrates a BayStack 70-8T 10/100 Ethernet Switch and a BayStack 70-16T 10/ 100 Ethernet Switch connected by a BayStack 70-24T 10/100 Ethernet Switch, as well as attached to several other network and end station devices.
