Installation and Reference for the BayStack 60-12T/60-24T 10/100 Ethernet Hubs

Figure 2-3 shows the specific ports used to connect two hubs, as in the expanded network in Figure 2-2. Port 1 on the top hub is set to MDI (uplink) with the MDI/ MDI-X button. A UTP/STP Ethernet cable connects port 1 of the top hub to another non-MDI port on the second hub. This type of connection is known as “daisy-chaining.”

Bridging

The internal switching hardware of the hub bridges the two collision domains, the 10 Mb/s and 100 Mb/s segments. The switching hardware handles the bridging, which allows 10 Mb/s and 100 Mb/s segments to talk to each other.
