Figure 3-4 Mixed Connection
The best use of the hub uplink is as a backbone connection to a 3Com
SuperStack II Switch 9300 Gigabit Ethernet switch, as shown earlier in
Figure 3-1 through Figure 3-2. Although two Hub 1000 SX units can be
connected to each other through their uplinks, as shown in Figure 3-5,
such a connection excludes connection to the network backbone.
