Cascade the Hub
The following illustration shows cascading hubs together in a hierarchical star
through the 10BASE-T ports and indicates the setting of the Normal/Uplink
push button on each hub.
The following illustration shows cascading hubs together daisy-chain style and
indicates the setting of the Normal/Uplink push button on each hub.
Note: Ethernet specifications limit the number of hubs with twisted
pair links in any communication path to five, as shown in the example.
When PC “A” communicates with PC “B,” the communication path
goes from hub 4 to hub 2, to hub 1, to hub 3, and then to hub 5.
