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 (or five
paths).
The following illustration shows cascading Model EN308
daisy-chain style. Refer to the illustration for setting the Normal/Uplink push
button on each hub.
