Model EN516/EN524 Ethernet Hub Installation Guide
You can cascade hubs together through any of the ports. 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 (or five paths).
