Installation Guide for the Model EN516 Ethernet Hub
3-6 Installation
Cascading refers to connecting hubs together to increase the number of ports, or the number of
users supported on the network. The RJ-45, BNC, or AUI ports can be used to cascade hubs
together. Figure 3-3 illustrates multiple hubs cascaded in a hierarchical star.

Note:
Ethernet specifications limit the number of hubs in any communication path to five
hubs, as shown in Figure 3-3. For example, when PC “A” communicates with PC “B,” the
communication path goes from hub 5 to hub 7, passing through hubs 2, 1, and 4.
