1. Insert the male plug on one end of a standard 10BASE-T cable into one of the
RJ-45 female ports on the Hub’s front panel.
NOTE
Even though the Networking Hub’s connectors are shielded, they will
accept—and operate properly with—either unshielded or shielded RJ-45
twisted-pair cables. Use Category 3 cable or better.
2. Connect the other end of each network segment to a workstation or user
device. If the Networking Hub is getting AC power, it will light the Link/TX
LED corresponding to each Networking Hub port that has a powered-up and
functional device attached to it on the other end of the cable.
3.3 Cascading
You can cascade Networking Hubs in order to expand networks. For example, use
a 10BASE-T crossover cable to connect a Networking Hub’s RJ-45 port to any port
of another 10BASE-T hub, as shown in Figure 3-1. Since each Networking Hub
provides full repeater functionality, cascaded units can operate together even
though there may be a full segment of distance between them. To satisfy the “four-
repeater rule” defined by 10-Mbps Ethernet standards, you shouldn’t place more
than four 10BASE-T Ethernet hubs or repeaters in any path between two users on
the same Local Area Network (LAN).
