24-Port Ethernet hub
Hubs can be interconnected to provide additional connections as
more switches (or other IBM managed products) are installed
on a network. Multiple hubs are daisy-chained by attaching RJ-45
Ethernet patch cables and configuring each hub through a medium-
dependent interface (MDI) switch.
Figure 2
illustrates the 24-port hub.
