AKING UB
You can connect hubs and hub stacks to the network backbone through
the transceiver interface module on the rear panel via a bridge, router, or
switch, using either Category 5 UTP or fiber cabling. Figure 3-6 shows
single and interconnected hubs connected to a network backbone.

Figure 3-6 Connecting Hubs to the Network Backbone
Two types of transceiver interface modules are available for connecting the
LinkBuilder FMS 100-TX Hub to the LAN. By inserting the appropriate
transceiver interface module in the hub's thirteenth port, you can use either
UTP or fiber-optic cabling to connect the hub to various LAN devices. For
example, you can connect the LinkBuilder FMS 100-TX Hub to a multiport
bridge or switch using the 100-TX module and gain access to a 10BASE-T
network. Likewise, by using the 100BASE-FX module, you can attach the hub
to a switch that is connected via fiber cabling to the network. (See the next
section for a discussion of using the hub to access multisegmented networks.)
The required cabling for the two transceiver interface modules is as follows:
100BASE-TX module: Category 5 two-pair UTP cabling
100BASE-FX module: two-strand 62.5/125 multimode fiber cabling
Connections to a server or PC from one of the transceiver interface modules
require straight-through cabling.
