Fast Ethernet Modules

Your Fast Ethernet segments connect to 3Com's
CoreBuilder 2500 system through Fast Ethernet
modules, which come with a copper or fiber
connector. This section describes the Fast Ethernet
modules, configurations possible for each module,
and how to connect the following modules to the
network:
100BASE-TX
100BASE-FX
Depending on your system configuration, your
system may support up to two Fast Ethernet ports.

100BASE-TX Module

This section contains a sample 100BASE-TX
configuration and information on configuring the
module.
100BASE-TX Configuration
Figure 4-17 illustrates a sample 100BASE-TX
configuration. Your configuration may have different
quantities and types of devices than pictured in this
example.
Figure 4-17 shows a Fast Ethernet module attached
to 3Com's SuperStack
configuration could be either 100BASE-TX (copper)
or 100BASE-FX (fiber).

Cabling the 100BASE-TX Module

The 100BASE-TX module offers one Fast Ethernet
port that uses an RJ-45 connector and provides a
100 Mbps Fast Ethernet connection over
UTP-Category 5 copper wire.
