4.3 Fast Ethernet
100Base-TX and 100Base-FX are called "Fast Ethernet." This
is because they use the Ethernet CSMA/CD access rules and
data packet structure, but data travels ten times faster
(100Mbps) than traditional 10Mbps Ethernet.
Below is a list of the cable types and connectors that supported
by
NovaSwitch models for 10Base-T, 100Base-TX, and
100Base-FX networks.

In many cases, 10Base-T LANs can quickly and easily upgrade
to 100Base-TX networks.
4.4 Auto-Negotiation
The 100Base-TX ports on the NovaSwitch have built-in
"Auto-Negotiation". This technology automatically sets the best
possible bandwidth when a connection is established with
another network device (usually at Power On or Reset). This is
done by detect the mode and speed at the second device is
capable of. The 100Base-TX devices can connect with the
100Base-TX port in either Half- or Full-Duplex mode.
If attached device is: 100Base-TX port will set to:
100Mbps, no auto-negotiation 100Mbps
(100Base-TX, Half-Duplex)
100Mbps, with auto-negotiation 200Mbps
(100Base-TX, Full-Duplex)
10Mbps, no auto-negotiation 10Mbps
(10Base-T, Half-Duplex)
