Introduction
Thank you for choosing the 4-Port 10/100M NWay Ethernet Switch
Card. This Introduction chapter will be useful if you are new to Fast
Ethernet, Switch and other new technology featured by the 4-Port
10/100M NWay Ethernet Switch Card. Otherwise, skip ahead to the
Installation chapter.
About Fast Ethernet
Fast Ethernet is a network technology specified by IEEE Standard
802.3u. It extends the traditional 10Mbps Ethernet technology to
achieve 100Mbps transmission and reception, while retaining the
same CSMA/CD Ethernet protocol. Thus while Fast Ethernet
provides a tenfold increase in network capacity, it is wholly
compatible with traditional 10Mbps Ethernet network facilities. This
compatibility is the key to easy and efficient upgrades to 100Mbps in
your network areas needing greater bandwidth. Upgrading selected
areas to Fast Ethernet does not require hardware or software changes
in network areas where traditional 10Mbps Ethernet is providing good
service. For upgrading existing Ethernet installations to 100Mbps,
and especially for selectively upgrading areas needing upgrade, Fast
Ethernet is the clear choice in terms of cost-effectiveness, as well as
convenience and smoothness in transition.
Fast Ethernet comprises two subtypes: 100Base-T4 and 100Base-TX.
100Base-T4 Fast Ethernet can utilize existing Category 3 or Category
4 UTP network cabling, but does not provide for full duplex
operation. 100Base-TX requires Category 5 cabling, but does provide
full duplex operation. Full duplex 100Base-TX operation allows
simultaneous transmission and reception; both at 100Mbps, thus
providing service potentially equal to 200Mbps full-duplex service.
The 4-Port 10/100M NWay Ethernet Switch Card does not support
the 100Base-T4 subtype. To provide compatibility in traditional
1
10Mbps Ethernet environments, the 4-Port 10/100M NWay Ethernet
Switch Card also supports traditional 10Mbps Ethernet operation, in
full-duplex as well as half-duplex modes. Selection of the best
operation mode in any given installation is automatically governed by
auto-negotiation.
About Auto-negotiation
You have probably had the experience of making a dialup connection
through a modem, and have heard the gravelly−sounding exchanges
between your modem and the modem at the other end of the telephone
line (these exchanges are ordinarily played out through a speaker in
your local modem). As irritating as those few seconds of noise may
be, they do let you know that your modem and the remote modem are
on the job, preparing for your intended communication with the
remote computer.
The preparatory work of the two modems during those few seconds
before you see the “Connect” message is to negotiate the best data
communication scheme which is supported by both modems, and
which is suitable for the quality of the telephone line linkage between
them. The parameters to be settled between the two modems include
best baud rate, compression method, and error correction method.
When the two modems have tested the phone-line quality and settled
on the combination of shared options and parameters which will
provide the best data communication over the connecting phone line,
then you are given the ”Connect” message which signals the end of
the intermodem negotiation and the beginning of your intended
communication with the remote computer.
Auto-negotiation between devices within an Ethernet LAN is similar
in concept, but much briefer. The two devices involved in the autonegotiation will be the 4-Port 10/100M NWay Ethernet Switch Card
serving your station (installed in your computer), and the hub through
which it is connected into the LAN. The options to be negotiated
2
between the 4-Port 10/100M NWay Ethernet Switch Card and its
supporting hub include Ethernet type (100BASE-TX Fast Ethernet or
10BASE-T Ethernet) and duplex mode (half-duplex, being one-wayat-a-time, or full duplex, being simultaneous transmit-and-receive).
Startup communication between the two devices occurs when devices
are power-on, the cable connection between them is good, and the
Network Operating System software is running. As soon as those
conditions are satisfied, the preparatory process of auto-negotiation
between the 4-Port 10/100M NWay Ethernet Switch Card and its
supporting hub proceeds automatically. If the hub has autonegotiation functionality, then it and the 4-Port 10/100M NWay
Ethernet Switch Card exchange a series of messages in which each
device signals its capabilities and listens for corresponding
information about the other. The auto-negotiation process requires
only a few milliseconds, and the two devices select the best
communication parameters supported by both devices.
If the hub does not have auto-negotiation functionality, then its
monotone (single capability) message will be recognized by the 4-Port
10/100M NWay Ethernet Switch Card’s auto-negotiation facility, and
the 4-Port 10/100M NWay Ethernet Switch Card will simply switch
to the one of its own capabilities which matches that of the hub.
When the preparatory procedure of auto-negotiation is completed,
then the line is ready and will provide a data channel that is optimal
for the two devices. The line will remain ready without further autonegotiation action until the linkage is broken. Auto-negotiation then
reoccurs at any time that the linkage is restored, again making the line
ready for optimal data communications.

Switching Technology
Another approach to pushing beyond the limits of Ethernet technology
is the development of switching technology. A switch bridges
Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet or Fast Ethernet LAN
segments.
Switching is a cost-effective way of increasing the total network
capacity available to users on a local area network. A switch increases
capacity and decreases network loading by dividing a local area
network into different segments, which don’t compete with each other
for network transmission capacity.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with any other
segments, automatically forwards traffic that needs to go from one
segment to another. By doing this the total network capacity is
multiplied, while still maintaining the same network cabling and
adapter cards.
For Fast Ethernet Networks, a switch is an effective way of
eliminating problems of chaining hubs beyond the “two-repeater
limit.” A switch can be used to split parts of the network into different
collision domains, making it possible to expand your Fast Ethernet
Network beyond the 205-meter network diameter limit for 100BASETX networks. Switches supporting both traditional 10Mbps Ethernet
and 100Mbps Fast Ethernet are also ideal for bridging between the
existing 10Mbps networks and the new 100Mbps networks.
Switching LAN technology is a marked improvement over the
previous generation of network bridges, which were characterized by
higher latencies. Routers have also been used to segment local area
networks, but the cost of a router, the setup and maintenance required
make routers relatively impractical. Today switches are an ideal
solution to most kinds of local area network congestion problems.
