ABOUT THIS GUIDE
Congratulations on your purchase of the 5/8-port
10/100M NWay Fast Ethernet Switch. This device
integrates 100Mbps Fast Ethernet and 10Mbps
Ethernet network capabilities in a highly flexible
desktop package.
Purpose
This manual discusses how to install your 5/8-port
10/100M NWay Fast Ethernet Switch.
Terms/Usage
In this guide, the term “Switch” (first letter upper
case) refers to your 5/8-port 10/100M NWay Fast
Ethernet Switch, and ”switch” (first letter lower case)
refers to other Ethernet switches.
This guide provides the information you need to install
and configure the following models of the Switch:
§5-port 10/100M NWay Fast Ethernet Switch
§8-port 10/100M NWay Fast Ethernet Switch
The functionality of both units is identical, except for
the number of ports. Where appropriate, differences
between the two units are noted.

INTRODUCTION
This chapter describes the features of the Switch and
some background information about Ethernet/Fast
Ethernet switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing
complexity of desktop computing applications are
fueling the need for high performance networks. A
number of high-speed LAN technologies have been
proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-
T (Fast Ethernet) provides a non-disruptive, smooth
evolution from the current 10BASE-T technology. The
non-disruptive and smooth evolution nature, and the
dominating potential market base, virtually guarantee
cost effective and high performance Fast Ethernet
solutions in the years to come.
100Mbps Fast Ethernet is a new standard specified by
the IEEE 802.3 LAN committee. It is an extension of
the 10Mbps Ethernet standard with the ability to
transmit and receive data at 100Mbps, while
maintaining the CSMA/CD Ethernet protocol. Since
the 100Mbps Fast Ethernet is compatible with all
2
other 10Mbps Ethernet environments, it provides a
straightforward upgrade and takes advantage of the
existing investment in hardware, software, and
personnel training.
Switching Technology
Another approach to pushing beyond the limits of
Ethernet technology is the development of switching
technology. A switch bridge 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 100BASE-TX 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.

Features
The Switches were designed for easy installation and
high performance in an environment where traffic on
the network and the number of user increase
continuously.
The Switches with their small, compact size were
specifically designed for small to middle workgroups.
These Switches can be installed where space is
limited; moreover, they provide immediate access to a
rapidly growing network through a wide range of user-
reliable functions.
The Switches are ideal for deployment with multiple
high-speed servers for shared bandwidth 10Mbps or
100Mbps workgroups. With the highest bandwidth
200Mbps (100Mbps full-duplex mode), any port can
provide workstations with a congestion-free data pipe
for simultaneous access to the server.
The Switches are expandable by cascading two or
more switches together. As all ports support
200Mbps, the Switches can be cascaded from any port
and to any number of switches.
The Switches are a perfect choice for site planning to
upgrade to Fast Ethernet in the future. Ethernet
