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 local area networks (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-TX
(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 Switch is compatible with all 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 bridges and transmits Ethernet packets at the MAC
address level of the Ethernet protocol, 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.
Each segment has its own bandwidth and it does not
compete with others for network transmission capacity.
A switch acts as a high-speed selective bridge between the
individual segments. The switch forwards traffic from origin
segment to destination segment, without interfering with
any other segments. 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 to
eliminate problems of uplinking Fast Ethernet 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. The switch supports
both traditional 10Mbps Ethernet and 100Mbps Fast
Ethernet, which is also ideal for bridging between the
existing 10Mbps networks and the new 100Mbps networks.
LAN switching technology is a significant improvement
over the previous generation of network bridges, which
were criticized because of their higher latencies. Routers are
also used to segment LANs. However, since routers are
expensive, difficult to setup, and require intensive
maintenance, they are relatively impractical for the
network. Switches, on the other hand, are less expensive,
easier to set up, and practically maintenance free, which
make them an ideal solution to today's LAN congestion

problems.
Features
This high-performance Switch was designed for a network
environment where traffic and the number of users increase
continuously.
The Switch, with their small, desktop size, was specifically
designed for small to middle-sized workgroups. It provides
immediate access to a rapidly growing network through a
wide range of user-reliable functions.
The Switch is ideal for shared bandwidth 10Mbps or
100Mbps workgroups with multiple high-speed servers.
With the highest bandwidth at 200 Mbps (100 Mbps full-
duplex mode), each port can provide workstation with
congestion-free data-pipe for simultaneous access to the
server.
The Switch is expandable by cascading two or more
switches together. Since all ports support 200 Mbps, the
Switch can be cascaded from any port and to any number of
switches.
The Switch is a perfect choice for a 10Mbps network site that
might be upgraded to Fast Ethernet in the future. Ethernet
workgroups can connect to the Switch now, and change
adapters and hubs anytime later without changing the
Switch or reconfiguring the network.
The Switch combines dynamic memory allocation with
store-and-forward switching method to ensure that the
buffer is effectively allocated for each port. It also controls
the data flow between transmit and receive nodes to
guarantee against all possible packet loss.

Installation
The site where you install the Switch may greatly affect its
performance. When installing, consider the following
pointers:
•Install the Switch in a fairly cool and dry place. See
Technical Specification for the acceptable operating
temperature and humidity ranges.
•Install the Switch in a site free from strong
electromagnetic source, vibration, dust, and direct
sunlight.
•Leave at least 10cm of space at the left and right hand
side of the Switch for ventilation.
•Visually inspect the DC power jack and make sure that
it is fully secured to the power adapter.
External Components
This section identifies all the major external components of
the switch. Both the front and rear panel is shown, followed

With the Auto-MDI function, you just need to plug-in the
network cable to the hub directly and no need to care if the
end node is NIC (Network Interface Card) or switches and
hubs.
DC Power Jack
Power is supplied through an external AC power adapter.
Check the technical specification section for information
about the AC power input voltage.
Since the switch does not include a power switch,
plugging its power adapter into a power outlet
will immediately power it on.
