INTRODUCTION
This section describes the features of the Switch, as well
as providing some background information about Gigabit
Ethernet and switching technology.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet
utilizing the same packet structure, format, and support
for CSMA/CD protocol, full duplex, flow control, and
management objects, but with a tenfold increase in
theoretical throughput over 100-Mbps Fast Ethernet and
a hundredfold increase over 10-Mbps Ethernet. Since it is
compatible with all 10-Mbps and 100-Mbps Ethernet
environments, Gigabit Ethernet provides a
straightforward upgrade without wasting a company’s
existing investment in hardware, software, and trained
personnel.
The increased speed and extra bandwidth offered by
Gigabit Ethernet is essential to coping with the network
bottlenecks that frequently develop as computers and
their busses get faster and more users use applications
that generate more traffic. Upgrading key components,
such as your backbone and servers to Gigabit Ethernet
can greatly improve network response times as well as
significantly speed up the traffic between your subnets.
Gigabit Ethernet supports video conferencing, complex
imaging, and similar data-intensive applications. Likewise,
since data transfers occur 10 times faster than Fast
Ethernet, servers outfitted with Gigabit Ethernet NIC’s are
English

able to perform 10 times the number of operations in the
same amount of time.
Switching Technology
Another key development pushing the limits of Ethernet
technology is in the field 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 making it possible for a local area
network to be divided into different segments which don’t
compete with each other for network transmission
capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge
between the individual segments. Traffic that needs to go
from one segment to another is automatically forwarded
by the switch, without interfering with any other segments.
This allows the total network capacity to be multiplied,
while still maintaining the same network cabling and
adapter cards.
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 and the setup and maintenance required
make routers relatively impractical. Today’s switches are
English

an ideal solution to most kinds of local area network
congestion problems.
Features
The Switch was designed for easy installation and high
performance in an environment where traffic on the
network and the number of users increase continuously.

UNPACKING AND SETUP
This chapter provides unpacking and setup information for the
Switch.
Unpacking
Open the shipping carton of the Switch and carefully unpack its
contents. The carton should contain the following items:
One Gigabit Switch
Four rubber feet with adhesive backing
One external power adapter
This User Manual
If any item is found missing or damaged, please contact your
local reseller for replacement.
Setup
The setup of the Switch can be performed using the following
steps:
Install the Switch in a fairly cool and dry place. See
Technical Specification for the acceptable operation
temerature 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.
