1 INTRODUCTION
This section describes the features of the TEG-S40SX, as well as
giving 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 100Mbps
Fast Ethernet and a one hundred-fold increase over 10Mbps
Ethernet. Since it is compatible with all 10Mbps and 100Mbps
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 Switch User’s Guide
2 Introduction
Gigabit Ethernet enables fast optical fiber connections to support
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 able to perform 10 times the number of operations in the same
amount of time.
In addition, the phenomenal bandwidth delivered by Gigabit
Ethernet is the most cost-effective method to take advantage of
today and tomorrow’s rapidly improving switching and routing
internetworking technologies. And with expected advances in the
coming years in silicon technology and digital signal processing
that will enable Gigabit Ethernet to eventually operate over
unshielded twisted-pair (UTP) cabling, outfitting your network
with a powerful 1000Mbps-capable backbone/server connection
creates a flexible foundation for the next generation of network
technology products.
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

Gigabit Ethernet Switch User’s Guide
Introduction 3
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.
For Fast Ethernet or Gigabit 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, for example, 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 existing 10Mbps
networks and 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 and the setup and
maintenance required make routers relatively impractical. Today’s
switches are an ideal solution to most kinds of local area network
congestion problems.
Features
The TEG-S40SX Gigabit Ethernet Switch was designed for easy
installation and high performance in an environment where traffic
on the network and the number of users increase continuously.
Switch features include:

Unpacking
Open the shipping carton of the Switch and carefully unpack its
contents. The carton should contain the following items:
♦ One TEG-S40SX Gigabit Ethernet Switch
♦ Accessory pack: 2 mounting brackets and screws
♦ Four rubber feet with adhesive backing
♦ One AC power cord
♦ This user’s guide with Registration Card
♦ Diskette containing management software
If any item is found missing or damaged, please contact your local
reseller for replacement.

Unpacking and Setup 7
Setup
The setup of the Switch can be performed using the following
steps:
♦ The surface must support at least 3 kg.
♦ The power outlet should be within 1.82 meters (6 feet) of the
device.
♦ Visually inspect the power cord and see that it is secured
fully to the AC power connector.
♦ Make sure that there is proper heat dissipation from and
adequate ventilation around the Switch. Do not place heavy
objects on the Switch.
Desktop or Shelf Installation
When installing the Switch on a desktop or shelf, the rubber feet
included with the device must be first attached. Attach these
cushioning feet on the bottom at each corner of the device. Allow
enough ventilation space between the device and the objects
around it.

10 Unpacking and Setup
♦ The Power LED indicator will light while the Switch loads
onboard software and blinks when performing a self-test.
♦ The Console LED indicator will remain ON if there is a
connection at the RS-232 port, otherwise this LED indicator
is OFF.
Power Failure
As a precaution, the Switch should be unplugged in case of power
