INTRODUCTION
This section describes the features of the LevelOne GSW-2010T
Switch , as well as giving some background information about Gigabit
Ethernet, Fast 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 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
3
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 1000-Mbps-
capable backbone/server connection creates a flexible foundation for
the next generation of network technology products.
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 other 10Mbps Ethernet
4
environments, it provides a straightforward upgrade and takes
advantage of the existing investment in hardware, software, and
personnel training.
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 an
ideal solution to most kinds of local area network congestion
problems.

♦Eight 10/100Mbps Fast Ethernet ports (port 1 ~ 8).
Performance features
♦Store and forward switching scheme capability to support rate
adaptation and protocol conversion.
♦Full duplex to allow two communicating stations to transmit
and receive at the same time.
♦Wire-speed data forwarding rate for each port.
♦Wire-speed data filtering rate for each port.
♦6K active MAC address entry table per device with automatic
learning and aging.

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 8 port Fast Ethernet Switch with Two Gigabit port
♦Four rubber feet with adhesive backing
♦One AC power cord
♦This User’s Guide
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:
♦The surface must support at least 5 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.
