upper case) to refer to the 10-port 10/100/1000Mbps Gigabit Ethernet

Switch, and “switch” (first letter lower case) to refer to all Ethernet

switches, including the 10-port 10/100/1000Mbps Gigabit Ethernet

Switch.

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

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

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.

Features

The LevelOne GSW-2010T 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:

Ports

♦Two 10/100/1000Mbps Gigabit Ethernet port (port 9 ~ 10).

♦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.

♦256K bits packet buffer per device.

♦Supports broadcast storm rate filtering.

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.
