ABOUT THIS GUIDE

Congratulations on your purchase of the DGS-1224T 24-Port

10/100/1000Mbps Gigabit Ethernet+2-Port Mini GBIC Web Smart

Switch. This device integrates 1000Mbps Gigabit Ethernet, 100Mbps

Fast Ethernet and 10Mbps Ethernet network capabilities in a highly

flexible package.

Purpose

This guide discusses how to install and configure the DGS-1224T

Web Smart Switch.

Terms/Usage

In this guide, the term “Switch” (first letter upper case) refers to your

DGS-1224T Web Smart Switch, and “switch” (first letter lower case)

refers to other Ethernet switches.

INTRODUCTION

This chapter describes the features of the DGS-1224T and some

background information about Ethernet/Fast Ethernet/Gigabit Ethernet

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

guarantees cost-effective and high performance Fast Ethernet

solutions.

100Mbps Fast Ethernet is a 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.
