    BOUT UIDE Congratulations on your purchase of the DES-1024D 24-port 10/100Mbps Fast Ethernet Switch. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities into one highly flexible solution. Purpose This guide discusses how to install your DES-1024D. Terms/Usage In this guide, the term “Switch”...

  • Page 4: Introduction

    NTRODUCTION This chapter describes the features of the DES-1024D and some background information about Ethernet/Fast Ethernet switching technology. Fast Ethernet Technology Ethernet, along with its speedier counterpart Fast Ethernet, is the most popular networking standard in use today. 100BaseT Fast Ethernet is an extension of the 10BaseT Ethernet standard, designed to raise the data transmission capacity of 10BaseT from 10Mbits/sec to 100Mbits/sec.

  • Page 5: Switching Technology

    Switching Technology Switching is a cost-effective way of increasing the total network capacity available to users on a LAN. If an Ethernet network begins to display symptoms of congestion, low throughput, slow response times, and high rates of collision, installing a switch to an network can preserve much or all of the existing network's cabling and workstation interface card infrastructure while still greatly enhancing the throughput for users.

    latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup and maintenance required make routers relatively impractical. Today switches are an ideal solution to most kinds of local area network congestion problems. Features The DES-1024D is a high-performance switch designed specifically for environments where traffic on the network and the number of users increase...

  • Page 7: Priority Queues

    The implementation of QoS (Quality of Service) and benefits of using 802.1p priority queuing are described here. Advantages of QoS QoS is an implementation of the IEEE 802.1p standard that allows network administrators a method of reserving bandwidth for important functions that require a large bandwidth or have a high priority, such as VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video conferencing.

  • Page 8: Understanding Qos

    Mapping QoS on the Switch The picture above shows the default priority setting for the Switch. Class-1 has higher priority than Class-0 on the Switch. In order to implement QoS, the user is required to instruct the Switch to examine the header of a packet to see if it has the proper identifying tag tagged.

    first. NPACKING AND ETUP Unpacking Open the shipping cartons of the DES-1024D and carefully unpack its contents. The carton should contain the following items: One DES-1024D 24-port 10/100Mbps Fast Ethernet Switch One AC power cord Four rubber feet to be used for shock cushioning Screws and two mounting brackets Quick Installation Guide Manual...

  • Page 10: Desktop Installation

    Desktop Installation When installing the DES-1024D on a desktop or shelf, the rubber feet included with the device should be attached first, to minimize scratching or scarring of the surface on which the Switch is placed. 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.
