INTRODUCTION

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. An important strategy incorporated by 100BaseT is its use of the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol – which is the same protocol that 10BaseT uses – because of its ability to work with several different types of cable, including basic twisted-pair wiring.

Both of these features play an important role in network considerations, and they make 100BaseT an attractive migration path for those networks based on 10BaseT. 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

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. A switch is a viable solution even if demanding applications, such as multimedia production and video conferencing, are on the horizon.

The most promising techniques, as well as the best return on investment, could well consist of installing the right mixture of Ethernet switches. A switch increases capacity and decreases network loading by dividing a local area network into different LAN segments. Dividing a LAN into multiple segments is one of the most common ways of increasing available bandwidth. If segmented correctly, most network traffic will remain within a single segment, enjoying the full-line speed bandwidth of that segment.

Switches provide full-line speed, dedicated to bandwidth for all connections. This is in contrast to the hubs, which use the traditional shared networking topology, where the connected nodes contend for the same network bandwidth. When two switching nodes are communicating, they are connected with a dedicated channel between them, so there is no contention for network bandwidth with other nodes. As a result, the switch reduces considerably the likelihood of traffic congestion.

For Fast Ethernet networks, a switch is an effective way of eliminating the problem of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of the network into different collision domains, 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 the existing 10Mbps networks and the new 100Mbps networks.

Switching LAN technology is a marked improvement over the previous generation of network hubs and bridges, which were characterized by higher 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.

UNPACKING AND SETUP

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

If any item is found missing or damaged, please contact your local reseller for replacement.

Setup

The setup of the DES-1024D can be performed by using the following steps:

1. The surface must support at least 11 lbs (5 kg).
2. The power outlet should be within 6 feet (1.42 meters) of the device.
3. Visually inspect the power cord and see that it is secured fully to the AC power outlet.
4. Make sure that there is adequate ventilation around the Switch.
5. Do not place heavy objects on the Switch.

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.

Rack Mounting

The DES-1024D can be mounted in an EIA standard-size 19-inch rack, in a wiring closet with other equipment. Attach the mounting brackets on each side of the Switch’s front panel (as shown in the illustration below), and secure them with the screws provided.

LED Indicator Panel
Refer to the next chapter for detailed information about each of the switch’s LED indicators.

• Power (PWR)
  This green LED indicator illuminates when the switch is receiving power; otherwise, it is off.

• Link / Activity
  This green LED indicator illuminates when the port is connected to a Fast Ethernet or Ethernet station; the indicator blinks when transmitting or receiving data.

• 100Mbps (green)
  This green LED indicator illuminates when the port is connected to a 100Mbps Fast Ethernet station. The LED does not illuminate when the port is connected to 10Mbps Ethernet station.

Twisted-Pair Ports
These ports support automatic MDI/MDIX crossover detection function providing true ‘plug and play’ connectivity, which eliminates the need for crossover cables or uplink ports. Any port can be simply plugged to a server, workstation, or hub using the usual straight-through, twisted-pair cable.
