                          INTRODUCTION  This chapter describes the features of the Switch and some  background information about Ethernet/Fast Ethernet/Gigabit Ethernet  switching technology.  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 (

                          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  are essential to coping with the network bottlenecks that frequently  develop as compute

                          Switching Technology  Another approach to pushing beyond the limits of Ethernet technology  is the development 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 dividing a local  area

                          Installation  The site where you place the Switch may greatly affect its  performance. When installing, take the following into your  consideration:   Install the Switch in a site free from strong electromagnetic field  generators (such as motors), vibration, dust, and direct exposure  to sunlight.   Leave at least 10cm of space at the front and rear of the Switch for  ventilation.    Install the Switch on a sturdy, level surface that can support its  weight, or in an EIA standard-size equipme

                          Rack Mounting  The Switch can be mounted in an EIA standard-size, 19-inch rack,  which can be placed in a wiring closet with other equipments.  Attach  the mounting brackets to both sides of the Switch (one at each side),  and secure them with the provided screws.      Then, use screws provided with the equipment rack to mount the  Switch in the rack.      7

                          CONFIGURING THE SWITCH  This chapter explains how to configure the Switch to enable its smart  functions.     Port Speed & Duplex Mode  By default, the Switch determines the transmission mode by auto- negotiation for any new twisted-pair or fiber connection after  attaching the proper cable to a specific port.    For 10/100/1000Mbps RJ-45 ports, if the attached device does not  support auto-negotiation or has auto-negotiation disabled, an auto- sensing process is initiated to select speed (10M
