                        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 ov

                        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.

                        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  n

The primary utility of using VLAN is to reduce  latency and need for routers, using faster switching instead. Other  VLAN utility includes:  Security, Security is increased with the reduction of opportunity in  eavesdropping on a broadcast network because data will be switched  to only those confidential users withi

                        UNPACKING AND INSTALLATION  This chapter provides unpacking and installation information for the  Switch.  Unpacking  Open the shipping cartons of the Switch and carefully unpacks its  contents.  The carton should contain the following items:   One DGS-1224T Web Smart Switch   One AC power cord, suitable for your area’s electrical power  connections   Four rubber feet to be used for shock cushioning   Screws and two mounting brackets   CD-Rom with Web Management Utility and User’s Guide   Quick

                        Leave at least 10cm of space at the front and rear of the hub for  ventilation.  Install the Switch on a sturdy, level surface that can support its weight,  or in an EIA standard-size equipment rack.  For information on rack  installation, see the next section, Rack Mounting.  When installing the Switch on a level surface, attach the rubber feet to  the bottom of each device.  The rubber feet cushion the hub and  protect the hub case from scratching.    Figure 1. Attach the adhesive rubber pads
