                        INTRODUCTION  This chapter will describe the features of the DES-1228P and provide  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, and management objects, but with a tenfold increase in  theoretical throughput of over 100-Mbps Fast Ethernet and a  hundredfold increase

                        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 connec

                        Switching Technology  Another approach to push 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  netwo

                        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 (about 4 inches) of space to 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 equipment rack.  For information  on rack installation, see the next section, Rack Mounting.

                          AC Power   The Switch utilizes an AC power supply 100~240V AC, 50~60Hz.  The power switch is located at the rear of the unit adjacent to the AC  power connector and the system fan.   The switch’s power supply will adjust to the local power source  automatically and may be turned on without having any or all LAN  segment cables connected.  1 14 4
