ABOUT THIS GUIDE Congratulations on you r purchase of the Web Smart 48+2G-Port 10 /100/1000Mbps/SFP Switch. This d evice integrates 1000Mbp s Gigabit Ethernet, 100Mbps Fast Ethernet, an d 10Mbps Ethernet network capab ilities in a highly flexib le package.
INTRODUCTION This chapter describes the features of the Web-Smart 48+2G-P o rt 10/100/1000Mbps/ SFP Switch and some background information about Ethernet/Fast Ethernet/Gigab it Eth ernet switching technology. Gigabit Ethernet Technology Gigabit Ethernet is an extension of IEEE 802.
VLAN (Virtual Local Area Network) A VLAN is a gro up of end-stati ons that are not const rained by their physical location an d can communi cate as if a common broad c ast domain, a LAN. The primary utility of using VLAN is to reduce late ncy and the need for routers, by us ing faster switching inste ad.
Features 48×10/100M bps Auto-neg otiation Fast Ethernet RJ -45 ports 2×10/100/10 00Mb ps Au to-negotiatio n Gigabit RJ-45 por ts 2×mini-GB IC/SFP ports, share with the 2 gigabit c opper.
UNPACKING AND INSTALLATIO N This chapte r provides unpacking an d installat ion inform ation for the Switch. Unpacking Open the shi pping carto ns of the Swi tch and caref ully unpacks i ts contents .
AC Power The Switch uses a 100-240V AC, 50-60 Hz AC power supply . The powe r switch is located at the rear of the unit adjacent to the AC power connector and the system fan. The Switch’ s pow er supply will adjust to the local power source automaticall y and may be turned on without having a ny or all LAN segment cables connected.
