INTRODUCTION This chapter describes the features of the 24-Port 10/100Mbps Fast Ethernet Smart Switch and some background information about Ethernet/Fast 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. A

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

VLAN (Virtual Local Area Network) A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if in a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency and need for routers, using faster switching instead. Other VLAN utility include: 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

Installation The site where you install the hub stack may greatly affect its performance. When installing, consider the following pointers: Install the Switch in a fairly cool and dry place. See Technical Specifications for the acceptable temperature and humidity operating ranges. 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
