A BOUT T HIS G UIDE Congratulations on your purchase of the 24-port 10/100Mbps Auto-negotiation Fast Ethernet Switch. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Purpose This guide discusses how to install your 24-port 10/100Mbps Fast Ethernet Switch.
I NTRODUCTION This chapter describes the features of the 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.
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.
Features The Switch is designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. The Switch with its rack size is specifically designed for middle to large workgroups. The Switch provides immediate access to a rapidly growing network through a wide range of user-reliable functions. The Switch is ideal for deployment with multiple high-speed servers for shared bandwidth 10Mbps or 100Mbps workgroups.

U NPACKING AND I NSTALLATION This chapter provides unpacking and setup information for the Switch. Unpacking Open the shipping carton of the Switch and carefully unpack its contents.
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 equipment. Attach the mounting brackets at the switch’s front panel (one on each side), and secure them with the provided screws. Then, use screws provided with the equipment rack to mount each switch in the rack.
I DENTIFYING E XTERNAL C OMPONENTS This section identifies all the major external components of the switch. Front Panel The figure below shows the front panels of the switch.
Twisted-Pair Ports These ports support the automatic MDI/MDIX crossover detection function which provides true ‘plug and play’ capability without the need of confusing crossover cables or crossover ports. With the Auto-MDI function, you simply plug-in the network cable to the unit directly with no need to care if the end node is a NIC (Network Interface Card) or switches and hubs.
