24-Port 10/100Mbps Ethernet Switch User Guide About This Guide Congratulations on your purchase of the 24-port 10/ 100Mbps 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 Ethernet Switch.
24-Port 10/100Mbps Ethernet Switch User Guide Introduction 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 local area networks (LANs) and the increasing complexity of desktop computing applications are fueling the need for high performance networks.
24-Port 10/100Mbps Ethernet Switch User Guide Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridge 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.
24-Port 10/100Mbps Ethernet Switch User Guide characterized by higher latencies. Routers are also used to segment LANs. However, since routers are expensive, difficult to setup, and require intensive maintenance, they are relatively impractical for the network. Switches, on the other hand, are less expensive, easier to set up, and practically maintenance free, which make them an ideal solution to today's LAN congestion problems.
24-Port 10/100Mbps Ethernet Switch User Guide anytime later without needing to change the Switch or reconfigure the network. The Switch combine dynamic memory allocation with storeand-forward switching to ensure that the buffer is effectively allocated for each port, while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss.
24-Port 10/100Mbps Ethernet Switch User Guide Unpacking Open the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items: • • • • • One the 24-port 10/100Mbps Fast Ethernet Switch One AC power cord, suitable for your area's electrical power connections Four rubber feet for shock cushioning Screws and two mounting brackets This User Guide If any item is missing or damaged, contact your local reseller for replacement.
24-Port 10/100Mbps Ethernet Switch User Guide 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. 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 (see Figure 1). Figure 1.
24-Port 10/100Mbps Ethernet Switch User Guide Then, use screws provided with the equipment rack to mount each switch in the rack (see Figure 2). Figure 2. Attach Switch to Rack External Components This section identifies all the major external components of the switch. Front Panel Figure 3 shows the front panels of the switch.
