1. Introduction The 24 Port Micro-Switch/24 Desktop Fast Ethernet Switch is a multi-port Switch that can be used to build high-performance switched workgroup networks. This switch is a store-and-forward device that offers low latency for high-speed networking. It is targeted at workgroup, department, or backbone computing environments in SME (small, medium enterprise) businesses. The Micro-Switch/24 features a “store-and-forward “switching scheme. This allows the switch to auto-learn and store s

Ethernet Switching Technology Ethernet Switching Technology dramatically boosted the total bandwidth of a network, eliminated congestion problems inherent with Carrier Sense multiple access with Collision Detection (CSMA/CD) protocol, and greatly reduced unnecessary transmissions. This revolutionized networking in a number of ways. First, by allowing two- way, simultaneous transmissions over the same port (Full-duplex) which essentially doubled the bandwidth. Second, by reduci

Desktop Installation Set the Switch on a sufficiently large flat space with a power outlet nearby. The surface should be clean, smooth, level, and sturdy. Ensure there is enough clearance around the Switch to allow air circulation and the attachment of the power cord and cables. Attaching Rubber Feet A. Make sure mounting surface on the bottom of the Switch is grease and dust free. B. Remove adhesive backing from your Rubber Feet. C. Apply the Rubber Feet to each corner on the bott

3.Network Application This section provides a few samples of network topology in which the Switch is used. In general, the Micro-Switch/24 Desktop Fast Ethernet Switch is designed as a segment switch. That is, with its large address table (4K MAC address) and high performance, it is ideal for interconnecting networking segments. You can also use the Micro-Switch/24 to connect PCs, workstations, and servers to each other by connecting these devices directly to the Switch. The switch automatically

Segment Bridge For enterprise networks where large data broadcasts are constantly processed, this switch is an ideal solution for department users to connect to the corporate backbone. In the illustration below, two Ethernet switches with PCs, a print server, and a local server are both connected to the Micro-Switch/24. All devices in this network can then communicate with each other through the Micro-Switch/24. Connecting servers to the Switch allow other users to access the se

4.Troubleshooting This section is intended to help you solve the most common problems on the Micro-Switch/24 Incorrect connections Faulty or loose cables Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are snug. If this does not correct the problem, try a different cable. Non-standard cables Non-standard and miswired cables may cause numerous network collisions and other network problems that can seriously impair netw

Diagnosing LED Indicators The Switch can be easily monitored through panel indicators to assist in identifying common problems you may encounter and where you can find possible solutions. If the power indicator does not turn on when the power cord is plugged in, you may have a problem with power cord. Than check for loose power connections, power losses, or surges at power outlet. If you still cannot resolve the problem, contact your local dealer for assistance. Cabling RJ-
