1 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.
2 Package Contents Unpack the contents of the Micro-Switch/24 Desktop Fast Ethernet Switch and verify them against the checklist below. Micro-Switch/24 Desktop Fast Ethernet Switch User Guide Power Cord Four Rubber Feet Micro-Switch/24 User Guide Power Cord Rubber Feet Figure 1-2.
3 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.
4 2. Hardware Description This Section describes the hardware of the Micro-Switch/24 Desktop Fast Ethernet Switch/. The physical dimensions of the Micro-Switch/24 are: 250mmx 133 mm x 37mm (L x W x H) Front Panel The Front Panel of the Micro-Switch/24 consists of twenty-four (24) 10/100Base-TX RJ-45 ports.

6 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.
7 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.
8 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.
9 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.
10 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.
