1. Introduction Welcome to the World of Network Switching. In modern business, communication and information sharing are fundamental to success. Computer networks have proven to be one of the fastest ways of communication. The SmartGST-2402 is a multi-port Switch that can be used to build high- performance switched workgroup networks.

This revolutionized networking. First, by allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the bandwidth. Second, by reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing.
2. Hardware Description This Section describes the hardware of the SmartGST-2402 and gives a physical and functional overview of this switch. The physical dimensions: 440mm x 161mm x 44mm (L x W x H) Front Panel The Front Panel of the SmartGST-2402 consists of twenty-four 10/100Base- TX RJ-45 ports (Auto MDI/MDIX) and one expansion slot.
LED Indicators The LED Indicators give real-time information of systematic operation status. The following table provides a description of LED status. Figure 2-2. LED indicators LED Status Description Green Power On Power Off Power is not connected Green The port is connecting with the device.
as shown in Figure 2-3. The Switch will work with AC in the range 100-240V AC, 50-60Hz. Figure 2-3. The Rear Panel of SmartGST-2402 Desktop Installation Set the Switch on a sufficiently large flat space with a power outlet nearby. The surface where you put your Switch should be clean, smooth, level and sturdy.
Rack-mounted Installation The SmartGST-2402 comes with a rack-mounting kit and can be mounted in any EIA standard size, 19" Rack. The Switch can be placed in a wiring closet with other equipment. Perform the following steps to rack mount the switch: A.
Figure 2-5. Mounting the Switch in an EIA standard 19" Rack Note: For proper ventilation, allow about at least 4" (10 cm) of clearance on the front and 3.4" (8 cm) on the back of the Switch. This is especially important for enclosed rack installations.
3. Network Application This section provides a few samples of network topology in which the Switch is used. The SmartGST-2402 is designed as a segment switch. With its large address table (8 k MAC address) and high performance, it is ideal for interconnecting networking segments.
Figure 3-1. Small Workgroup Application Segment Bridge This switch is an ideal solution for departmental users in corporate backbones where large data broadcasts are constantly broadcast. In the illustration below, two Ethernet switches with PCs, a print server, and a local server are all connected to the Switch.
