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. It is a store-and-forward device

that offers low latency for high-speed networking and is targeted at

workgroup, department, or backbone computing environments.

Figure 1-1. SmartGST-2402

The SmartGST-2402's “store-and-forward“ switching scheme allows the

switch to auto-learn and store source address in an 8K-entry MAC address

table.

MDI (Medium Dependent Interface) Port is also called an "uplink port". The

MDI port does not cross the transmission and reception lines, which is done

by the regular ports (MDI-X ports) that connect to end stations. In general,

MDI means connecting to another Hub or Switch while MDIX means

connecting to a workstation or PC. Therefore, Auto MDI/MDIX means that

you can connect to another Switch or workstation without changing non-

crossover or crossover cabling.

The SmartGST-2402 has twenty four auto-sensing 10/100Base-TX RJ-45

ports plus one module slot for optional dual port 100Base-FX, 1000T, and

1000SX/LX Mini GBIC modules. This enables hi

erformance expansion

connections over long distances.

Ethernet Switching Technology

Ethernet Switching Technology dramatically boosted the total bandwidth of a

network, eliminated congestion problems inherent with CSMA/CD (Carrier

Sense multiple access with Collision Detection) protocol, and greatly reduced

unnecessary transmissions.

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. Third, by using the store-and-

forward technology’s approach of inspecting each packet to intercept corrupt

or redundant data. By employing address learning, this switching eliminated

unnecessary transmission that slowed the network.

Auto-negotiation regulates the speed and duplex of each port, based on the

capability of both devices. Flow-control allows transmission from a 100Mbps

node to a 10Mbps node without loss of data. Auto-negotiation and flow-control

may need to be disabled for some networking operations involving legacy

equipment. Disabling the auto-negotiation is accomplished by fixing the speed

or duplex of a port.

Ethernet Switching Technology supplies higher performance at lower costs

than other solutions. Wider bandwidth, no congestion, and the reduction in

traffic is why switching is replacing expensive routers and inefficient hubs as

the ultimate networking solution. Switching brings a whole new way of thinking

to networking.

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. The LED Indicators

are also located on the front panel of the Switch.

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. Make sure there is enough clearance around the Switch to allow

attachment of cables, power cord and allow air circulation.

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 bottom of the Switch. These

footpads can protect the Switch from shock/vibration.
