1. Introduction

The S8TB is a compact 8-port 10/100/1000Base-T Ethernet 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. The S8TB is targeted at workgroup, department or backbone computing environment at SME (small,

medium enterprise) business.

The S8TB features a “store-and-forward“ switching scheme which allows the switch to auto-learn and store

source address on the 8K-entry MAC address table.

Features

•Conforms to IEEE 802.3, 802.3u. 802.3ab, 802.3az, and 802.3x

•8 10/100/1000 Base-T RJ-45 Ethernet ports

•Auto-MDIX on all ports

•N-Way Auto-Negotiation supported

•Store-and-Forward switching architecture

•Non-blocking full wire speed

•Backplane Bandwidth 16 Gbps

•Embedded 128k bytes memory buffer

•8K MAC address table

•Up to 9K byte Jumbo Frame

Package Contents

Unpack the contents of the S8TB packaging and verify them to the checklist below.

•One S8TB Switch

•One Documentation Post card

•Four Rubber Feet

•Four Sponges

•One Wall Mount Kit (two brackets)

Compare the contents of your S8TB package with the standard checklist above. If any item is missing or

damaged, please contact your local dealer for service. Save the packaging materials for possible future use.

Ethernet Switching Technology

Ethernet Switching Technology dramatically boosted the total bandwidth of a network, eliminated congestion

problems inherent in Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol, and greatly

reduced unnecessary transmissions.

With this revolutionized networking, the system is capable of: First, allows two-way, simultaneous transmissions

over the same port (Full-duplex) to essentially double the bandwidth. Second, reduces the collision domain to a

single switch-port to eliminate the need for carrier sensing. Third, uses the store-and-forward technology’s

approach of inspecting each packet to intercept corrupt or redundant data, and eliminates unnecessary

transmission that slows the network. In addition, the system employs address learning to replace the inefficient

method of constant broadcasting to every node in search of the correct receiving port.

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 require disablement for some networking operations involves legacy equipment. Disabling

the auto-negotiation is accomplished by fixing the speed or duplex of a port.

Ethernet Switching Technology supplied higher performance at costs lower than other solutions. Wider bandwidth,

no congestion, and the reduction in traffic are reasons why the Ethernet Switch is replacing expensive routers and

inefficient hubs as the ultimate networking solution. Switching brought a whole new way of thinking to networking.

2. Hardware Description

This section mainly describes the hardware of the 8-port 10/100/1000Base-T Switch, and gives a physical and

functional overview of the Switch.

Physical Dimensions

The physical dimension of the 8-port 10/100/1000Base-T Switch is 165mm x 32.5mm x 100 mm (W x H x D).

LED Indicators

The LED Indicators gives real-time information of systematic operation status. The following table provides

descriptions of LEDs status and their meaning.

LED Panel

LED Indicator Descriptions

LED Status Description

Steady Green Port connection on 1000Mbps

LK/ACT Steady Amber Port connection on 10/100Mbps

Off Port disconnect

Power On

Connect the power cord to the power socket on the rear panel of the Switch.

Connect the other side of power cord to the power outlet.

The power rating of the switch is AC voltage ranging from 100-240VAC, frequency 50~60Hz.

3. Troubleshooting

This section is intended to help you solve the most common problems on the S8TB switch.

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 that does not correct the problem, try a different cable.

•Non-standard cables

Non-standard and mis-wired cables may cause numerous network collisions and other network problem, and can

seriously impair network performance. A category 5-cable tester is a recommended tool for every 100Base-TX

network installation.

RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: 100Ω

Category 3, 4 or 5 cable for 10Mbps connections or 100Ω Category 5 cable for 100Mbps connections.

Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

•Improper Network Topologies

It is important to make sure that you have a valid network topology. Common topology faults include excessive

cable length and too many repeaters (hubs) between end nodes. In addition, you should make sure that your

network topology contains no data path loops. Between any two end nodes, there should be only one active

cabling path at any time. Data path loops will cause broadcast storms that will severely impact your network

performance.

Diagnosing LED Indicators

The switch can be easily monitored through panel indicators, which describe common problems you may

encounter, to assist in identifying problems and where you can find possible solutions.

See the section “LED Indicators” on page 6above.
