1 Product Overview

Introduction

5× 10/100/1000Base-T port Gigabit Ethernet Switch with Broadcast Storm Control

Live-GSH5T Gigabit Ethernet Switch is an auto-sensing and auto-negotiating Gigabit Ethernet Switch with Broadcast Storm Control capability. Its five 10/100/1000Mbps Gigabit ports provide 10/100/1000Mbps connections to PC with gigabit cards or gigabit switches

Live-GSH5T's unique switching fabric provides non-blocking full wire speed for all ports. Auto MDI/MDIX function is provided for conventional uplinking to another switch/hub using ordinary straight-through cable. Each port provides up to 2000Mbps in full duplex mode. With its auto-sensing, Live-GSH5T automatically detects the speed of the devices you plug into, and routes the incoming data to its destination. Its auto-negotiating function allows existing devices running at different speeds to communicate easily within the same network.

Broadcast Storm Control

The Live-GSH5T automatically filters out the broadcast traffic when the broadcast packets exceed 5% of the total traffic. Broadcast storm can significantly impede the performance of the network. The Live-GSH5T protects your network from such situations.

Store-and-Forward Architecture against Packet Loss

When network is under heavy traffic, the shared memory buffer in the switching devices might yield incorrect detections due to overfed memory buffer. This setback can happen either when data is transmitted in IEEE802.3x Full Duplex or Back Pressure Flow Control mode. To solve this problem, Live-GSH5T utilizes a fixed memory buffer allocation with Store-and-forward transmission to ensure an effective buffer allocation for each port.

Store-and-forward transmission controls data flow from transmitting to receiving nodes with the receiving buffer threshold adjusted to an optimal value, thus guaranteeing against all possible packet losses.

Active Flow Control

Live-GSH5T Gigabit Ethernet Switch implements in full duplex mode a flow control that is compliant to IEEE 802.3x standard. While in half duplex mode, it employs an optional Back

Pressure Flow Control to stall the incoming data when port buffers are saturated. With this flow control mechanism, it can be ensured that frames dropped during transmission are reduced to a minimum.

Non-blocking Wire Speed

Live-GSH5T's non-blocking cross-bar matrix architecture provides high-end performance for departmental and workgroup environments at a fraction of the cost of similar devices. Typically, this type of architecture was found only in high-end switches designed to handle huge corporate networks. With bandwidth needs and network efficiency concerns, Live-GSH5T's switching fabric design is the perfect answer for solution.

System/Port Status Information at a Glance

There are 2 sets of LEDs on the front panel: System LED and Station port LEDs.,. The System LEDs consist of the Power LED, the BCST(Broadcast Storm Control)/Diag and OvUn_Flow LED. The station LEDs consist of the 10M Link/Act, 100M Link/Act, 1000M Link/Act

What's Broadcast Storm Control

Broadcast Storm is the result of too much broadcast traffic in the network. Broadcast packets are sent to every stations in the network, thus increase the overall network traffic. Broadcast storm are likely to decrease the network performance significantly. Broadcast Storm occurs usually when there is a loop formed in the network or when a particular application creates unordinary amount of broadcast packets. The Live-GSH5T has built-in broadcast storm control which filter out the broadcast traffic when it exceeds 5% of total traffic.

Solution for the digital media age

In the age of digital media, the computer has become the storage center for DV, DVD video, and digital pictures. Furthermore, the majority of the worldwide TV format will turn to HDTV and other digital standard in the next few years. The demand for faster network will increase dramatically. Gigabit Ethernet will make playing DVD quality video over the network a reality. In addition, copy Gigabytes of data over network will no longer be a time consuming process. With the Live Series Gigabit Ethernet switch, building a network capable of fast large file sharing and real time play back of high quality audio/video is simple and affordable.

Why Copper-wired Gigabit Connection?

With the tremendous success of Ethernet in LAN, twisted-pair cable has become the most ubiquitous networking media all over the world. It also costs less than the fiber-optic cable. Thus, it is very convenient to choose a copper-wired gigabit switch such as Live-GSH5T, since you can easily set up a gigabit backbone using the kind of twisted-pair cable so ordinarily used in 10/100BASE-TX environment.

Cabling Requirements

Live-GSH5T Gigabit Ethernet Switch is primarily designed as a central switching device to provide Gigabit bandwidth to your existing Ethernet/Fast Ethernet LAN. It provides you with five built-in gigabit ports to establish gigabit backbone connections, relieving your network bottleneck. It fits well into the 10/100/1000 BASE-T cabling architecture to facilitate not only 10/100Mbps half/full duplex, but also 1000Mbps full-duplex transmission speed.

The five RJ-45 station ports (Auto MDI/MDI-X) all require Cat. 5 twisted-pair UTP/STP cable for connection. When configuring within the 10/100/1000BASE-TX cabling architecture, the UTP cabling distance should be within a maximum distance of 100m .

The table below describes when to use straight-through or crossover cable:

Connection Specification	Station Port 10/100/1000BASE-T
Interface	RJ-45

Table 3-1 Using straight-through and crossover cables

Cable to Use
To an end station	Straight-through twisted-pair cable
To a hub/switch	Straight-through twisted-pair cable
Maximum Distance	100 meters

RJ-45 station port cable requirements:

10BASE-T	100 ohm Category 3, 4, 5 UTP/STP cable
100BASE-TX	100 ohm Category 5 UTP/STP cable
1000BASE-T	100 ohm Category 5 UTP/STP cable or better

Straight-through cabling requirements

Under most conditions, the 5 station ports on the Switch accept normal, straight-through cables, i.e., standard UTP/STP cables, which are the only ones that can be used with a RJ-45 pin layout.

Normally, 10BASE-T networks require a straight-through Cat. 3, 4, 5 UTP/STP cabling system. The cabling system could be found in most existing Ethernet network installations. 100/1000BASE-T networks require Cat. 5 UTP/STP cabling system. The pin assignments for a straight-through cable are shown in Figure 3-5 and 3-6.

Port cabling requirements

The 10/100/1000BASE-T port can automatically determine whether or not it needs to cross over between pairs as shown in Table 3-2 below. Therefore, the ports do not require crossover cables when connecting to another Switch.

If Live-GSH5T interoperates with a device that cannot automatically correct for crossover, it makes the necessary adjustment prior to commencing auto-negotiation. If it interoperates with a device that implements MDI/MDIX crossover, a random algorithm as described in IEEE 802.3 section 40.4.4 determines which device performs the crossover.

4 Expanding Your Network

Live-GSH5T Gigabit Ethernet Switch is primarily designed as a central switching device to manage your workgroup/departmental traffic within Ethernet/Fast Ethernet/Gigabit Ethernet.

The following section will introduce to you the basics of network connectivity in virtual workgroup computing within Ethernet/Fast Ethernet/Gigabit Ethernet environment.

Connectivity Rules

10 Mbps Connection (10BASE-T)

Ethernet connection should be configured according to the following connectivity rules:

• The maximum length for UTP cables must not exceed 100 meters from end station to a shared-access 10BASE-T hub.
• Between any two end stations in a collision domain, there may be up to five cable segments and four intermediate repeaters at most.
• If there is a path between any two end-stations containing five segments and four repeaters, then at least two of the cable segments must be point-to-point link segments (e.g. 10BASE-T or 10BASE-5), while the remaining segments may be of mixed segments (e.g.: 10BASE-2 or 10BASE-5).

Copper-wired 100/1000 Mbps Connection (100/1000BASE-T)

Copper-wired Fast Ethernet/Gigabit Ethernet connection should be configured according to the following connectivity rules:

• The maximum length for STP/UTP cable is 100 meters from end station and a shared-access 100BASE-TX hub.
• The maximum cable length is 100 meters between end station and switch/repeater; and 100 meters between switch and switch/repeater, thus making possible a maximum distance of 300 meters between two end stations.

Connecting to another Switch/Hub

Straight-through Cable Connection

Because the switch is equipped with auto-MDI/MDIX function for every port, users can use straight-thru cable for any type of connection. There is no need for crossover cables.

Fig. 4-1 Connecting two switches

RJ-45 Gigabit Port Description

The RJ-45 Gigabit port can automatically determine whether it needs to cross over between pairs as shown in Table 4-1. Therefore, the 1000BASE-T gigabit port does not require an external crossover cable when connecting to another Gigabit switch.

Table 4-1 1000BASE-T pin assignments for RJ-45 connector

Pin Assignment	MDI	MDIX
MDI[0]+/-	BI_DA+/-	BI_DB+/-
MDI[1]+/-	BI_DB+/-	BI_DA+/-
MDI[2]+/-	BI_DC+/-	BI_DD+/-
MDI[3]+/-	BI_DD+/-	BI_DC+/-

Summary:

• When connecting a computer to the station port/gigabit port of the Live-GSH5T, use a straight-through UTP cable.
• When connecting the gigabit port of Live-GSH5T to the station port of another hub/switch, use a straight-through cable.
• When uplinking Live-GSH5T to any port (MDI-X) of another hub/switch, use a straight-through cable. Please note that the cabling distance is 100 meters maximum.
• When using crossover cable, the connection can be made from any station ports (MDI-X) of Live-GSH5T to any station ports (MDI-X) of other devices.

Copper-wired Gigabit Connection

Each Gigabit port should utilize a twisted-pair straight-through cable with a RJ-45 connector to connect to another Gigabit RJ-45 port on other Gigabit networking device. Gigabit Ethernet use all 4 pairs of the UTP cable. We recommend Cat.5E or better UTP/STP cable for Gigabit connection.

Gigabit Backbone Connections

Live-GSH5T Gigabit Ethernet Switch serves primarily as a backbone switch to connect your existing Ethernet/Fast Ethernet network to Gigabit networking environment. Live-GSH5T can provide five 1000BASE-T gigabit backbone connections to another gigabit switch or high-end server. With gigabit throughput, backbone traffic can be greatly improved for the ever-increasing bandwidth demand by the internet/intranet multimedia applications.

5 LED Indicators

Before connecting any network device to Live-GSH5T Gigabit Ethernet Switch, you should take a few minutes to look over this chapter and get familiar with the front panel LED indicators of your Switch. The front-panel LED indicators of Live-GSH5T Gigabit Ethernet Switch comprise three sets of LEDs: System Status LEDs, Diagnostic LEDs, and Gigabit Port LEDs. Each set of LEDs gives specific information concerning the system status, station port status or the Gigabit port status:

Comprehensive LEDs

System LED

Power LED enables users to monitor the system power Status.

Diagnostic LEDs

The Diagnostic LEDs consist of the Bcst/DIAG and OvUn Flow LEDs. Together, they display the operating status of the switch and the traffic monitor

Station Port LEDs

Gigabit Port LEDs show the port status of the Gigabit Ports on the optional modules installed. Link/Act, 10/100 and 1000/FDX LEDs indicate the connection status of the Gigabit port.

For the layout of LED indicators, please refer to Fig. 5-1 below.

Fig. 5-1 Front-panel LED indicators

The specific function of each LED will be described in full details in the following sections:

Power LED

Power LED will give a solid green light when you turn on the Switch, and will be off when the Switch being turned off. You can simply check the Power LED to see if the Switch is being activated. Before turning on the Switch, please verify that the power cord has been properly connected to the Switch and the power outlet on the wall.

Diagnostic LEDs

The Diagnostic LEDs help you to troubleshoot the network problem.

BCST/DIAG LED

The BCST/DIAG has two functions:

Power-On Diagnostic Test:

When the switch is powered on, the system will perform a power-on diagnostic test. Under normal condition, the BCST/DIAG will flash once and remain off. If the LED remained lit after several seconds, then the switch might fail the power-on test.

□ Broadcast Storm Control

When broadcast traffic exceeds 5% of total traffic. The BCST/DIAG LED will keep on flashing to indicate that the switch is filtering out the broadcast packets. The light will be off when the broadcast traffic is below 5% again.

Gigabit Port LEDs (for Port #1 ~ 5)

10M/100M/1000M Link/Act LED

Link/Act LED giving a solid green light indicates that a full duplex data link has been established between the corresponding port and the device. If the connection is faulty, it will be off. While the port is transmitting or receiving data, you will see a blinking light.

Green 10M Link/ACT: A 10Mbps connection has been made

Green 100M Link/ACT: A 100Mbps connection has been made
