INTRODUCTION

This chapter describes the features of the Switch and some background

Fast Ethernet Technology

The growing importance of LANs and the increasing complexity of desktop

computing applications are fueling the need for high performance networks.

A number of high-speed LAN technologies have been proposed to provide

greater bandwidth and improve client/server response times. Among them,

100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution

from the current 10BASE-T technology. The non-disruptive and smooth

evolution nature, and the dominating potential market base, virtually

guarantee cost effective and high performance Fast Ethernet solutions in the

years to come.

100Mbps Fast Ethernet is a new standard specified by the IEEE 802.3 LAN

committee. It is an extension of the 10Mbps Ethernet standard with the

ability to transmit and receive data at 100Mbps, while maintaining the

CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is

compatible with all other 10Mbps Ethernet environments, it provides a

straightforward upgrade and takes advantage of the existing investment in

hardware, software, and personnel training.

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology is the

development of switching technology. A switch bridge Ethernet packets at

the MAC address level of the Ethernet protocol transmitting among

connected Ethernet or Fast Ethernet LAN segments.

Switching is a cost-effective way of increasing the total network capacity

available to users on a local area network. A switch increases capacity and

decreases network loading by dividing a local area network into different

segments, which don’t compete with each other for network transmission

capacity.

The switch acts as a high-speed selective bridge between the individual

segments. The switch, without interfering with any other segments,

automatically forwards traffic that needs to go from one segment to another.

By doing this the total network capacity is multiplied, while still maintaining

the same network cabling and adapter cards.

For Fast Ethernet networks, a switch is an effective way of eliminating

problems of chaining hubs beyond the “two-repeater limit.” A switch can be

used to split parts of the network into different collision domains, making it

possible to expand your Fast Ethernet network beyond the 205-meter network

diameter limit for 100BASE-TX networks. Switches supporting both

traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for

bridging between the existing 10Mbps networks and the new 100Mbps

networks.

Switching LAN technology is a marked improvement over the previous

generation of network bridges, which were characterized by higher latencies.

Routers have also been used to segment local area networks, but the cost of a

router, the setup and maintenance required make routers relatively

impractical. Today switches are an ideal solution to most kinds of local area

network congestion problems.

Features

The Switch was designed for easy installation and high performance in an

environment where traffic on the network and the number of user increase

continuously.

The Switch with its small, compact size was specifically designed for small

to middle workgroups. This Switch can be installed where space is limited;

moreover, they provide immediate access to a rapidly growing network

through a wide range of user-reliable functions.

The Switch is ideal for deployment with multiple high-speed servers for

shared bandwidth 10Mbps or 100Mbps workgroups. With the highest

bandwidth 200Mbps (100Mbps full-duplex mode), any port can provide

workstations with a congestion-free data pipe for simultaneous access to the

server.

The Switch is expandable by cascading two or more switches together. As

all ports support 200Mbps, the Switch can be cascaded from any port and to

any number of switches.

The Switch is a perfect choice for site planning to upgrade to Fast Ethernet in

the future. Ethernet workgroups can connect to the Switch now, and change

adapters and hubs anytime later without needing to change the Switches or

reconfigure the network.

The Switch combine dynamic memory allocation with store-and-forward

switching to ensure that the buffer is effectively allocated for each port, while

controlling the data flow between the transmit and receive nodes to guarantee

against all possible packet loss.

The Switch is a 10/100 Fast Ethernet Switch that offers solutions in

accelerating small Ethernet workgroup bandwidth. Other key features are:

 Supports one 100BASE-FX multimode fiber port for long distance

connection, up to 2km in full-duplex mode.

 Supports seven 10/100Mbps NWay Ethernet RJ-45 MDI-X ports.

 Store and forward switching scheme capability. As the result of

complete frame checking and error frame filtering, this scheme

prevents error packages from transmitting among segments.

 NWay Auto-negotiation for RJ-45 ports (port-1 ~ port-7). This allows

for auto-sensing of speed (10/100Mbps) thereby providing you with

automatic and flexible solutions in your network connections.

Flow control for any port. The Switch provides back-pressure flow

control method for half duplex operation and IEEE 802.3x pause

frame-based flow control method for full duplex operation.

 Data forwarding rate per port is at wire-speed for 100Mbps and

10Mbps speed.

 Data filtering rate eliminates all error packets, runts, etc., per port at

wire-speed for 100Mbps and 10Mbps speed.

 1K MAC address entries table per device for the Switch.

 KB RAM buffer per device for the Switch.

UNPACKING AND SETUP

This chapter provides unpacking and setup information for the Switches.

Unpacking

Open the shipping cartons of the Switch and carefully unpacks its contents.

The carton should contain the following items:

One 8-Port 10/100Mbps NWay Ethernet Switch

One external power adapter

This User’s Guide

If any item is found missing or damaged, please contact your local reseller

for replacement.

Setup

The setup of the Switch can be performed using the following steps:

 The surface must support at least 1 Kg for the Switch.

 The power outlet should be within 1.77 meters of the Switch.

 Visually inspect the DC power jack and make sure that it is fully

secured to the power adapter.

 Make sure that there is proper heat dissipation from and adequate

ventilation around the Switch. Do not place heavy objects on the

Switch.

IDENTIFYING EXTERNAL COMPONENTS

This section identifies all the major external components of the hub. Both the

front and rear panels are shown followed by a description of each panel

feature. The indicator panel is described in detail in the next chapter.

Front Panel

The figure below shows the front panels of the switch.

LED Indicator Panel

Power Indicator (Power)

This LED indicator lights green when the switch is receiving power,

otherwise, it is off.

Full-Duplex/Collision (FDX/Col)

This LED indicator lights green when a respective port is in full duplex (FDX)

mode. Otherwise, it is blinking when collisions are occurring on the

respective port.

Link/Activity (100M LINK/ACT(green), 10M LINK/ACT(amber))

This LED indicator lights green when the port is connected to a 100Mbps

Fast Ethernet station, if the indicator blinking green will be transmission or

received data on the 100Mbps network. Otherwise, if the indicator lights

amber when the port is connected to a 10Mbps Ethernet station, if the

indicator blinking amber will be transmission or received data on the 10Mbps

network.

Rear Panel

DC Power Jack: Power is supplied through an external AC power adapter.

Since the switch does not include a power switch, plugging its power adapter

into a power outlet will immediately power it on.

Auto-MDI-X Function ports: Use these jacks (port-1 ~ port-7) to connect

stations to the hub. An Auto-MDI-X function will automatically detect if a

crossover is required and make the swap of Tx pair and Rx pair internally.

With this function, straight-through cable can be used for any connection.

MDI to MDI-X connection rule is not necessary anymore. In the switches, all

TP ports are equipped with this function. You can use just straight-through

type of cables for all your connections.

100BASE-FX Fiber Port: The Fiber port supports 100BASE-FX

62.5/1252m multimode fiber. The TX port has to link to others end RX port,

and the RX port has to link to others end TX port.

Duplex Mode Switch: The switch is to select the operation mode either to

run in full or half duplex mode for 100BASE-FX. When turning the switch to

FDX, the fiber port will run at full duplex or turn to HDX, the fiber will run

at half duplex.
