ABOUT THIS GUIDE

Congratulations on your purchase of LevelOne

FSW-1610/2410TX 16/24-port 10/100Mbps Auto-negotiation

Fast Ethernet Switch. This device integrates 100Mbps Fast

Ethernet and 10Mbps Ethernet network capabilities in a highly

flexible package.

Purpose

This guide discusses how to install your 16/24-port 10/100Mbps Fast

Ethernet Switch.

Terms/Usage

In this guide, the term “Switch” (first letter upper case) refers to your

16/24-Port 10/100Mbps Fast Ethernet Switch, and ”switch” (first

letter lower case) refers to other Ethernet switches.

Overview of this User’s Guide

Introduction. Describes the Switch and its features.

Unpacking and Installation.Helps you get started with the basic

installation of the Switch.

Identifying External Components. Describes the front panel, rear

panel and LED indicators of the Switch.

Technical Specifications. Lists the technical (general, physical and

environmental, and performance) specifications of the Switch.

INTRODUCTION

This chapter describes the features of the Switch and some

background information about Ethernet/Fast Ethernet switching

technology.

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 were 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 rack size is specifically designed for middle to

large workgroups. The Switch provides 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 Switch 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 an unmanaged 10/100 Fast Ethernet Switch that offers

solutions in accelerating small Ethernet workgroup bandwidth. Other

key features are:

 16/24-Port 10/100BASE Ethernet Switch with RJ-45

connectors

 Support Auto-negotiation for speed and duplex modes

for each port

 Supports Auto-MDI/MDI-X for each port

 Wire speed reception and transmission

 Store-and-Forward switching method

 Integrated address Look-Up Engine, supports 8K

absolute MAC addresses

 Supports 1.25Mbits RAM for data buffering

 Front-panel diagnostic LEDs

 IEEE 802.3x flow control for full-duplex

 Back pressure flow control for half-duplex

 Standard 19” Rack-mountable size

UNPACKING AND INSTALLATION

This chapter provides unpacking and setup information for

FSW-1610/2410TX.

Unpacking

Open the shipping cartons of the Switch and carefully unpacks its

contents. The carton should contain the following items:

 One FSW-1610/2410TX

 One AC power cord, suitable for your area’s electrical

power connections

 Four rubber feet to be used for shock cushioning

 Screws and two mounting brackets

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

reseller for replacement.

Installation

The site where you install the Switch stack may greatly affect its

performance. When installing, consider the following pointers:

Install the Switch in a fairly cool and dry place. See Specifications

for the acceptable temperature and humidity operating ranges.

Install the Switch in a site free from strong electromagnetic field

generators (such as motors), vibration, dust, and direct exposure to

sunlight.

Leave at least 10cm of space at the front and rear of the hub for

ventilation.
