1 INTRODUCTION

This section describes the features of the DES-1008FX, as well as
giving some background information about Fast Ethernet
switching technology.

Fast Ethernet Technology

The growing importance of LAN s and the increasing complexity
of desktop computing applications are fueling the need for high
performance networks. A number of high-speed LAN technologies
are proposed to provide greater bandwidth and improve
client/server response times. Among them, Fast Ethernet, or
100Base-TX or 100Base-FX, provides a non-disruptive, smooth
evolution from the current 10Base-T technology. The non­disruptive 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

Introduction 1

takes advantage of the company’s 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
bridges 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 making it
possible for a local area network to be divided into different
segments which don’t compete with each other for network
transmission capacity, giving a decreased load on each.

The switch acts as a high-speed selective bridge between the
individual segments. Traffic that needs to go from one segment to
another is automatically forwarded by the switch, without
interfering with any other segments. This allows the total
network capacity to be 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-FX networks. Switches supporting both traditional
10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for
bridging between existing 10Mbps networks and new 100Mbps
networks.

2 Introduction

User’s Guide

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 and the setup and
maintenance required make routers relatively impractical.
Today’s switches are an ideal solution to most kinds of local area
network congestion problems.

Features

The DES-1008FX Switch was designed for easy installation and
high performance in an environment where traffic on the network
and the number of users increase continuously.

The DES-1008FX Switch features:

Ports

♦ 8 high performance 100BaseFX ports all operating at 100

Mbps for connection to workstation, servers and hubs. All
ports can be selected to perform half-duplex or full duplex
connections.

♦ Select any of 8 ports for uplink/ MDI-X (media dependent

interface) port for uplink to another switch, hub or repeater.

Performance features

♦ Store and forward switching scheme capability to support

rate adaptation and protocol conversion.

Introduction 3

♦ Full and Half-duplex at 100Mbps to allow two

communicating stations to transmit and receive at the same
time.

♦ Data forwarding rate 148,800 pps per port at 100% of fiber-

speed.

♦ Data filtering rate eliminates all error packets, runts, etc. at

148,800 pps per port at 100% of fiber-speed.

♦ 8K active MAC address entry table per device with self-

learning and table aging.

♦ 2 MB packet buffer per port.
♦ Supports broadcast storm rate filtering.

4 CONNECTING THE

SWITCH

This chapter describes how to connect the DES-1008FX to your
Fast Ethernet network.

PC to Switch

A PC can be connected to the Switch via a two-string fiber straight
cable. The PC (equipped with a 100 Mbps SC jack) should be
connected to any of the eight ports (1x - 8x) of the DES-1008FX.

The LED indicators for PC connection are dependent on the LAN
card capabilities. If LED indicators are not illuminated after
making a proper connection, check the PC’s LAN card, the cable,
Switch conditions and connections.

NOTE: If your SC connectors are not locked together the TX and
RX on the PC's side, the cable connectors at the switch must
reversed to RX and TX of the Switch. This allows a TX from the
card to enter into the RX of the switch. Locked (paired) SC
connectors should be manufactured in this manner.

The following are LED indicator possibilities for a PC to Switch
connection:

14 Connecting The Switch

User’s Guide

1. The Link LED indicator comes ON upon hookup.

2. The Act. LED indicator illuminates if dataupon hookup.

3. The FDX LED indicator depends upon LAN card capabilities

and DIP switch setting at DES-1008FX back panel.

4. The Col. LED indicator depends upon communication
activity.

Hub to Switch

A hub (100Base-FX) can be connected to the Switch via a two­string fiber crossover cable.

NOTE: If your SC connectors are not locked together the TX and
RX on the PC's side, the cable connectors at the switch must
reversed to RX and TX of the Switch. This allows a TX from the
card to enter into the RX of the switch. Locked (paired) SC
connectors should be manufactured in this manner.

100Base-FX Hub

A traditional repeater/hub can only accomplish Half-Duplex
setting. Set the DES-1008FX Duplex Mode switches for Half­Duplex of the ports that are hook to these hubs.

For a 100Base-FX hub, the Switch’s LED indicators should
illuminate the following:

♦ The Link LED indicator comes ON upon hookup.
♦ The Act. LED indicator illuminates if data upon hookup.
♦ The FDX LED indicator should be off.

Connecting The Switch 15

♦ The Col. LED indicator depends upon communication

activity.

Switch to Switch

A 100Base-FX compatible switch can be connected to the Switch
via a two-string fiber crossover cable.

Switch the Duplex mode switches to the appropriate selections to
get the maximum bandwidth. Consult the other switches manual
for the proper setting of Duplex Modes. The DES-1008FX Duplex
Mode switches can be found on the back of the unit. "DOWN/ON"
is Half-Duplex and "UP/OFF" is Full-Duplex.

NOTE: If your SC connectors are not locked together the TX and
RX on the PC's side, the cable connectors at the switch must
reversed to RX and TX of the Switch. This allows a TX from the
card to enter into the RX of the switch. Locked (paired) SC
connectors should be manufactured in this manner.

The "uplinked" Switch LED indicators for the respective connected
ports are as follows:

♦ The Link LED indicator comes ON upon hookup.
♦ The Act. LED indicator illuminates if data upon hookup.
♦ The FDX LED indicator depends upon the "uplinked"

switch's capabilities and Duplex Mode switch setting at
DES-1008FX back panel.

♦ The Col. LED indicator depends upon communication

activity.
