2 Hardware Description

Product Overview

The Converter is enhanced with Link Fault Signaling
(LFS) and Loopback Test (LBK) functions to offer the
most comprehensive network status monitoring and
connection diagnostics. It is designed for large
workgroups who demand higher speed and wider
bandwidth. It allows migration and expansion from a
copper-based Ethernet to a fiber optic Fast Ethernet.

It features automatic MDI detection setting. This
function allows for simple direct connection to a
workstation, switch or hub. Therefore, network
managers no longer need to worry about cable type
configuration when establishing a connection between
RJ-45 ports.

This Converter is equipped with an RJ-45 port and a
fiber optic ST or SC or WDM port. This allows it to
quickly integrate a 10/100Base-TX network into a
100Base-FX (fiber) network.
It features DIP switches for manual half or full duplex
mode configuration on both copper and fiber ports. In
full duplex mode, this Converter has the ability to
support distances of up to 2 kilometers for multi-mode

EX-9543 Enhanced 10/100Base-TX to 100Base-FX Converter

- 9 -

NWay DIP Switch Setting

Use the NWay DIP switch to activate NWay

operations.

Factory NWay DIP switch default set to ON position.

Check that the networking device to be connected to

the Converter has NWay support.

If YES: Check that the NWay DIP switch is set to the

ON position. The Converter will automatically

set the optimum speed and duplex mode on

the copper segment. Users can skip the

settings for DIP switches 2 and 3, when NWay

is activated.

If NO: Set the NWay DIP switch to the OFF position.

Then Use DIP switch 2 to manually select

between half (HD) and full duplex (FD) modes.

Use DIP swit ch 3 to manually select between

10Mbps or 100Mbps speeds. Set NWay

switch to OFF position when connecting to an

auto-sensing device that only supports

10/100Mbps detection. Some early switch

EX-9543 Enhanced 10/100Base-TX to 100Base-FX Converter

- 10 -

models only support auto-sensing of speed,

and NOT auto detection of speed and duplex

mode (auto-negotiation).

NWay DIP Switch Setting continue

Setting the duplex mode is feasible while the
media converter is “on-line”

Note: If you experience the following problems, please

check if the NWay switch is properly set.

1. The LNK (link) LED is not lit and the

connection cannot be established

2. The LNK LED is lit and the connection is ok,

but cannot transmit or receive data

3. The converter functions properly for a while,
then, it does not work. And then it works after
powering off and then on again.

Important

In order to configure DIP switches 2 (duplex
mode) and 3 (speed), you must set DIP
switch 1 (NWay) to the OFF position

EX-9543 Enhanced 10/100Base-TX to 100Base-FX Converter

- 11 -

Link Fault Signaling (LFS)

LFS is a “nice to have” function that is extremely

beneficial in terms of network status monitoring. The

LFS LED will immediately light to indicate when a

cable has been severed or when some other cause of

disruption in service has occurred. The LFS function

monitors both copper and fiber segments giving a total

connection status report.

Set LFS to ON position for normal operational use.
Set LFS to OFF position when installing cables or

when testing the network connection.

Note: The LFS feature influences both fiber and

copper segments. Therefore, when disruption occurs

on either segment, the LFS feature will be activated

and the LED will light to indicate that the entire

connection is down.

To appreciate the full benefits of LFS, four converters

can be used to build a primary and a secondary link.

They must be connected to a switch that supports

Spanning Tree or Fast Spanning Tree protocols. By

default, transmission of data will travel via the primary

link. Once a fault has been detected, transmission will

EX-9543 Enhanced 10/100Base-TX to 100Base-FX Converter

- 12 -

automatically be switched to the secondary link,

resulting in ‘non-stop’ network connectivity.

Loopback Test

This Converter features DIP switches to activate both

local and remote loopback diagnostic test functions.

Use local loop back to check if the copper segment is

connected properly, and use remote loop back to

check if the fiber segment is connected properly.

Please see Diagram below:

Dip Switch 6 ON: enables local loop back function

OFF: disables local loop back function

Dip Switch 7 ON: enables remote loop back function

OFF: disables remote loop back function

Make sure that the cables are connected properly

before getting started. Conduct either the local or

remote test, not both at the same time. Follow the

steps below to perform the diagnostic tests.

Getting Connected

Powering On Unit

The Converter uses an AC power supply 100~240V

AC, 50~60 Hz. The Converter's power supply

automatically self-adjusts to the local power source

and may be powered on without having any or all LAN

segment cables connected.

1. Insert the power cable plug directly into the

receptacle located at the back of the device.

2. Plug the power adapter into an available socket.

Note: For International use, you may need to change the AC

power adapter cord. You must use a power cord set that

has been approved for the receptacle type and electrical

current in your country.

Warning

Please exercise caution when using power tools. Also,
install this unit away from damp or wet locations, or i n
close proximity to very hot surfaces. These types of
environments can have a detrimental effect on the
converter and cables. An ideal location is a lightly
cooled place such as a typical equipment room.
Because invisible laser radiation may be e mitted from
the aperture of the port when no cable is connected,
avoid exposure to laser radiation a nd do not stare int o
open apertures.

2. Check the power LED on the rear of the Converter

3. when the device is powered on to verify that

power is applied. If not, check that the power

cable is correctly and securely plugged in.

4.

Connecting Fiber Cable

When connecting fiber cable to a 100BASE-FX port

on the Converter, be sure the correct type - ST or SC

or WDM - connector is used. Follow the steps below

to properly connect fiber cable:

1. Remove and keep the ST/SC/WDM port's rubber

cover. When not connected to a fiber cable, the

rubber cover should be replaced to protect the

optics.

2. Check that the fiber terminators are clean. You

can clean the cable plugs by wiping them gently

with a clean tissue or cotton ball moistened with a

little ethanol. Dirty fiber terminators on fiber optic

cables will impair the quality of the light

transmitted through the cable and lead to

degraded performance on the port.

3. Connect one end of the cable to the ST/SC/WDM
