Installation
To install your converter, please see the following procedures:
• MDI / MDI-X Connection
• Switch Settings
• Network Setup With Converter
MDI / MDI-X Connection
The auto-MDI function alleviates the worry of cable type configuration
when connecting the converter to a 10/100Base-TX device. The
converter will automatically detect the connection information and
establish the optimum setting.

Important:
In order to configure switches 2, 3 and 4, switch 1 (autonegotiation) must firstly be disables
Notes:
• Setting the duplex mode is feasible while the media
converter is“on-line”.
• All models in this series feature the above set of DIP
swiches.

Link Fault Signaling (LFS)
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. To fully appreciate the 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 protocals. By default, transmission of data will travel via the
primary link. Once a fault has been detected by the converter,
transmission will automatically be switched to the secondary link,
resulting in ‘non-stop’ network connectivity.
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.

Loopback Test
This converter features dip switches to activate local and remote
loopback 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
Please make sure that the cables are connected properly before
getting started. Conduct either the local or remote test and not
both at the same time.
Note: Deactivate both local and remote loopback test
functions for mormal converter operations

LED Indicators
This converter has LED indicators located at the front of the device.
The LEDs have been designed to give easy at-a-glance network
status, and provides ‘real-time’ connectivity information. Please see
below for an interpretation of their functions:
Unit LEDs: PWR: Red light - indicates normal power
Port LEDs: FDX: Amber light - indicates full-duplex
mode
COL: Flashing amber light - indicates
collision
LNK: Green light - indicates receiving link
pulses from a compliant device
ACT: Flashing green light - indicates
packets are being transmitted or
received
100: Green light - indicates packets
transmitted at 100 Mbps

Appendix B
Converter Mounting
This converter can be placed in any location that will make its
installation convenient. If you place the converter on a horizontal
surface or on top of existing networking equipment, please affix the
four rubber pads included in the package.
This converter can also be mounted on a vertical surface. Simply
use the underside of the unit as a template to measure and mark
out the position of the holes on to the surface where the unit is to
be installed. Then use two screws to mount the converter firmly in
place.
Please exercise caution when using power tools. Also, install this
unit away from damp or wet locations, or in 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.

Introduction
Product Overview
The Enhanced 10/100 to 100Base-FX Switching Converter is
designed for large workgroups who demand higher speed and wider
bandwidth. This converter allows migration and expansion from a
copper-based Ethernet to a fiber optic Fast Ethernet.
It features automatic MDI detection setting. This feature 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 media converter is equipped with an RJ-45 port and a fiber
optic ST or SC port. This allows it to quickly integrate a 10/100BaseTX network into a 100Base-FX (fiber) network.
It features DIP switches for manual half or full-duplex mode
configuration on the fiber port. In full-duplex mode, this converter
has the ability to support distances of up to 2 kilometers for multimode fiber and up to 60 kilometers for long-haul single mode fiber
between a LAN switch, file server or another networking device.
