Introduction

The MC100FX-SC media converters allow seamless integration between a (Fast) Ethernet network using unshielded twisted pair (UTP) copper cabling and a fiber network.
The MC100FX-SC2 media converter comes with a built-in multimode fiber transceiver module with SC connector that can be used for distances of up to 2km.
The MC100FX-SC30 media converter comes with a built-in single mode fiber transceiver module with SC connector that can be used for distances of up to 30km.

MC100FX-SC2/30 User’s Guide
Use the LEDs to quickly check status and the DIP switches to set transmission settings and “link loss forwarding”.

Key Features

Each media converter has the following key features:
Converts speed and media type Built-in fiber transceiver module with SC connector Auto-crossover Ethernet port (auto MDI/MDI-X detection allows
use of either straight-through or crossover Ethernet cables)
Auto-negotiating Ethernet port (can detect and adjust to the
optimum speed (10/100Mbps) and mode (full duplex or half duplex) of the connected device)
LED status display DIP switches to configure fiber link negotiating defaults, Link
Loss Forwarding and store-and-forward switching
Link Loss Forwarding to notify the peer link if a link goes down

Fiber Modes

Multi-Mode Fiber (MMF) allows more than one mode of light to propagate through the cable at one time. It is usually used as horizontal cable (cable from your equipment room to each designated outlet or
8
MC100FX-SC2/30 User’s Guide
work area) and sometimes as backbone cable (between equipment closets or rooms).
Light in a Single-Mode Fiber (SSF) travels straight down the fiber and does not bounce off the surrounding cladding as it travels. This is most commonly used by telephone companies and as backbone cable.

Applications

In the following figures, “A” is the media converter, “B” is a 10/100 Mbps Ethernet switch and “C” is a layer-3 switch with 100Mbps fiber module.

MC100FX-SC2 MMF Applications

Use MC100FX-SC2 media converter for multimode fiber connections for distances of up to 2km.

2Km

MC100FX-SC30 SMF Application

Use the MC100FX-SC30 media converter for single mode fiber connections for distances of up to 30km.

Hardware

The media converter can be placed on a desktop. Make sure that there is proper heat dissipation from and adequate ventilation around the device. Do not place heavy objects on the media converter.

Front Panel

The front panel consists of an RJ-45 port for 100 Mbps UTP connections, LED indicators, DIP switches and a built-in fiber transceiver with SC connector.

100Base-TX Port

Connect an Ethernet cable from a switch to this port. This port is auto­negotiating and auto-crossover.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100Mbps) and duplex mode (full duplex or half duplex) of the connected device. An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover Ethernet cable.

The following table describes the LEDs in detail.

or the fiber link is down.

Link Loss Forwarding

Without Link Loss Forwarding, if one side of a link fails (), the other side will keep on transmitting packets () and wait for responses that will never arrive.
With Link Loss Forwarding, a link down () detected on the Ethernet port will force a link down on the fiber port and vice-versa. The up link () will stop transmitting and turn "off" as soon as the remote link is down.
12
MC100FX-SC2/30 User’s Guide

DIP Switches

All DIP switches are off by default.
DIP Switch 1
DIP Switch 2
DIP Switch 3
DIP Switch 4
The Ethernet link is auto-negotiating when the switch is off. Turn it on to force the Ethernet link to be up at only 100Mbps in full duplex mode.
The fiber link operates in full-duplex mode when the switch is off. Turn it on to have the fiber link operate in half-duplex mode.
Turn this switch on to enable Link Loss Forwarding. A message is sent to the Ethernet port if the fiber link goes down (thus forcing the Ethernet link down) and vice-versa.
When this switch is off, the Ethernet port uses a store-and­forward switching scheme, in which incoming data frames are first stored in buffer memory and checked for errors before being forwarded. Turn this switch on to have the Ethernet port operate in pure converter mode in which the port forwards the received data frame immediately after being received (without error checking).
Do not turn a DIP switch on or off when a port is transmitting
or receiving data as it may cause data error or loss.

Fiber Transceiver

The MC100FX-SC2 comes with a built-in multimode fiber transceiver with SC connector that can be used for connections of up to 2km.
The MC100FX-SC30 comes with a built-in single mode fiber transceiver with SC connector that can be used for connections of up to 30km.
SFP transceiver modules are dust sensitive. Avoid getting dust and other contaminants into them.
SFP transceivers are equipped with a Class 1 laser, which emits invisible radiation. To avoid possible eye injury, do not look into an operating fiber-optic module’s connectors. Laser radiation is also present when the media converter is turned on.

MC100FX-SC2/30 User’s Guide
Use DIP switch 2 to change the default fiber connection
settings.

Rear Panel

The rear panel contains a power port. Connect the included power adapter (9V DC voltage with minimum 0.7A current) to the port labeled 9VDC and connect the power adaptor to a power supply (outlet).

Troubleshooting

Use the LEDs to identify possible problems and then take corrective action.
PROBLEM POSSIBLE CAUSES AND REMEDIES
The PWR LED is off
The 100M LED is off
The LNK/ACT (Ethernet) LED is off
Make sure you are using the supplied power adaptor and that it is plugged in to an appropriate power source. Check that the power source is turned on.
If the problem persists, you may have a hardware problem. In this case, you should contact your local vendor.
Check if the media converter has a connection with a 10Mbps Ethernet device.
Check the Ethernet cable connection between the media converter and the Ethernet device. The distance between them should not be more than 100 meters
Check for faulty Ethernet cables.
If the connected Ethernet device does not support auto­negotiating, turn on DIP switch 1 to force a 100 Mbps full-duplex link.
If Link Loss Forwarding is enabled (DIP switch 3 is on), then check if the fiber link is down (thereby forcing the Ethernet link down).
Check the Ethernet cable connection between the media converter and the Ethernet device. The distance between them should not be more than 100 meters
Check for faulty Ethernet cables.
Check that the Ethernet device supports auto­negotiating at half/full duplex and 100MBps speed.
If Link Loss Forwarding is enabled (DIP switch 3 is on), then check if the fiber link is down (thereby forcing the Ethernet link down).

The FDX/COL (Fiber) LED is off
The RJ-45 port is operating in half-duplex mode or the Ethernet link is down. See above for possible causes and remedies.
Check the fiber cable connection between the media converter and the remote device. Check that the distance between them does not exceed limits for single mode (MC100FX-SC30) or multi mode fiber (MC100FX-SC2).
Check for faulty cables.
Check what duplex mode the remote device supports and then set DIP switch 2 (off for full-duplex and on for half-duplex).
If Link Loss Forwarding is enabled (DIP switch 3 is on), then check if the Ethernet link is down (thereby forcing the fiber link down).
The fiber port is operating in half-duplex mode or the fiber link is down. See above for possible causes and remedies.
