One-Channel Media Converter
Ports
The Converter provides one TX port and one FX port. For the FX port,
it provides options of
Multi-mode fiber using SC, ST, VF-45, MT-RJ or LC connector or
Single-mode fiber using SC or ST connector or
WDM fiber using single SC connector
For the TX port, it uses RJ-45 connector and auto senses the speed of
10/100Mbps.
Port Settings
Port settings are made very simple by means of a DIP (Dual Inline
Package) switch at the rear panel of the module.

DIP switch
There are six pins on the DIP switch for port settings. Refer to the table below for more details.

y First, disconnect the converter from the power. Then toggle Pin 2 of the DIP switch to the up position
to enable the forced mode for TX port.
<NOTE> Pin 2 must be toggled up prior to speed and duplex mode settings
manually.
y Toggle down Pin 3 to force the TX port at the speed of 100Mbps. Or toggle up Pin 3 for 10Mbps
speed.
y Toggle down Pin 4 to force the TX port at full duplex mode. Or toggle up Pin 4 for half duplex mode.
y Toggle down Pin 5 to force the FX port at full duplex mode. Or toggle up Pin 5 for half duplex mode.
y Toggle up Pin 1 to disable the link-fault-pass-through.
y Connect the converter to the power again. The new setting will come into effect then.

Link-Fault-Pass-Through
Connect the FX ports of two Media Converter A and B through the fiber
cable.
1. Link Fault of the FX port:
A Link Fault condition will be sensed on the TX port whenever the
media converter detects a Link Fault condition on the FX port. Thus,
the 100, LNK/ACT, and FDX/COL LEDs of the media converter
would be off.
2. Link Fault of the TX port of the Media Converter A:
The Media Converter A: A Link Fault condition will be sensed on
the FX port whenever the media converter detects a Link Fault
condition on the TX port. Thus, the 100, LNK/ACT, and FDX/COL
LEDs of the TX port of the Media Converter A would be off.
The Media Converter B: A Link Fault condition will be informed to
the FX port of the Media Converter B. Then a Link Fault condition
will be sensed on the TX port of the Media Converter B whenever
the Media Converter B detects a Link Fault condition on the FX
port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the Media
Converter B would be off.

Installation
This chapter gives step-by-step installation instructions for the
Converter.
Selecting a Site for the Equipment
As with any electric device, you should place the equipment where it
will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select should
meet the following requirements:
z The ambient temperature should be between 32 and 113 degrees Fahrenheit (0 to 45 degrees
Celsius).
z The relative humidity should be less than 95 percent, non-condensing.
z Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards for
IEC 801-3, Level 2 (3V/M) field strength.
z Make sure that the equipment receives adequate ventilation. Do not block the ventilation holes
on each side of the equipment.
z The power outlet should be within 1.8 meters of the product.
Connecting to Power
y This Converter is a plug-and-play device.
y Connect the supplied AC to DC power adaptor to the receptacle on the rear panel of the converter,
and then attach the plug into a standard AC outlet.
Installing in a Chassis
The Converter can be fit into any of the expansion slots on a special
designed chassis.
y First, install the converter onto a carrier supplied with the chassis:
Step 1- Unscrew the carrier from the desired expansion slot on the chassis.
Step 2- Fit the converter onto the carrier.
y When the converter is completely seated onto the carrier, insert the carrier to the guide rails of the
expansion slot.
y Carefully slide in the carrier until it is fully and firmly fit the chassis. Fasten the screws onto the
carrier.
<NOTE> Never insert any converter into the chassis directly without using the
supplied carriers. The carriers allow secure and consistent placement
of the converters into the chassis’ backplane without causing any
damage.
