INTRODUCTION

Thank you for choosing the 1000Base Gigabit Ethernet
Media Converter, The Converter introduced here provides
one channel media conversion between 1000BASE-TX and
1000BASE-FX.

About Media Converter

Media Converter is a network technology specified by IEEE

802.3ab and IEEE 802.3z 1000BASE-TX/FX standards.

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:

1. The ambient temperature should be between 32 and

104 degrees Fahrenheit (0 to 40 degrees Celsius).

2. The relative humidity should be less than 90 percent,

non-condensing.

3. Surrounding electrical devices should not exceed the

electromagnetic field (RFC) standards for IEC 801-3,
Level 2 (3V/M) field strength.

4. Make sure that the equipment receives adequate

ventilation. Do not block the ventilation holes on each
side of the switch or the fan exhaust port on the side or
rear of the equipment.

5. The power outlet should be within 1.8 meters of the

switch.

Connecting to Power

1. This Converter is a plug-and-play device.

2. Connect the supplied AC to DC power adaptor with a

power voltage of 7.5Vdc/1.5Amp to the DC-Jack on
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.

5

y First, install the converter onto a carrier supplied with
the chassis:

Step 1- Unscrew and pull out the media converter board.
Step 2- Plug in the media board to any of the vacant slot.
Step 3- Fit the converter onto the carrier and use the screw

to secure it.

Monitoring the Converter through
Management Module

There is a management module that can control this media
converter through the chassis system, this media converter
can be controlled through Web Browser, SNMP and terminal
emulation program.
The management module will detect the default reset on the
DIP switches and display out the status, also the

management module can control the function through the
chassis system.

6

NOTE: To control the function in a working station, need to collocate together with optional Chassis

System and Management Module.

LED Indicator

The LED indicators give you instant feedback on status of the
converter:

Link Pass Through Function

LLCF (Link Loss Carry Forward)

When a device connected to the converter and the TP line loss
the link, the converter’s fiber will disconnect the link of
transmit, so that the other ends will know that there is a
linkage error on this end. And when the Fiber line loss the
link, the converter’s TP will disconnected, and the other end
will know that there is linkage problem exist.

There is a default LLCF setting on this converter.

LLR (Link Loss Return)

When a device connected to the converter and the fiber line
loss the link, the converter’s fiber will disconnect the link of
transmit.

There is a switch to enable or disable the function of the
media converter.

Switch

There is a two pin DIP switch on the module which define as
switch 1 and switch 2:

Switch 1: Fiber mode switch

When the switch was turned to “On”, it means that the
fiber was turned to forced mode, and “Off” for
auto-negotiation mode.

Note: Be sure the opposite end is using the same setting (forced or Auto-negotiation).
And when using two converters at the same time, the two conv erters MUST set to
forced mode.

Switch 2: LLR

When the switch was turned to “On”, it means that the
LLR was enabled and “Off” for disabled.

Note: When using two converters, don’t enable the both device’s LLR function at the

9

same time.
