I NTR ODUC TION
Thank you for choosing the 10/100BASE Fast Ethernet
Media Converter, The Converter introduced here
provides one channel media conversion between
10/100BASE-TX and 100BASE-FX.
About Media Converter
The Media Converter is a network technology specified
by IEEE 802.3 10BASE-T, IEEE802.3u 100BASE-TX,
100BASE-FX standards.
Product Features
 One-channel media conversion between
10/100BASE-TX and 100BASE-FX
 Fiber media allows: multi-mode fiber using SC, LC
or MT-RJ connector; single-mode fiber using SC
connector
 Auto negotiation of speed and duplex mode on TX
port
 Auto MDI-X on TX port
 One slide switch for configuring fixed half/full
duplex modes
 Store-and-forward mechanism
 Back-pressure & IEEE802.3x compliant flow
control
 Full wire-speed forwarding rate
 Front panel status LEDs
 Used as a stand-alone device or with a chassis
 Hot-swappable when used with a chassis

I NSTALLATION
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
receptacle on the rear panel of the converter, and
then attach the plug into a standard AC outlet
with a voltage range from 100 to 260 Vac.
Sliding Switch
There is a sliding switch for duplex mode setting for
fiber port. Refer to the table below for more details.

Connecting to Power
3. This Converter is a plug-and-play device.
4. 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.
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.
