DMC-300SC 10/100BaseTX to 100BaseFX Media Converter
INTRODUCTION
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
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:
- The ambient temperature should be between 32 and 104 degrees Fahrenheit (0 to 40 degrees Celsius).
- The relative humidity should be less than 90 percent, non-condensing.
- Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards for IEC 801-3, Level 2 (3V/M) field strength.
- 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.
- The power outlet should be within 1.8 meters of the switch.
Connecting to Power
-
This Converter is a plug-and-play device.
-
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 -
This Converter is a plug-and-play device.
-
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.
LED Indicator
The LED indicators give you instant feedback on status of the converter:
| LEDs | State | Indication |
|---|---|---|
| Power (PWR) | Steady | Power on |
| Off | Power off |

(100)
| Steady| Runs at 100Mbps on TX port
Off| Runs at 10Mbps on TX port
TX Port (TX) FX Port (FX) FDX/COL
| Steady (FDX)| Connection in full duplex mode
FDX stands for FULL-DUPLEX
Lights off| Connection in half duplex mode
Blinking (COL)| Data collision
TX Port (TX) FX Port (FX) LINK/ACT
| Steady
(LINK)
| A valid network connection established
Lights off| Not Linking
Blinking (ACT)| Transmitting or receiving data
ACT stands for Activity
