Introduction
The Gigabit Ethernet Media Converter provides one channel for media conversion
between 1) 1000Base-T and 1000Base-SX/LX with link-fault-pass-through function
or 2) 1000Base-SX/LX and 1000Base-LX. It can be used as a stand-alone device or
with a standard 19” chassis as shown below.

Product Features
yOne-channel media conversion between:
1000Base-T and 1000Base-SX/LX, 1000Base-SX/LX and 1000Base-LX
yFiber media allows either:
Multi-mode fiber, Single-mode fiber, or WDM Single-mode fiber
yFull wire-speed forwarding rate
yFront panel status LEDs
yUsed as a stand-alone device or with a chassis
yHot-swappable when used with a chassis
yMake sure to make a connection to the TX port before make a
connection to the fiber port, a link condition will be sensed on the fiber
port whenever the media converter detects a link condition on the TX
port
1000T ↔1000SX/LX Media Converter
yThere are two pins on the DIP switch of the 1000Base-T and 1000Base-
SX/LX one-channel media converter:
♦Toggle up the pin on the left-hand side to let the fiber port auto
detect duplex mode.
♦Toggle down the pin on the left-hand side to force the fiber port to
full duplex mode.
♦Toggle up the pin on the right-hand side to disable the link-fault-
pass-through function.
♦Toggle down the pin on the right-hand side to enable the link-fault-
pass-through function.

Physical Ports
1000T ↔1000SX/LX Media Converter
This converter provides one TX port and one FX port. For the FX port, it provides
options of multi-mode, single-mode, or WDM single-mode fiber. For the TX port, it
uses RJ-45 connector and supports auto MDIX for uplink purpose.
1000SX/LX ↔1000LX Media Converter
This converter provides two FX ports:
1) One multi-mode/single-mode fiber port and one single-mode fiber port.
2) One multi-mode/WDM single-mode fiber port and one WDM single-mode fiber
port.
Port Status LEDs
The LED indicators give you instant feedback on status of the converter:

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 113 degrees Fahrenheit
(0 to 45 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 of the equipment.
- The power outlet should be within 1.8 meters of the product.
Connecting to Power
This Converter is a plug-and-play device.
Step 1: Connect the supplied AC to DC power adapter to the receptacle at
the back of the converter.
Step 2: Attach the plug into a standard AC outlet.
Installing in a Chassis
The Converter is designed to fit into any of the expansion slots on a rackmount
chassis.
Step 1: Unscrew the carrier from the desired expansion slot on the chassis.
Step 2: Fit the converter onto the carrier.
Step 3: When the converter is completely seated onto the carrier, insert
the carrier to the guide rails of the expansion slot.
Step 4: Carefully slide in the carrier until it is fully and firmly fit the chassis.
Step 5: Fasten the carrier to the chassis by the screws.
<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.
