1. Introduction The 10/100BASE-TX to 100BASE-FX media converter series provides a media conversion allowing high-speed integration of fiber optic and twistedpair segments. With 10BASE-T and 100BASE-TX support, the converters provide seamless translation between Ethernet and Fast Ethernet networks. A complete set of LEDs allows for quick status verification. 1.

1.4 Special Functions Auto MDI/MDI-X Function This function allows the TP port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to MDI-X connection with the remote connected device automatically. Auto-negotiation Function The TP port is featured with auto-negotiation function and full capability. It performs a negotiation process for the speed and duplex configuration with the connected device automatically when each time a link is being established.
Link Fault Pass Through Function This function supports a link fault detected on the TP port will force a link down on the FX port. Similarly, a link fault detected on the FX port will also force a link down on the TP port. As illustrated in the following figure, this function allows to pass TP link fault to the remote link partner and makes the converter like a TP cable extender.
2. Installation 2.1 Unpacking Check that the following components have been included: • Product CD • 10/100 Media Converter • One AC power adapter If any item is found missing or damaged, please contact your local reseller for replacement. 2.2 Mounting the Device Desktop Mounting The media converter can be mounted on a desktop or shelf. Make sure that there is proper heat dissipation from and adequate ventilation around the device. Do not place heavy objects on the device.
2.3 Applying Power Before you begin the installation, check the AC voltage of your area. The AC power adapter which is used to supply the DC power for the unit should have the AC voltage matching the commercial power voltage in your area. The AC Power Adapter Specifications AC input power: AC power voltage of your area, options Rated AC120V/60Hz DC7.5V 1A Rated AC230V/50Hz DC7.5V 1A Rated AC100V/50-60Hz DC7.5V 1A Rated AC100V/50-60Hz DC5V 1A Rated AC240V/50Hz DC7.
Network Cables 10BASE-T: 2-pair UTP Cat. 3,4,5 , EIA/TIA- 568 100-ohm STP 100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568 100-ohm STP Link distance: Up to 100 meters 2.5 Making FX Port Connection FX port operates on 100Mbps and full duplex (factory default). A variety of fiber options is provided as follows: Duplex Fiber Series Model Connector EM4000 SC EM4001 ST Wavelength Fiber Max.

2.7 Smart Forwarding The media converters are featured with a smart forwarding design. The following table lists the forward method used in different TP to FX conversions: TP port to/from FX port Forward method 10BASE-T to 100BASE-FX Store and forward 100BASE-TX to 100BASE-FX Direct conversion The converter can change to direct conversion automatically when it detects same speed on both TP port and FX port.
