MC100FX-SC2/30 User’s Guide Introduction The MC100FX-SC media converters allow seamless integration between a (Fast) Ethernet network using unshielded twisted pair (UTP) copper cabling and a fiber network. The MC100FX-SC2 media converter comes with a built-in multimode fiber transceiver module with SC connector that can be used for distances of up to 2km.
MC100FX-SC2/30 User’s Guide Use the LEDs to quickly check status and the DIP switches to set transmission settings and “link loss forwarding”.
MC100FX-SC2/30 User’s Guide work area) and sometimes as backbone cable (between equipment closets or rooms). Light in a Single-Mode Fiber (SSF) travels straight down the fiber and does not bounce off the surrounding cladding as it travels. This is most commonly used by telephone companies and as backbone cable. Applications In the following figures, “A” is the media converter, “B” is a 10/100 Mbps Ethernet switch and “C” is a layer-3 switch with 100Mbps fiber module.
MC100FX-SC2/30 User’s Guide 30Km Hardware The media converter can be placed on a desktop. Make sure that there is proper heat dissipation from and adequate ventilation around the device. Do not place heavy objects on the media converter. Front Panel The front panel consists of an RJ-45 port for 100 Mbps UTP connections, LED indicators, DIP switches and a built-in fiber transceiver with SC connector.
MC100FX-SC2/30 User’s Guide 100Base-TX Port Connect an Ethernet cable from a switch to this port. This port is autonegotiating and auto-crossover. An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100Mbps) and duplex mode (full duplex or half duplex) of the connected device. An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover Ethernet cable. LED Indicators The following table describes the LEDs in detail.
MC100FX-SC2/30 User’s Guide LED LNK/ACT (Fiber) FDX/COL (Fiber) STATUS DESCRIPTION Green The media converter fiber link is up. Blinking The media converter is transmitting or receiving on the fiber link. Off The media converter fiber link is down. Orange The fiber port is operating in full-duplex mode. Blinking Packet collisions are occurring on the fiber port. Off The fiber port is operating in half-duplex mode or the fiber link is down.
MC100FX-SC2/30 User’s Guide DIP Switches All DIP switches are off by default. DIP Switch 1 The Ethernet link is auto-negotiating when the switch is off. Turn it on to force the Ethernet link to be up at only 100Mbps in full duplex mode. DIP Switch 2 The fiber link operates in full-duplex mode when the switch is off. Turn it on to have the fiber link operate in half-duplex mode. DIP Switch 3 Turn this switch on to enable Link Loss Forwarding.
MC100FX-SC2/30 User’s Guide Use DIP switch 2 to change the default fiber connection settings. Rear Panel The rear panel contains a power port. Connect the included power adapter (9V DC voltage with minimum 0.7A current) to the port labeled 9VDC and connect the power adaptor to a power supply (outlet).

MC100FX-SC2/30 User’s Guide Troubleshooting Use the LEDs to identify possible problems and then take corrective action. PROBLEM POSSIBLE CAUSES AND REMEDIES The PWR LED is off Make sure you are using the supplied power adaptor and that it is plugged in to an appropriate power source. Check that the power source is turned on. If the problem persists, you may have a hardware problem. In this case, you should contact your local vendor.
MC100FX-SC2/30 User’s Guide PROBLEM POSSIBLE CAUSES AND REMEDIES The FDX/COL (Ethernet) LED is off The RJ-45 port is operating in half-duplex mode or the Ethernet link is down. See above for possible causes and remedies. The LNK/ACT (Fiber) LED is off Check the fiber cable connection between the media converter and the remote device. Check that the distance between them does not exceed limits for single mode (MC100FX-SC30) or multi mode fiber (MC100FX-SC2). Check for faulty cables.
