Troubleshooting
• Verify that you are using the right power adapter ( DC 5V, 2.5 A ).
Using a power adapter with DC output greater than 5V could result
in damage to the unit and/or personal injury.
• Check the configuration DIP switch. It must be set in the same
operation mode as its link partner.
• Confirm the proper UTP/Fiber cable is being used. The Single Mode
converter must use Single Mode fiber optic cable.
Hardware Description
The Front Panel
The Front Panel of the 10/100TX/100FX converters consists of one
RJ-45 Port ( Auto MDI/MDIX ), 6 LED Indicators (TX SPD, LK/ACT,
FDX/COL, Fiber LK/ACT, FDX and PWR ) and one fiber 100Base-FX
Port.
Ports
• RJ-45 Port (Auto MDI/MDIX): the Ethernet RJ-45 will features Auto-
Sensing for 10Base-T or 100Base-TX connections and Auto
MDI/MDIX which is basically an auto crossover feature. This
means you can connect to another Switch or workstation without
changing to a crossover cable.
• Fiber Port: This port is for the 100 Base-FX connection. Unicom
provides three different styles of fiber connectors (SC/ST, Multi-
Mode or SC, Single-mode).
