Troubleshooting
• Verify that you are using the right power adapter, DC 5V, 2A
(minimum). Using a power adapter with DC output greater than 5V
could result in damage to the unit and/or personal injur y.
• Confirm the proper UTP/Fiber cable is being used. The Single Mode
conver ter must use Single Mode fiber optic cable.
Optical Fiber Spec
The following table shows the optical fiber specification:
Hardware Description
The Front Panel
The Front Panel of the 10/100/1000T/1000SX/LX conver ters con-
sists of one RJ-45 Por t ( Auto MDI/MDIX ), 6 LED Indicators (SPD,
LK/ACT, FDX/COL, and PWR ) and one fiber 1000Base-SX/LX Por t.
Ports
• RJ-45 Por t (Auto MDI/MDIX): the Ethernet RJ-45 will features Auto-
Sensing for 10/100/1000Base-T 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 Por t: This por t is for the 1000Base-SX/LX connection and is
available in the SC format in Multi- and Single mode.This fiber
por t does not suppor t auto-negotiation.
