Step 2: Locate the Rx and Tx fiber-optic interfaces on the interface card. Use two
fibers to connect the FIC-1POS to another device: Rx to Tx and Tx to Rx.

Step 3: Power on the device and check the LINK LED on the FIC-1POS panel: ON
means the Rx link is present and OFF means the opposite. In the latter case, check
the line status.
