	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.
	WARNING: Because invisible laser radiation may be emitted from the aperture of
w an optical port when no fiber is connected or the dust cap is removed, do not
	stare into the open aperture.
	Replace the dust cap when no fiber is connected to the optical port.
