Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which are connected
with lasers. To protect your eyes against radiation harm, never stare into an open fiber-optic port.
Step 1: Locate the Rx and Tx ports on the interface card. Connect them to another
device with two optical fibers: Rx to Tx and Tx to Rx.
Step 2: Power on the router and check the behavior of the LINK LED on the card panel:
ON means an Rx link is present and OFF means the opposite. In the latter case, check
the line status.
