Connecting the Interface Step 1: Connect one end of the cable to the Ethernet interface on the router and Cable the other end to another device.

Step 2: Power on the router and check the behavior of the LINK LED on the panel. ON means a link is present and OFF means no link is present. In the latter case, check the line status.

FIC-1GEF/FIC-2GEF

Introduction FIC-1GEF/FIC-2GEF, the 1-port/2-port 1000Base-SX/1000Base-LX GE fiber

interface card, is used for router-to-LAN communication.

The cards support:

■Five types of 1000Base-SX/1000Base-LX SFP modules: multi-mode short-haul (850 nm), single-mode medium-haul (1310 nm), single-mode long-haul (1310 nm), single mode long-haul (1550 nm), and single-mode ultra-long haul (1550 nm)

■Operation at 1000 Mbps

■Full duplex
