Connecting the Interface To connect a PC or another router, use a crossover cable; to connect a LAN Switch Cable or HUB, use a straight-through cable.

Step 1: Connect one end of the cable to the Ethernet port and the other end to the peer device;

Step 2: Check the status of LINK LED on the 1GBE panel: ON means the link is connected and OFF means the link is not connected. In the latter case, check the line.

MIM-1GEF/MIM-2GEF

Module

Introduction MIM-1GEF/MIM-2GEF is short for 1/2-port 1000Base-SX/1000Base-LX GE fiber interface module, where GE is short for Gigabit Ethernet and F for fiber, indicating optical fiber interface. MIM-1GEF/MIM-2GEF is used for the communication between router and LAN.

MIM-1GEF/MIM-2GEF supports:

■Five types of 1000Base-LX/1000Base-SX SFP removable 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)

■1000 Mbps interface rate

■Full duplex
