3-10z For a 10/100/1000 Mbps port, connect it to a PC or another router using a crossover cable or to aHub or LAN switch using a straight-through cable.Step 2: View the LINK LED of the Ethernet interface: ON means a link is present. OFF means no link ispresent; check the line for the cause2) Connecting optical Ethernet interface cable.When connecting optical fibers, observe the following:z Do not over-bend the fiber. Its curvature radius must be greater than 10 cm (3.9 in.).z Ensure that the Tx and Rx ends are correctly connected.z Ensure that the fiber ends are clean.Laser danger! Invisible laser radiation may be emitted from the fiber-optic ports which are connectedwith lasers. To protect your eyes against radiation harm, never stare into an open fiber-optic port.Follow these steps to connect a 10/100/1000 Mbps optical interface:Step 1: Use two fibers to connect the Rx and Tx ends of the interface to another device: Rx to Tx, and Txto Rx.Step 2: Power on the router and view the LINK LED of the Ethernet interface. ON means the Rx link ispresent. OFF means no Rx link is present; check the line for the cause.Connecting AUX to a ModemAUX portAUX is an RS232 asynchronous serial interface, which can back up a WAN interface and provide dialconnection. In case of console failure, AUX can function as a console interface.AUX cableAUX cable is an eight-wire shielded cable. At one end of the cable is an RJ-45 connector for connectingthe console port on the router. At the other end are DB-9 (male) connector and DB-25 (male) connector.You can plug either of them into the serial port on a modem as needed.
