Installation Manual

Starting and Configuring the Router

Step 1: Connect one end of the Ethernet cable to an Ethernet port on the router and the other end to another device.

For a 10/100 Mbps port provided by the RPU, connect it to a PC or another router using a crossover cable or to a Hub or LAN switch using a straight-through cable. For a 10/100/1000 Mbps Ethernet port provided by the RPU2, either straight-through or crossover cable can be used to connect to a Hub or LAN switch because MDI/MDIX autocrossover is supported.

Step 2: View the LINK LED of the Ethernet interface: ON means a link is present. OFF means no link is present; check the line for the cause.

1)Connect the fiber-optic Ethernet interface cable

Caution:

In connecting optical fibers, observe the following:

zDo not over-bend the fiber. Its curvature radius must be greater than 10 cm (3.9 in.).

zEnsure that the Tx and Rx ends are correctly connected.

zEnsure that the fiber ends are clean.

Warning:

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.

Follow these steps to connect a 10/100/1000 Mbps fiber-optic interface on the RPU2:

Step 1: Use two fibers to connect the Rx and Tx ends of the interface to another device: Rx to Tx, and Tx to Rx.

Step 2: Power on the router and read the LINK LED of the interface: ON means the Rx link is present. OFF means no Rx link is present; check the line for the cause.

3.9 Connecting the Router to a WAN

Many types of WAN interfaces are available with the Router 6000 and the one provided by the main control boards is an AUX interface. The following subsections describe how to connect it. For connecting the WAN interface on a FIC, refer to the relevant contents in the chapter “FICs”.
