example, PC or router) to a HUB or LAN switch. The cables delivered with the router are straight-through cables.

zCrossover cable: The wires are crimped in the RJ-45 connectors at both ends in different orders. The cable is used for connecting two terminal devices (for example, PC and router). You can make cables as needed.

Note:

In making network cables, shielded cables are preferred for electromagnetic compatibility sake.

The interface cables in the standard package of Router 2-Port 10/100 cards are straight-through cables.

4.1.5 Connecting the Interface Cable

Step 1: Plug one end of the cable to an Ethernet port on the router and another end to the device to be connected. (For a PC or router, use a straight-through cable; for a HUB or LAN switch, use a crossover cable.)

Step 2: Power on the router and check the on the FIC-FE panel: ON means that a link is present and OFF means that no link is present. In the latter case, check the line status.

Caution:

Before you connect a port, read its label carefully; a wrong connection can cause damages to the interface card and even the device.
