CABLING

What's a Network Cable?

Network cables connect PCs in an Ethernet network, so they can share data and resources like printers and Internet access.

Since cables transmit data to and from your PCs, knowing how to use the right cables is the key to enjoying fast, reliable connections.

High-speed cable and DSL modems also use network cables to connect you to the Internet, which is simply one huge global network.

Network cables come in different types and grades, called "categories." Category 5, called "Cat 5" for short, is the most reliable and commonly used type of network cable today. You can buy them at any retail computer store for just a few dollars.

Standard Category 5 "Cat 5" network cables

Cat 5 cables are an example of "twisted-pair cabling," because the wires inside are twisted into pairs.

Cat 5 cables are tipped with RJ-45 connectors, which fit into RJ-45 ports.

RJ-45 ports are the most basic, common type of network interface used to connect two PCs together to share resources. Cable modems and DSL modems also use RJ-45 ports to connect you to the Internet.

RJ-45 ports can be found on network adapters, hubs, switches, your EtherFast Cable/DSL Router.

Straight-Through and Crossover Cables

To tell whether your cables are straight-through or crossover, hold the ends of your cable side by side, with both spring clips facing down.

Straight-through cables have the same order of wire colors in each tip, when held side by side. Most connections use a straight-through network cable.

Crossover cables, on the other hand, show different wire colors when held side by side.

If you are using homemade network cables instead of the store-bought variety, make sure that your RJ-45 ends are securely attached, and that your wires are properly pinned out according to the diagrams above.

What You Need For Your Set-Up

Before setting up your Router, make sure that you have enough network cables to connect your modem to your Router, and each of your PCs to your Router or network.

You'll also need a network adapter installed in each of your PCs.

Some cable or DSL modems use a crossover cable to connect to the Router, so check to see which type of cable your modem uses.

Whenever you finish connecting two pieces of hardware, always check to see that the matching Link LEDs light up. For example, your WAN Link LED lights up to mean that your modem is successfully connected to your Router. There is probably also a Link LED on your network adapter, found on the rear panel of your PC.

It is essential that you use the right cables in connecting your EtherFast Cable/DSL Router, and that you connect all your hardware with securely crimped cabling and properly pinned out ends.
