Lan cabling pdf

With all this in mind, the main consideration in the early stages of LAN planning is what size it will be and what services it will provide. While a LAN featuring ten nodes can be set up in as little as one day, a larger network is a bigger undertaking.

For each special service that a LAN offers — such as printing, sophisticated software or email — it will need a server.

A single server can provide multiple types of services, though heavy duty applications often require a dedicated server. Servers may require specialized cooling and cabling arrangements, but having redundant servers allows you to maintain your services if the network experiences trouble. Likewise, using multiple servers may allow you to grow your network more easily. Once the purpose of the network is well understood, you will be able to estimate the number of users and the services they need with greater confidence.

From that point, it becomes possible to begin strategizing the physical layout of your network. In the simplest network, every network element is connected directly to a central server. If this is the case in your network, it is important to test out wireless connectivity in a very early phase of the process. Some buildings are resistant to wireless signals because of their construction or existing wiring.

Wireless signals can also degrade due to local interference from electronic items such as industrial equipment. Where extensive cabling is necessary, map out the building and the anticipated location of each network element to see how cabling can be optimized. Costing a complex network has several steps. You will have to consider not only the cost of each network element, but the cost of cabling and the labor involved. Starting a network requires a significant investment, but it becomes easier to extend your technological capabilities once the network is running.

It is a good idea to standardize the hardware and software configuration of your network terminals to reduce costs. Remember me on this computer. Enter the email address you signed up with and we'll email you a reset link. Need an account?

Whether it is to connect your computers internally as a so called intranet, or to connect various computers to the Internet, a LAN permits you to exchange information between computers without physically going over to the other computer.

All that is strictly necessary to set up a LAN is some sort of a central dispatching device like a router, hub or switch and some network cables. The dispatching device is used to bring the computers together, and the type used depends on the application; a router is used to connect to different subnets, while a hub and a switch connect computers within a subnet, the switch providing a faster connection than the hub.

However, this document will not cover the complete installation of a network; it is very easy to find information about this on the internet. Instead, this document focuses on the production of the network cable. Very few and relatively cheap materials are needed to make a network cable, and the proceedings are simple. In order to connect the connectors to the cable you need a crimping tool.

Look closely at the cable and you should find a print on the jacket. The P for Pair refers to the fact that inside the cable there are 4 pairs of wires. The T for Twisted indicates that each pair of wires is twisted along its longitudinal axis, and inside the cable the 4 pairs are twisted around each other along the longitudinal axis of the cable as well.

This is done so to reduce the effects of electromagnetic interference. Finally, the cable is called Unshielded because covering the inside pairs of wires there is just a plastic jacket, not some special shielding material to shield the cable for interference.

Shielded cables exist as well e. They have 8 canals where the 8 wires of the UTP cable should fit into, and gold coated connecting pins to make the electrical contact. Tools In order to connect the connectors firmly to the cable, a tool called a crimping tool is needed. Its main objective is to press down the contacts of the connector onto the wires permanently this process is called crimping. The crimping tool often includes a wire stripper as well. If no stripping section is present, it will be necessary to have a wire cutter as well.

Figure 3: Crimping tool Steps to make the network cable 1. Cut the wire to the desired length 2. Peel off the plastic at one end of the cable 3. Order the wires 4. Insert the wires into the connector 5. Use the crimping tool to fix the connector on the cable 6. Repeat steps 1 to 4 for the other end 7. Check the connectivity of the cable 1.

Cut the wire to the desired length The cable should not be longer than m. The perfect distance to peel the cable is about half an inch, or 1. If you peel off less, it will be difficult to insert the cable into the connector because the plastic does not fit in.

If you peel off more, the cable will not be reinforced near the connector as there is no plastic, and tends to get damaged rather soon. Figure 4: Using the crimping tool to strip the jacket The crimping tool sometimes has a very convenient plastic edge opposite the cutting blades that stops the cable at the correct distance.

If it is present, use it. It is very important not to damage the wires while cutting away the plastic. Press the cutting blades lightly and tear off the plastic. Next, check that none of the wires has its plastic damaged. If a wire is damaged at this point, you should cut all wires off and start anew.
