TAILIEUCHUNG - Network+ Certification (Outline) - Chapter 15: Installing a network

Chapter summary: External unshielded twisted pair (UTP) cable installations use prefabricated cables to connect computers directly to hubs; internal cable installations use bulk cable, which you pull through walls, ceilings, or floors; to connect two computers without a hub, you must use a crossover cable connection, which reverses the transmit and receive signals;. | Chapter 15 Installing a Network 1 Chapter Overview A. Pulling Cable B. Making Connections Chapter 15 Lesson 1 Pulling Cable 1. External Installations 2 3 A. Installing network cable is often called pulling cable. 1. The process often involves threading one end of a cable through a wall or ceiling and then pulling the rest of the cable through from the other end. B. An external installation is one in which you use prefabricated UTP cables and run them from each computer to the hub. 1. You do not have to run cables through walls or ceilings attach connectors to bulk cable or purchase additional hardware such as wall plates and patch panels. C. Advantage of external installations 1. External installations are portable you can coil up the cables and take them with you if you have to move the network. D. Disadvantages 1. Cables are often visible. 2. Obstacles between the pieces of network equipment can make running the cable difficult. E. External installation procedure 1. Select the locations for the computers and other network-connected devices such as printers and the hub. a. The hub should be in a central location relative to the computers both to keep your cable lengths to a minimum and to avoid having too many cables running along the same route. 2. Plan the exact route for each cable from the computer or other device to the hub. a. Examine all of the obstacles on each route such as furniture doorways and walls. b. Plan how you will run your cables around or through them. 3. Measure each route from the computer to the hub. a. Take the entire path of the cable into account including vertical runs around doorways paths through walls and other obstacles. b. Leave at least a few extra yards of slack to compensate for unforeseen obstacles and adjustments in the location of the computer or hub. 4. Buy prefabricated cables of the appropriate lengths and possibly colors for each run. 4 5 a. If you are installing UTP cable make sure that all of the cables you purchase are
