This document provides instructions for setting up a network connection by installing a Network Interface Card (NIC) and crimping cables. It is intended for students learning about computer networks. The document explains how to insert a NIC into an expansion slot and install the proper drivers. It also describes how to crimp both ends of a straight cable by inserting wires into RJ45 connectors according to the 568B standard wiring schematic and then testing the cable for continuity. Completing these tasks will allow students to install a NIC, crimp cables, and set up a basic network.

Learning Module: Computer Networks www.ppk.kpm.my < 20 > CABLE CRIMPING AND TESTING – STRAIGHT CABLE LEARNING OUTCOME: 3.4.2.1 Crimp and test Untwisted Pair (UTP) cable using straight cable technique 3.4.2.2 Exercise care and caution when crimping a cable DURATION: 2 periods REQUIREMENTS: CAT5E cable (3 meters) RJ45 connectors (2 units) Crimp tool Cable stripper Wire cutter LAN cable tester NOTE : A cable is needed to connect a computer to a wired local area network (LAN). There are two types of cables. The first is the “straight cable” which is used to connect computers through a hub. The second type is the “crossed cable” for a direct connection between two computers without using a hub. Connecting these cables is called cable crimping. This module shows how to crimp a straight cable using Untwisted Pair cable and RJ45 connectors.
Learning Module: Computer Networks www.ppk.kpm.my < 21 > ACTIVITIES: 1. Skin off the cable jacket approximately 3cm by using a cable stripper. 2. Untwist each pair, and straighten each wire between fingers. 3. Place the wires in the order of 568B schematic (refer to Table 1 on page 3). Connect all the wires together. 4. At this point, recheck the wiring sequence with the diagram. 5. Optional: Mark a distance of 1.5cm from the end of the cable jacket on the wires. 6. Hold the set and sorted wires together tightly, between the thumb, and the pointer finger. 7. Cut all the wires at 90o angle from the cable at 1.5cm from the end of the cable jacket by using a wire cutter. This is a very critical step. If the wires are not cut straight, they may not make contact with the connector pins. 8. Conductors should be at a 90o angle, and be 1.5cm long, prior to insertion into the connector. 9. Insert the wires into the RJ45 connector with the pins facing up.
Learning Module: Computer Networks www.ppk.kpm.my < 22 > 10.Push moderately to assure that all wires have reached the end of the connector. Be sure that the cable jacket goes into the back of the connector at 0.3cm. 11.Place the connector into a crimp tool, and squeeze hard so that the handle reaches its full swing. 12.Repeat step 1 to 11 for the other end of the cable. 13.Use a cable tester to test for proper continuity.

  • 22. Learning Module: Computer Networks www.ppk.kpm.my < 20 > CABLE CRIMPING AND TESTING – STRAIGHT CABLE LEARNING OUTCOME: 3.4.2.1 Crimp and test Untwisted Pair (UTP) cable using straight cable technique 3.4.2.2 Exercise care and caution when crimping a cable DURATION: 2 periods REQUIREMENTS: CAT5E cable (3 meters) RJ45 connectors (2 units) Crimp tool Cable stripper Wire cutter LAN cable tester NOTE : A cable is needed to connect a computer to a wired local area network (LAN). There are two types of cables. The first is the “straight cable” which is used to connect computers through a hub. The second type is the “crossed cable” for a direct connection between two computers without using a hub. Connecting these cables is called cable crimping. This module shows how to crimp a straight cable using Untwisted Pair cable and RJ45 connectors.
  • 23. Learning Module: Computer Networks www.ppk.kpm.my < 21 > ACTIVITIES: 1. Skin off the cable jacket approximately 3cm by using a cable stripper. 2. Untwist each pair, and straighten each wire between fingers. 3. Place the wires in the order of 568B schematic (refer to Table 1 on page 3). Connect all the wires together. 4. At this point, recheck the wiring sequence with the diagram. 5. Optional: Mark a distance of 1.5cm from the end of the cable jacket on the wires. 6. Hold the set and sorted wires together tightly, between the thumb, and the pointer finger. 7. Cut all the wires at 90o angle from the cable at 1.5cm from the end of the cable jacket by using a wire cutter. This is a very critical step. If the wires are not cut straight, they may not make contact with the connector pins. 8. Conductors should be at a 90o angle, and be 1.5cm long, prior to insertion into the connector. 9. Insert the wires into the RJ45 connector with the pins facing up.
  • 24. Learning Module: Computer Networks www.ppk.kpm.my < 22 > 10.Push moderately to assure that all wires have reached the end of the connector. Be sure that the cable jacket goes into the back of the connector at 0.3cm. 11.Place the connector into a crimp tool, and squeeze hard so that the handle reaches its full swing. 12.Repeat step 1 to 11 for the other end of the cable. 13.Use a cable tester to test for proper continuity.
