Equipment
• Two 0.6 to 0.9m (2 to 3 ft.) lengths of cable, Category 5 or 5e
• A minimum of four RJ-45 connectors (more may be needed if mis-wiring occurs)
• An RJ-45 crimping tool
• Two computers with Windows 7, Windows Vista, or Windows XP.
• Wire cutters • Wire stripper
Steps
1. Cut the cable to about a 3 foot length.
2. Remove the outer plastic covering using a wire stripper. Make sure to cut the right length by using the connector for reference.
3. Separate the wires apart from each other making sure to only untwist the pairs as far as necessary.
4. Arrange the wires according to the diagram given.
5. Insert the wires into the connector making sure the wires stay in the intended order.
6. Use the crimp tool to secure the wires in the connector. Once crimped, visually inspect connector and use pull test to check crimp.
7. Repeat steps 2-6 on the opposite end of the cable.
8. Insert ends into the cable tester to check cable.
