5.0 Network+ Certification Cram Notes : Network Troubleshooting
5.2 Explain how to troubleshoot common cable connectivity issues using appropriate tools:
To troubleshoot common cable connectivity issues, the following steps can be taken using appropriate tools:
1. Inspect the cables for physical damage such as cuts, kinks, or fraying. Use a cable tester or a multimeter to verify continuity.
2. Check the cable connections at both ends of the cable. Ensure that they are securely plugged in and that the ports are not damaged.
3. Verify the cable type and speed. Some cables are designed for specific speeds and may not work properly if used in a different application.
4. Use a network scanner or ping utility to test network connectivity. If the connection is down, this will indicate a cable or connection problem.
5. Check for cable interference from other devices. This can cause problems with signal quality and slow down the network.
6. Verify the cable length. Some cables have a maximum length that they can be used for and using them beyond this length can result in signal loss and slow speeds.
7. Test for crosstalk between cables. This can occur when two or more cables run parallel to each other and their signals interfere with each other.
Having the right tools and following these steps can help identify and resolve common cable connectivity issues and keep the network running smoothly.
