Testing network cables with a network cable tester is an essential skill that every professional dealing with computer networking must possess. A network cable tester is a tool that verifies that the network cable is wired correctly and is ready to use. This tool can save you countless hours of troubleshooting and help you diagnose network issues accurately.
The following steps outline how to test network cables using a network cable tester.
Step 1: Gather your tools
Before you begin testing cables, you need to make sure you have all the necessary tools. Apart from the network cable tester, you also need a pair of scissors or cable stripper to strip the outer sheathing of the cable and expose the wires, and a multi-tester to test a voltage.
Step 2: Strip the network cable
Using the scissors or cable stripper, strip off about an inch of the outer sheathing from both ends of the network cable to expose the wires.
Step 3: Separate the twisted pairs
After stripping the outer sheathing, you'll find four pairs of twisted cables inside. Separate the pairs, using either your fingers or a special cable untwist tool.
Step 4: Insert cables into the tester
Insert the cables into the tester. One end of the cable should be inserted into the 'main' jack on the tester while the opposite end goes into the 'remote' jack on the tester.
Step 5: Turn on the tester
Once both ends of the network cable have been plugged in, you can turn on the tester.
Step 6: Interpret the test results
When the tester is displaying results, it will typically indicate if both ends of the cable are correctly wired with specific 'pass' or 'fail' messages depending on the wiring standard. If the cable is wired correctly, the tester will display a 'PASS' message. If the cable is wired incorrectly, the tester will display a 'FAIL' message.
Step 7: Repeat if necessary
If the network cable fails the test, you may need to re-strip the cable and re-test.
Step 8: Test voltage
If the cable continues to fail the test, the next step is to test the voltage. The voltage test helps you to determine if any signal is being transmitted through the cable. To test for voltage, insert the multimeter's probes into the end jacks of the cable tester. If voltage is present, it indicates that the cable has been damaged.
In conclusion, testing network cables with a network cable tester helps you diagnose and rectify issues with networking cables. The steps outlined above are simple and easy to follow, and they can save you a lot of time, money, and frustration.
