Basic cable tests can be very helpful in troubleshooting cabling problems with UTP. The Cabling infrastructure or cable plant in a building is expected to last at least ten years. Cabling-related problems are one of the most common causes of network failure. The quality of cabling components used, the routing and installation of the cable, and quality of the connector terminations will be the main factors in determining how trouble-free the cabling will be. | Cisco SrsTEMS Lab 4.2.9b Fluke 620 Cable Tester - Faults Objective Learn the Cable Test - Pass Fail features of the Fluke 620 LAN CableMeter or an equivalent tester. Learn how to use a cable tester to check for the proper installation of unshielded twisted pair UTP for an Ethernet network. Test different cables to determine some problems that can occur from incorrect cabling installation and termination.

Prior to starting the lab the teacher or lab assistant should have several correctly wired CAT 5 cables to test. The cables should be both straight-through and crossover. There should also be several CAT 5 cables created with problems. Cables should be numbered to simplify the testing process and to maintain consistency. The following resources will be required CAT 5 straight-thru and crossover wired cables of different colors some good and some bad CAT 5 straight-thru and crossover wired cables with open wire connections in the middle or one or more conductors shorted at one end that are different colors and different lengths Cable Tester which is Fluke 620 LAN CableMeter or something similar to test cable length Step 1 Turn the rotary switch selector on the tester to the TEST position. Press the SETUP button to enter the setup mode and observe the LCD screen on the tester. The first option should be CABLE. Press the UP or DOWN arrow buttons until the desired cable type of UTP is selected. Press ENTER to .
