A cable1-3CCNA 1: Networking Basics v 3.1 - Lab 4.2.9aCopyright 2003, Cisco Systems, Inc.tester should be available that can test at least continuity, cable length, and wire map. Workindividually or in teams. The following resources will be required:•Category 5 straight-wired cables of different colors•Category 5 crossover-wired cable, which isT568A on one end and T568B on the other•Category 5 straight-wired cables with open wire connections in the middle or one or moreconductors shorted at one end of different colors and different lengths•Category 5 straight-wired cable with a split pair mis-wire•Fluke 620 LAN CableMeter or similar to test cable length, continuity, and wire mapStep 1Turn the rotary switch selector on the tester to the WIRE MAP position.
Press the SETUP button toenter 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 ENTERto accept that setting and go to the next one. Continue pressing the UP/DOWN arrows and pressingENTER until the tester is set to the following cabling characteristics:Tester OptionDesired Setting – UTPCABLE:UTPWIRING:10BASE-T or EIA/TIA 4PRCATEGORY:CATEGORY 5WIRE SIZEAWG 24CAL to CABLE?NOBEEPING:ON or OFFLCD CONTRASTFrom 1 through 10 (brightest)Step 2Once the student has completed setting up the meter, press the "SETUP" button to exit setup mode.For each cable to be tested use the following procedure.
Place the near end of the cable into the RJ45 jack labeled UTP/FTP on the tester. Place the RJ-45-RJ-45 female coupler on the far end of thecable, and then insert the cable Identifier into the other side of the coupler. The coupler and thecable identifier are accessories that come with the Fluke 620 LAN CableMeter.Step 3Using the tester Wire Map function and a Cable ID Unit, the wiring of both the near and far end of thecable can be determined. The top set of numbers displayed on the LCD screen is the near end, and2-3CCNA 1: Networking Basics v 3.1 - Lab 4.2.9aCopyright 2003, Cisco Systems, Inc.the bottom set is the far end.
Perform a Wire Map test on each of the cables provided. Then fill in thefollowing table based on the result for each Category 5 cable tested. For each cable, write down thenumber and color, whether the cable is straight-through or crossover, the tester screen test results,and what the problem is.CableNo.CableColorHow cable is wired(straight-through orcrossover)Test Displayed Test Results(Note: Refer to the Flukemanual for detailed descriptionof test results for wire map.)1Top:Bot:2Top:Bot:3Top:Bot:4Top:Bot:5Top:Bot:3-3CCNA 1: Networking Basics v 3.1 - Lab 4.2.9aProblem DescriptionCopyright 2003, Cisco Systems, Inc.Lab 4.2.9b Fluke 620 Cable Tester – FaultsObjective•Learn the Cable Test - Pass / Fail features of the Fluke 620 LAN CableMeter or an equivalenttester.•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 cablinginstallation and termination.Background / PreparationBasic cable tests can be very helpful in troubleshooting cabling problems with UTP.
The Cablinginfrastructure or cable plant in a building is expected to last at least ten years. Cabling-relatedproblems are one of the most common causes of network failure. The quality of cabling componentsused, the routing and installation of the cable, and quality of the connector terminations will be themain factors in determining how trouble-free the cabling will be.1-3CCNA 1: Networking Basics v 3.1 - Lab 4.2.9bCopyright 2003, Cisco Systems, Inc.Prior to starting the lab, the teacher or lab assistant should have several correctly wired Category 5cables to test.
The cables should be both straight-through and crossover. There should also beseveral Category 5 cables created with problems. Cables should be numbered to simplify the testingprocess and to maintain consistency. The following resources will be required:•Category 5 straight-through and crossover wired cables of different colors, some good and somebad•Category 5 straight-through and crossover wired cables with open wire connections in the middleor 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 lengthStep 1Turn the rotary switch selector on the tester to the TEST position.
Press the SETUP button to enterthe setup mode and observe the LCD screen on the tester. The first option should be CABLE. Pressthe UP or DOWN arrow buttons until the desired cable type of UTP is selected. Press ENTER toaccept that setting and go to the next one. Continue pressing the UP/DOWN arrows and pressingENTER until the tester is set to options in the chart below.

Perform a basic cable test on each of the cables provided. Then fill in the following table2-3CCNA 1: Networking Basics v 3.1 - Lab 4.2.9bCopyright 2003, Cisco Systems, Inc.based on the result for each Category 5 cable tested.
