Wire maps can be very helpful in troubleshooting cabling problems with UTP cable. A wire map allows the network technician to verify which pins on one end of the cable are connected to which pins on the other end. 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 such as poor connections and split pairs to test. Cables should be numbered to simplify the testing process and to maintain consistency. A cable tester. | Cisco SrsTEMS Lab 4.2.9a Fluke 620 Cable Tester - Wire Map Objective Learn the wire mapping features of the Fluke 620 LAN CableMeter or its equivalent. Learn how to use a cable tester to check for the proper installation of unshielded twisted- pair UTP Category 5 according to TIA EIA-568 cabling standards in an Ethernet network. Background Preparation Wire maps can be very helpful in troubleshooting cabling problems with UTP cable.

A cable tester 1 - 3 CCNA 1 Networking Basics v 3.0 - Lab 4.2.9a Copyright 2003 Cisco Systems Inc. should be available that can test at least continuity cable length and wire map. Work individually or in teams. The following resources will be required CAT 5 straight-wired cables of different colors CAT 5 crossover-wired cable which isT568A on one end and T568B on the other CAT 5 straight-wired cables with open wire connections in the middle or one or more conductors shorted at one end of different colors and different lengths CAT 5 straight-wired cable with a split pair mis-wire Fluke 620 LAN CableMeter or similar to test cable length continuity and wire map Step 1 Turn the rotary switch selector on the tester to the WIRE MAP 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 accept that setting and go to the next one. Continue pressing the UP DOWN arrows and .
