The student will use some of the key capabilities of the Fluke LinkRunner suchas cable mapping and NIC Test.As networks run faster and become more complex, infrastructure cabling and devices must operateto precise levels in a tighter performance window. As a result, nearly 80% of network problems stemfrom simple wiring and connection problems.
The following resources will be required:1-5•Ethernet straight-through patch cables, which are good and bad•Ethernet crossover cables•Ethernet cable from wall plate RJ-45 jack through a patch panel•Hub and/or switch•Computer with NICCCNA 1: Networking Basics v 3.1 - Lab 4.2.9eCopyright 2003, Cisco Systems, Inc.The following URLs provide information on the Fluke LinkRunner.

What is the length of the cable being tested? ______________________________________Step 5 Test length and wire map for good and bad patch cablesThe Cable Test function helps to determine whether the cable length is within specification, if it is astraight or crossover, and whether it has any faults. These tests work for both structured and patchcables. This will test cable integrity for excessive length, opens, shorts, crossed wires, and splitpairs.a. Turn on the LinkRunner by pressing the small button in the lower right corner.b.
Use a good straight through patch cable. Plug one end of the cable into the RJ-45 LAN port onthe LinkRunner and the other end into the LinkRunner RJ-45 MAP port. The diagram belowshows the result of testing a good straight through cable. What is the length of the cable?______________Explain how to tell if this is a straight through or crossover cable.
______________c.Use a good crossover cable. Plug one end of the cable into the RJ-45 LAN port on theLinkRunner and the other end into the LinkRunner RJ-45 MAP port.

Turn on the LinkRunner by pressing the small button in the lower right corner.b. Use a good workstation patch cable drop to a wall plate, which is connected to a patch panel atthe other end but not to a hub or switch. Plug the cable into the RJ-45 LAN port on theLinkRunner. Plug the wire map adapter into the associated patch panel port on the opposite end.This will test the cable run from the patch cable in the work area through all horizontal cabling tothe patch panel in the wiring closet.c.What is the length of the cable? ______________________d. Does the cable test OK? ___________________________e.
If not, indicate problems encountered.__________________________________________________________________________Step 7 Use Link Pulse to test the connection to a hub/switch and identify the cable locationLink Pulse blinks the hub or switch port link light while simultaneously sending a tone on the wire toaid in cable location. Use the optional Microprobe Tone Receiver to pick up a tone and audibly locatecables. The optional Cable ID kit can be used to identify unmarked segments.a. Obtain a good patch cable of any length. Plug one end directly into an active regular hub orswitch port. Plug the other end into the LinkRunner LAN port.__________________________________________________________________________b.
Press the left SoftKey (musical note and hub symbol). What does this cause the link light on thehub or switch port to do?__________________________________________________________________________c.What does this test do and how could it be useful in locating or identifying where cablesterminate?__________________________________________________________________________4-5CCNA 1: Networking Basics v 3.1 - Lab 4.2.9eCopyright 2003, Cisco Systems, Inc.Step 8 Test PC NIC functionalitya.
Turn on the LinkRunner by pressing the small button in the lower right corner.b. Plug one end of a patch cable into the RJ-45 LAN port on the LinkRunner and the other end intothe PC NIC. If the PC NIC link light comes on, then the NIC is good. Did the NIC test OK?________________________________Step 9 Disconnect the equipment and store the cabling and devices5-5CCNA 1: Networking Basics v 3.1 - Lab 4.2.9eCopyright 2003, Cisco Systems, Inc.Lab 5.1.5 RJ-45 Jack Punch DownObjective•Learn the correct process for terminating or punching down an RJ-45 jack•Learn the correct procedure for installing the jack in a wall plateBackground / PreparationIn this lab, the student will learn to wire an RJ-45 data jack for installation in a wall plate using apunch-down tool.
These skills are useful when it is necessary to install a small amount of cabling inan office or residence. A punch tool is a device that uses spring-loaded action to push wires betweenmetal pins, while at the same time skinning the sheath away from the wire. This ensures that the wiremakes a good electrical connection with the pins inside the jack. The punch tool also cuts off anyextra wire.Category 5 or Category 5e cabling and Category 5 or 5e rated T568B jacks will be used. A Category5/5e straight-through patch cable with an RJ-45 connector will normally plug into this data jack oroutlet to connect a PC in a work area to the network. It is important to use Category 5 or 5e ratedjacks and patch panels with Category 5 or 5e cabling in order to support Fast Ethernet (100 Mbps)and Gigabit Ethernet (1000 Mbps).
The process of punching down wires into a data jack in an officearea is the same as punching them down in a patch panel in a wiring closet. The following resourcesare required:•60 - 90 cm (2 - 3 feet) length of Category 5/5e cabling, which can be one per person or one perteam•Two Category 5/5e RJ-45 data jacks (one extra for spare) – If RJ-45 data jacks are installed onboth ends of the cable, the installation can be tested by inserting cable with RJ-45 connectorsand a simple cable continuity tester.•Category 5/5e wall plate•110 type punch-down tool•Wire cuttersUse the following procedure and diagram to punch down the wires into the RJ-45 jack and install thejack into the wall plate:Step 1Remove the jacket 2.54 cm (1 inch) from the end of the cable.Step 2Position wires in the proper channels on the jack maintaining the twists as closely as possible.
