Lab 5.3.1 Basic Cable TesterEstimated time: 30 min.Objectives:Use a cable tester to verify that a straight-thru or crossover cable is good or bad Background:UTP Ethernet Cabling: Cabling is one of the most critical areas of network design and implementation. The cabling is expected to last from 10 to 15 years. The quality of cable and connections is a major factor in reducing network problems and time spent troubleshooting. Unshielded Twisted Pair (UTP) copper cable is the most common in use today's Ethernet networks. There are various Categories (CAT 3, CAT 5, CAT 5e etc.) but all of them contain 8 wires or conductors and use RJ45 connectors. A UTP patch cable in a network is usually wired as a straight-thru or crossover. In order to follow proper specifications, all 8 conductors must be used even though with most earlier versions of Ethernet, not all 8 conductors were used. You will create these cables in the future labs. In this lab you will work with several cables that have already been made and will test them for basic continuity (breaks in wires) and shorts (2 or more wires touching) using a basic cable tester. (refer to the lab on resistance measurements).Basic Cable Testers: There are a number of very simple and inexpensive basic cable testers available (less than $100). They usually consist of one or two small boxes with RJ45 jacks in them to plug the cables to be tested into. Many of these are designed specifically to test only Ethernet UTP type of cable. The testers will have more than one jack to allow for testing of straight thru or crossover cable. Both ends of the cable are plugged in to the proper jacks and the tester will test all 8 wires and indicate whether the cable is good or bad. If any of the eight wires has a break or is shorted to any of the other wires, the cable is bad. The simple testers may just have a single light to indicate this; others may have eight lights to tell you which wire is bad. These testers have internal batteries and are doing continuity checks on the wires.Advanced Cable Testers: Advanced cable testers, such as the Fluke 620 LAN CableMeter, are sophisticated cable testers which have basic cable testing functions and much more. You will use an advanced cable tester in future labs to do wire maps etc. If an inexpensive basic cable tester is unavailable, the Fluke (or equivalent) is more than adequate. Advanced cable tests can cost from hundreds to thousands of dollars.Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have several basic cable testers available (one for each team of students) or several Fluke Cable meters and various lengths of wire with induced problems. Work in teams of two. The following resources will be required:Basic cable tester Advanced cable tester (Fluke 620 or equivalent) 2 lengths of good CAT 5 cable (one crossover and one straight-thru, use different colors or labels) 2 lengths of bad CAT 5 cable (one with a break and one with a short, use different colors or labels) If you are using a basic cable tester, refer to the instructions from the manufacturer and insert the ends of the cable to be tested into the jacks accordingly. If you are using the Fluke 620, use the following instructions to test the four cables. Insert the RJ45 from one end of the cable into the UTP/FTP jack on the tester and turn the dial to test. All conductors will be tested to verify they are not broken or shorted. (Note: this test does not verify that the pins are connected correctly from one end to the other)Notes:Step 1 1st Cable test - Insert the cable into the RJ45 jack(s) of the cable tester.What is the color or cable number of this cable? _______________________________________ What category type of cable is it (CAT 3, CAT 5 etc.)? __________________________________ How is the cable wired (straight-thru or crossover)? _____________________________________ How long is the cable? ____________________________________________________________ Did cable test out ok? ____________________________________________________________ Step 2 2nd Cable test - Insert the cable into the RJ45 jack(s) of the cable tester.What is the color or cable number of this cable? _______________________________ What Category type of cable is it (CAT 3, CAT 5 etc)? __________________________ How is the cable wired (straight-thru or crossover)? _____________________________ How long is the cable? ___________________________________________________ Did cable test out OK ? __________________________________________________ Step 3 3rd Cable test - Insert the cable into the RJ45 jack(s) of the cable tester.What is the color or cable number of this cable? _______________________________ What Category type of cable is it (CAT 3, CAT 5 etc)? __________________________ How is the cable wired (straight-thru or crossover)? _____________________________ How long is the cable? ___________________________________________________ Did cable test out OK ? __________________________________________________ Step 4 4th Cable test - Insert the cable into the RJ45 jack(s) of the cable tester.What is the color or cable number of this cable? _______________________________ What Category type of cable is it (CAT 3, CAT 5 etc)? __________________________ How is the cable wired (straight-thru or crossover)? _____________________________ How long is the cable? ___________________________________________________ Did cable test out OK ? __________________________________________________ Lab 5.3.1 BASIC CABLE TESTER - ANSWERSAnswers will vary depending on the cables being tested and the problems they have. Lab 5.3.2 Straight-Thru CableEstimated time: 30 min.Objectives:Build a straight-through Ethernet patch cable to T568-B (OR T568-A) standards for connection from workstation to hub/switch or patch panel to hub/switch. Background:In this lab you will learn how to build a Category 5 (CAT 5) Unshielded Twisted Pair (UTP) Ethernet network patch cable (or patch cord) and test it for good connections (continuity) and correct pinouts (correct color of wire on the right pin). This will be a 4-pair (8-wires) "straight through" cable which means that the color of wire on pin 1 on one end of the cable will be the same as pin 1 on the other end. Pin 2 will be the same as pin 2 and so on. It will be wired to TIA/EIA-568-B or A standards for 10Base-T Ethernet which determines what color wire is on each pin. T568-B (also called AT&T specification) is more common but many installations are also wired to T568-A (also called ISDN).This patch cable will conform to the structured cabling standards and is considered to be part of the "horizontal" cabling which is limited to 99 meters total between workstation and hub or switch. It can be used in a workstation area to connect the workstation NIC to the wall plate data jack or it can be used in the wiring closet to connect the patch panel (horizontal cross connect) to an Ethernet hub or switch. Patch cables are wired straight thru since the cable from the workstation to the hub or switch is normally crossed over automatically at the switch or the hub. Note that the ports on most hubs have an X next to them. This means the send and receive pairs will be crossed when the cabling reaches the switch. The pinouts will be T568-B and all 8 conductors (wires) should be terminated with RJ45 modular connectors (only 4 of the 8 wires are used for 10/100base-T Ethernet, all 8 are used for 1000Base-T Ethernet).Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair (UTP) cable, RJ45 (8-pin) connectors, an RJ45 crimping tool and an Ethernet / RJ45 continuity tester available. Work individually or in teams. The following resources will be required:Two to three foot length of Cat 5 cabling (one per person or one per team) Four RJ45 connectors (two extra for spares) RJ45 Crimping Tools to attach the RJ45 connectors to the cable ends Ethernet cabling continuity tester which can test straight through or crossover type cables (T568-A or T568-B). Wire cutters Step 1 - Cabling Information.Explanation: Instructions are provided here for building a T568-A or T568-B cable. Either can be used as long as all connections (pinouts) from the workstation to the wiring closet and terminating electronics (hubs or switches) are consistent. If cables are to be built for an existing network it is important to keep the same standard as already exists (either T568-A or B). A patch cable that is wired "straight through" will have the same color of wire on the same pin (1 8) at both ends. A straight through patch cable (T568-A or B) can be used to connect a PC workstation to a wall plate in a work area or it can be used to connect from a patch panel in a wiring closet to a hub or a switch. A PC can also be connected directly to a port on a hub or switch with this cable. If a cable will be used to connect from an "Uplink" port on one hub to a "crossover" front port on another hub then a straight through cable should be usedStep 2 - Create a T568-B straight-thru patch panel cable.Task: Use the following tables and diagrams and steps to create a T568-B patch panel cable. Explanation: Both cable ends should be wired the same when looking at the conductors. Only four wires are used with 10Base-T or 100Base-TX Ethernet:T568-B CablingPin# Pair# Function Wire Color Used with 10/100 Base-T Ethernet? Used with 100 Base-T4 and 1000 Base-T Ethernet? 1 2 Transmit White/Orange Yes Yes 2 2 Receive Orange/White Yes Yes 3 3 Transmit White/Green Yes Yes 4 1 Not used Blue/White No Yes 5 1 Not used White/Blue No Yes 6 3 Receive Green/White Yes Yes 7 4 Not used White/Brown No Yes 8 4 Not used Brown/White No Yes Determine the distance between devices, or device and plug, then add at least 12" to it. The maximum length for this cord is 3 m; standard lengths are 6' and 10'.Cut a piece of stranded Cat 5 unshielded twisted-pair cable to determined length. You will use stranded cable for patch cables because it is more durable when bent repeatedly. Solid wire is fine for cable runs that are punched down into jacks.Strip 2" of jacket off of one end of the cable.Hold the 4 pairs of twisted cables tightly where jacket was cut away, then reorganize the cable pairs into the order of the 568-B wiring standard. Take care to maintain the twists since this provides noise cancellation. (orange pair, green pair, blue pair, brown pair).Hold the jacket and cable in one hand, untwist a short length of the green and blue pairs, and reorder them to reflect the 568-B wiring color scheme. Untwist and order the rest of the wire pairs according to the color scheme.Flatten, straighten, and line up the wires, then trim them in a straight line to within 1/2" - 3/4" from the edge of the jacket. Be sure not to let go of the jacket and the wires, which are now in order! You should minimize the length of untwisted wires because overly-long sections that are near connectors are a primary source of electrical noise.Place an RJ-45 plug on the end of the cable, with the prong on the underside and the orange pair at the top of the connector.Gently push the plug onto wires until you can see the copper ends of the wires through the end of the plug. Make sure the end of the jacket is inside the plug and all wires are in the correct order. If the jacket is not inside the plug, it will not be properly strain relieved and will eventually cause problems. If everything is correct, crimp the plug hard enough to force the contacts through the insulation on the wires, thus completing the conducting path.Repeat steps 3-8 to terminate the other end of the cable, using the same scheme to finish the straight through cable.Test the finished cable and have the instructor check it. How can you tell if your cable is functioning properly? __________________________________________________________ Lab 5.3.2 STRAIGHT-THRU CABLE - ANSWERSAnswers: There are several methods that can be used to check the cable. Have the instructor check your cable and verify it using one or more of these tests: Visual Test: Inspect the cable ends visually. Hold the RJ45 connectors side by side and the same color wire should be on the same pin. This is not a conclusive test but is a good start. Cable Test: You can test the cable with a cable tester to verify the wires have continuity (no breaks) and are not shorted. Functional Test: You can connect your cable from a workstation to a hub and verify that you can see other workstations. This is the ultimate test but requires more setup and configuration time. Lab 5.3.3 Rollover CableEstimated time: 30 min.Objectives:Build a rollover cable for connection from a workstation to the console port on a router or switch Background:In this lab you learn how to build a Category 5 (CAT 5) Unshielded Twisted Pair (UTP) console rollover cable and test it for good connections (continuity) and correct pinouts (correct wire on the right pin). This will be a 4-pair (8-wires) "rollover" cable.This cable should be approximately 10 feet in length but can be as long as 25 feet. It can be used to connect a workstation or dumb terminal to the console port on the back of a router or Ethernet switch in order to be able to configure the router or switch. This cable uses an asynchronous serial interface to the router or switch (8 data bits, No parity and 2 Stop bits). Both ends of the cable you build will have RJ45 connectors on them. One end plugs directly into the RJ45 console management port on the back of the router or switch and the other end plugs into an RJ45-to-DB9 terminal adapter. This adapter converts the RJ 45 to a 9-pin female D connector that plugs into the DB9 serial port male adapter on the back of a PC running terminal emulation software such as HyperTerminal. A DB25 terminal adapter is also available to connect with a dumb terminal which has a 25 pin connector.A rollover cable uses 8 pins but is different from the straight-through cable or crossover cable that you will build in other labs. With a rollover cable, pin 1 on one end connects to pin 8 on the other end. Pin 2 connects to pin 7, pin 3 connects to pin 6 and so on. This is why it is referred to as a rollover since the pins on one end are all reversed on the other end as though one end of the cable was just rotated or rolled over.A flat black rollover cable comes with each new router or switch along with the terminal adapters for both DB9 and DB25 connections to terminals or PC serial ports. It is approximately 8 feet long. This lab will enable you to build another cable if the one that comes with the router or switch is damaged or lost. It will also allow you to connect to routers or switches from workstations that are greater than 8 feet away by building your own longer cables.Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair (UTP) cable, RJ45 (8-pin) connectors, an RJ45 crimping tool and a continuity tester available. Work individually or in teams. The following resources will be required:10 to 20 foot length of Cat 5 cabling (one per person or one per team) Four RJ45 connectors (two extra for spares) RJ45 Crimping Tools to attach the RJ45 connectors to the cable end An RJ45 to DB9 female terminal adapter (available from Cisco) Cabling continuity tester Wire cutters Step 1. Review Cable Connections and Pin LocationsUse the following table as a reference to answer the following questions and help you create a rollover console cable.Questions:Which signal on the Router port (column 1 of the table) will be used to transmit data to the PC when the PC is first connected and HyperTerminal is started (this is what displays the router prompt on the workstation.)? __________________________________________________________ Which pin is this connected to on the router end of the RJ45 cable? __________________ Which pin is this connected to on the other end of the RJ45 cable? ___________________ Which pin is this connected to in the DB9 connector? ______________________________ Which Console device signal does this connect to? ________________________________ What would happen if pin 3 on the left cable end were attached to pin 3 as with a straight-thru cable?______________________________________________________________________________________________________________________________________________ Rollover Console Cable TableFor connecting from a router or switch console port to a PC workstation running HyperTerminal terminal emulation software.

Use the following steps to build the rollover console cable.Determine the distance between devices, then add at least 12" to it. Make your cable about 10 feet unless you are connecting to router or switch from a greater distance. The maximum length for this cable is about 8m (appx 25 feet).Strip 2" of jacket off of one end of the cable.Hold the 4 pairs of twisted cables tightly where jacket was cut away, then reorganize the cable pairs and wires into the order of the 568-B wiring standard. You can order them in any sequence but use the 568-B sequence to become more familiar with it.Flatten, straighten, and line up the wires, then trim them in a straight line to within 1/2" - 3/4" from the edge of the jacket. Be sure not to let go of the jacket and the wires, which are now in order!Place an RJ-45 plug on the end of the cable, with the prong on the underside and the orange pair at the top of the connector.Gently push the plug onto wires until you can see the copper ends of the wires through the end of the plug. Make sure the end of the jacket is inside the plug and all wires are in the correct order. If the jacket is not inside the plug, it will not be properly strain relieved and will eventually cause problems. If everything is correct, crimp the plug hard enough to force the contacts through the insulation on the wires, thus completing the conducting path.Repeat steps 2-6 to terminate the other end of the cable, but reversing every pair of wires as indicated in the table above. (Pin 1 to Pin 8, pin 2 to pin 7, pin 3 to pin 6 and so on.Test the finished cable and have the instructor check it.

Which Console device signal does this connect to? RxD6. What would happen if Pin 3 on the left cable end were attached to pin 3 as with a straight-thru cable? (Transmit Data (TxD) from the router would be connected to the Transmit Data (TxD) on the workstation and they would never communicate.Step 2Use the following steps to build the rollover console cable.8. Test the finished cable and have the instructor check it. How can you tell if your cable is functioning properly? There are several methods that can be used to check the cable.Visual Test: The cable ends can be visually inspected and should be wired exactly opposite when looking at the conductors and holding the RJ45 connectors side by side with the clip facing down. If you hold the RJ45 connectors end to end with the clip facing down the wire colors should match. Pinouts are listed in the table.Cable Test: You can test the cable with a cable tester to verify the wires have continuity (no breaks) and are not shorted.Functional Test: You can connect your rollover cable to the RJ45-to-DB9 terminal adapter and connect a workstation to the router to verify that you can see the router console prompts. This is the ultimate test and also requires that HyperTerminal be set up properly on the Workstation (8 data bits, No parity, 2 Stop bits) Lab 5.3.4 Crossover CableEstimated time: 30 min.Objectives:Build a crossover Ethernet patch cable to T568-B (or T-568-A) standards for connection from workstation to workstation or from switch to switch. Background:In this lab you will learn how to build a Category 5 (CAT 5) Unshielded Twisted Pair (UTP) Ethernet crossover network cable and test it for good connections (continuity) and correct pinouts (correct color of wire on the right pin). This will be a 4-pair (8-wires) "crossover" cable which means that pairs 2 and 3 on one end of the cable will be reversed on the other end. It will be wired to TIA/EIA-568-B and A standards for 10Base-T Ethernet which determines what color wire is on each pin. The pinouts will be T568-A on one end and T568-B on the other end. All 8 conductors (wires) should be terminated with RJ45 modular connectors.This patch cable will conform to the structured cabling standards and, if it is used between hubs or switches, is considered to be part of the "vertical" cabling also know as backbone cable. A crossover cable can be used as a backbone cable to connect two or more hubs or switches in a LAN or to connect 2 isolated workstations to create a mini-LAN. This will allow you to connect two workstations together or a server and a workstation without the need for a hub between them. This can be very helpful for training and testing. If you want to connect more than two workstations you will need a hub or a switch.Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair (UTP) cable, RJ45 (8-pin) connectors, an RJ45 crimping tool and an Ethernet / RJ45 continuity tester available. Work individually or in teams. The following resources will be required:Two to three foot length of Cat 5 cabling (one per person or one per team) Four RJ45 connectors (two extra for spares) RJ45 Crimping Tools to attach the RJ45 connectors to the cable ends Ethernet cabling continuity tester which can test crossover type cables (T568-A to T568-B). Wire cutters Step 1 Create a crossover patch panel cable.Use the following tables and diagrams and steps to create a crossover cable. One end of the cable should be wired to the T568-A standard and the other end to the T568-B standard. This crosses the transmit and receive pairs (2 and 3) to allow communication to take place.

Lab 5.3.5 Cable Tester - Wire MapEstimated time: 45 min.Objectives:Demonstrate skill with a cable tester more advanced than a simple continuity/pin-out tester Use the wire mapping features of the tester to check for opens and shorts with UTP cable Perform wire mapping on cables, detecting faults that are not detectable with simple continuity measuring devices such as crossed and split pairs Background:In this lab, you will learn the Wire Mapping features of the Fluke 620 LAN CableMeter (or its equivalent). Wire maps can be very helpful in troubleshooting cabling problems with UTP cable. Wire maps are not used with coaxial cable since there is only one wired and no map is needed. 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. With an understanding of the proper wiring connections, you can determine when a cable is wired improperly, depending on its intended use. You will learn how to use a cable tester to check for the proper installation of Unshielded Twisted Pair (UTP) Category 5 (CAT 5) according to TIA/EIA-568 cabling standards in an Ethernet network. You will test different cables using all four pairs to determine some problems that can occur from incorrect cabling installation and termination.The Cabling infrastructure (or cable plant) in a building is expected to last at least 10 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.Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have several correctly wired CAT 5 cables (both straight thru and crossover) to test. 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 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 (T568A 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.

Wire maps can be very helpful in troubleshooting cabling problems with UTP cable. Wire maps are not used with coaxial cable since there is only one wired and no map is needed. 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. With an understanding of the proper wiring connections, you can determine when a cable is wired improperly, depending on its intended use. You will learn how to use a cable tester to check for the proper installation of Unshielded Twisted Pair (UTP) Category 5 (CAT 5) according to TIA/EIA-568 cabling standards in an Ethernet network. You will test different cables using all four pairs to determine some problems that can occur from incorrect cabling installation and termination.The Cabling infrastructure (or cable plant) in a building is expected to last at least 10 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.Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have several correctly wired CAT 5 cables (both straight thru and crossover) to test. 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 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 (T568A 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.
