Curs Test informatica cap.9 RJ45 Jack Outlet Install

Lab 9.2.12 RJ45 Jack Outlet InstallEstimated time: 45 min.Objectives:Learn the correct process for terminating (punching-down) a RJ-45 jack Learn the correct procedure for installing the jack in a wall plate Background:In this lab, you will learn to wire an RJ45 data jack for installation in a wall plate using a punch-down tool. These skills are useful when you must install a small amount of cabling in an office or residence. A punch tool is a device that uses spring-loaded action to push wires between metal pins, while at the same time, skinning the sheath away from the wire. This ensures that the wire makes a good electrical connection with the pins inside the jack. The punch tool also cuts off any extra wire.You will work with CAT 5 cabling and CAT 5 rated T568-B jacks. A CAT 5 straight-wired patch cable with an RJ45 connector will normally plug into this data jack (or outlet) to connect a PC in a work area to the network. It is important that you use CAT 5 rated jacks and patch panels with CAT 5 cabling in order to support higher speed versions of Ethernet such as Fast Ethernet which is 100Mbps. The process of punching down wires into a data jack in an office area is the same as punching them down in a patch panel in a wiring closet such as a Main Distribution Facility (MDF) or Intermediate Distribution Facility (IDF).Tools / Preparation:Prior to starting the lab, the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair (UTP) cable, several RJ45 data jacks, a 110 Punch down 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) Two CAT 5 RJ45 data jacks (one extra for spare) If RJ45 data jacks are installed on both ends of the cable, the installation can be tested by inserting cable with RJ 45 connectors and a simple cable continuity tester CAT 5 Wall Plate 110 type punch down tool Wire cutters WorksheetUse the following procedure and diagram below to punch down the wires into the RJ45 jack and install the jack into the wall plate:Step 1. Remove jacket 1" from the end of the cable.Step 2. Position wires in the proper channels on the jack, according to the color chart below.Step 3. Use the 110 punch-down tool to push conductors into the channels. Make sure that you position the cut side of the punch-down tool so that it faces the outside of the jack, or you will cut the wire you are trying to punch-down. (Note: If you tilt the handle of the punch tool a little to the outside, it will cut better). If any wire remains attached, after you have used the punch tool, simply twist the ends gently to remove them, then, place the clips on the jack, and tighten them. NOTE: Make sure that no more than .5" of untwisted wire is between the end of the cable jacket and the channels on the jack.Step 4. Snap the jack into its faceplate by pushing it in from the back side. Make sure, when you do this, that the jack is right-side up (clip faces down when wall plate is mounted).Step 5. Use the screws to attach the faceplate to either the box, or to the bracket. If you have surface-mounted the box, keep in mind that it may hold a 1'-2' of excess cable. Then you need to either slide the cable through its tie-wraps, or pull back the raceway that covers it, in order to push the rest of the excess cable back into the wall. If you have flush-mounted the jack, all you need to do is push the excess cable back into the wall.Category 5 568-B jack wiring color schemeHold the jack with the 8-pin jack receptacle (the part the RJ45 connector goes into) facing up or away from you while looking at the wire channels or slots. There should be four wire channels on each side.8-pin receptacle White Green White Blue Green Blue White Brown White Orange Brown Orange LAB 9.2.12.1 RJ45 JACK INSTALL - ANSWERSUse the following procedure and diagram below to punch down the wires into the RJ45 jack and install the jack into the wall plate:Step 1.

You may want to point out that this same procedure is used to punch down into a patch panel, another necessary skill for cable installation. Lab 9.5.1 Demo Cable Installation Estimated time: 30 min.Objectives:To learn three crucial cable installation skills: stringing, running, and mounting Cat 5 Cable Background:How you do this lab depends on your instructor's choice of project. You may simply string, run, and mount some cable temporarily for practice. Or you may be actually wiring some or part of your lab. Or you may be doing your structured cabling project, installing networks in some other part of the school or some small business. Regardless of where you are doing your project, you should follow the same professional standards. These were described in Learning Objective 9.4. Assume that one end of your cable run will terminate, via punchdown, in a RJ-45 jack. Assume the other end of your cable run will terminate, via punchdown, in an RJ-45 Patch panel. Assume you will to put the cable in raceway, in ceilings, around obstructions various conditions you will likely encounter.Tools / Preparation:Basic materials include spools of Cat 5 cable, wire cutter/strippers, punchdown tools, raceway, various mounting consumables like cable ties, cable label, surface mounts, RJ-45 jacks and outlets, rack mounted patch panels, a mock wall, etc., fish tape and telepole, safety goggles, a ladder. The actual complete list and quantity of materials depends heavily on your actual project. Use the Cost Calculator, available on the Community Server, for a complete lab list and estimated quantities and costs. In other words, actual tools and preparation depend heavily on local conditions and resources. The following resources will be required:Equipment / ToolsWire cutter / strippers Fish tape Telepole Safety goggles Ladder Punchdown tools ConsumablesCat 5 cable Raceway Cable ties, Cable label Surface mounts RJ-45 jacks and outlets Rack mounted patch panels Mock wall (2x4 with drywall) WorksheetBefore starting the lab, you and your group should plan your cable run. Walk from where the RJ-45 jack and outlet will be to where the patch panel will be. Look for hazards, obstructions, light fixtures, difficult to reach places, places where cable and raceway will be difficult to mount. Prepare a plan, which includes a diagram of your entire run, the total lengths of cable and raceway you will need, and how you plan to actually install the cable (for example, will you need a ladder to reach a high point in the room?). Once your plan is approved by your instructor, then follow the procedures your instructor has described for you and your team to demonstrate the following procedures/techniques:Fish cable from above. Fish cable from below. String cable through a dropped ceiling space. Wall mount cable by using tie-wraps. Wall mount cable by using decorative raceway. Wall mount cable by using gutter. Mount cable by using a ladder rack. String cable by using a telepole. String cable by using fish tape. String cable using pull string. LAB 9.5.1 DEMO CABLE INSTALLATION - ANSWERSProper technique is described in the curriculum, learning objectives 9.4. Safety must be emphasized first, then professional installation (quality punchdowns, proper cable routing and mounting procedures. It is probably most efficient to have the students demonstrate their skills in teams.There is considerable flexibility with this lab and there are many options for how to run the cable. Answers will vary considerably. The necessary tools and samples of components should be available for demonstration. Some or all of the following cabling tasks can be demonstrated by the instructor and performed by the students depending on the resources and facilities available. The main things to look for are clean and neat cable runs with no kinks and good connections. At a minimum the students should punch down an RJ45 jack and run a piece of cable to a patch panel to simulate a cable run from a workstation from a PC workstation are to an IDF or MDF.Fish cable from above.

Lab 9.7.13 Demo Cable Testing Estimated time: 30 min.Objectives:Use the Fluke 620 (or equivalent) to perform cable verification experiments on newly installed cable runs Background:In lab 9.5.1.1, you were supposed to do a cable installation. As part of that lab, or as part of a project, you should complete the cable run installation by punching down into an RJ-45 jack on one end and a patch panel on the other. In this lab you are called upon to test this cable run. There are a wide variety of tests and a wide variety of equipment that you could use. In this lab you will learn two techniques, one using a simple cable continuity meter and the other using a more sophisticated Cable Test meter.Students should demonstrate the ability to use simple continuity-level cable testers. Instructors should at least demonstrate cable testing to the level of a Fluke 620 CableMeter or equivalent. If more Fluke meters (or equivalent) are available, then training all students on these meters will give them enhanced professional skills. If available (perhaps on loan from your regional academy or a local cable installation company), demonstrate the use of the higher end cable testers -- they are truly remarkable devices which measure many of the cable parameters discussed throughout the curriculum.Tools / Preparation:You should be familiar with the use of the Fluke 620 and basic cable testers from the Chapter 5 labs on media. The following resources will be required:One completely installed but untested cable run (RJ-45 wall jack to cable to patch panel) per student group Fluke 620 CableMeter or equivalent Common RJ-45 cable continuity meter Journals Tools and materials for lab 9.5.1.1 if the cable run fails the test and must be redone High-end Cable Testers (attenuation, NEXT, FEXT, ) if one can be borrowed from a local company or regional academy WorksheetYou should be able to take the cable run created in Lab 9.5.1.1 and test it. Your instructor will demonstrate some of the tests that can be performed with a cable tester. In some instances, the tests will indicate that problems exist. You will be asked to outline how you would determine what the problem is, and describe how you would fix it.Complete a Cable Run:Use the Fluke 620 Meter on Wire Map to test the installation: Identify any faults at near end, along the cable, or far end. Correct the faults:Retest until the cable run passes on the Fluke Meter: Label the Cable Run (alphanumeric identification) as passed and record in your journal. (optional) Using the continuity meter, test two straight through patch cords one can be short, but the other must make up the entire rest of the distance from jack to patch panel. Test both patch cables on the continuity tester:(optional) Connect both cables to the continuity tester. If all of the light pairs (1 to 1, 2 to 2, 3 to 3, etc. up to 8 to 8) light up, you have demonstrated at least the continuity.(optional) Perform high-end tests on the cable run with more expensive test equipment. LAB 9.7.13 DEMO CABLE TESTING - ANSWERSYou should be able to take the cable run created in Lab 9.5.1.1 and test it by connecting a workstation with a NIC to an RJ45 straight-thru patch cable and then into the wall plate (RJ45 jack). Connect another RJ45 straight-thru patch cable from the patch panel to a hub or switch and make sure the switch is plugged in. If the link lights on the NIC and the hub or switch comes on you have a good connection. You can also use the Fluke CableMeter or a basic cable tester to verify the cable run is good using the following steps. Results will vary depending on the resources and facilities available. 1) Complete a Cable Run.2) Use the Fluke 620 Meter on Wire Map to test the installation.3) Identify any faults as near end, along the cable, or far end.4) Correct the faults.5) Retest until the cable run passes on the Fluke Meter.6) Label the Cable Run (alphanumeric identification) as passed and record in your journal.7) (optional) Using the continuity meter, test two straight through patch cords one can be short, but the other must make up the entire rest of the distance from jack to patch panel. Test both patch cables on the continuity tester.8) (optional) Connect both cables to the continuity tester. If all of the light pairs (1 to 1, 2 to 2, 3 to 3, etc. up to 8 to 8) light up, you have demonstrated at least the continuity.9) (optional) Perform high-end tests on the cable run with more expensive test equipment.
