  12. 12. Cable Connectors – II – 210 Patch Plug – Uses internal pair isolation, pair-to-pair compensation and layered contacts – Token-Ring Data Connector – Used on end of a shielded twisted pair cable• Distinguishing Wires – Color coding makes identification each wire or pair of wires in the cable easier – Tip and ring – Identifies plus wire and minus wire
  13. 13. Cabling Tools• Used in networking to work with wires or devices or to connect wires and devices to each other• Different tools used are: – Punchdown Tools – RJ45 Crimping Tool – Coaxial Cable Crimping Tool – Pin Crimping Tool – Cable stripper
  14. 14. Working with Cables• Installation works in three stages: – Running cable from central point to the room – Wall jacks are mounted and cables ended into jacks – Wire cables from the central end to switchboard• Color Coding – Helps to classify different types of wires – Patch cable and cross over cable can be differentiated on the basis of colour coding
  15. 15. Working with Cables – II• Tools and materials required for crimping cable: – RJ45 Crimping Tool – Wire stripper – Wire cutter – RJ-45 plugs – Cat-5 UTP cables
  16. 16. Working with Cables – III• Straight through Cable – Same pin out connections at both ends – Used to connect dissimilar devices  Crossover Cable  Modify pin out connections at one end  Used to connect similar types of devices
  17. 17. Working with Cables – IV• Weak Link – Mostly, weakest link is the station cable, which runs from wall to desktop• Information Outlet – Protect horizontal wiring from physical handling that cables receive – Keep installation neat and eliminate unsightly snake pit of unused cables coiled on floor• Station Cable – Runs between information outlet and network node e.g. PC
  18. 18. RJ45 Modular Outlet• Device used to connect shielded or unshielded cables• Acts as extension where wires are fixed on the either side of modular connector
  19. 19. Grounding• Two wires that come from the transformer are called the hot wires usually RED in color and neutral wire in BLACK• A large building requires more than one earth ground and the earth ground between two buildings is different in different situations• Fiber optic cable is the best option to link buildings• Power grounding problems are two types: open or high resistance ground or an abnormal pulse or condition between power conductors
  20. 20. Closet• Main point in an organization where major networking cabling come together• Equipment in a wiring closet includes: – Patch panels for vertical wiring – Patch panels for horizontal wiring – Wiring hubs – Uninterruptible Power Supplies• Types of wiring closets: – Intermediate Distribution Frames (IDF) – at least one IDF per floor for a multi storey building – Main Distribution Frame (MDF) – where the inside cable plant meets the outside world’s connectivity. All IDFs throughout building are connected to MDF in a star topology
  21. 21. Closet Details• Typical equipment in a wiring closet are: – Backbone wiring cross-connect device – Horizontal wiring cross-connect device – Patch cables – Wiring hubs – Backup power for wiring hubs – Router and modems – Access server – Fire Sprinkler System The layout for the equipments in a wiring closet are put on the wall or in an equipment rack
  22. 22. Cross-Connect Devices - I• Make easy to configure horizontal and backbone wiring• Terminates cable or group of cables• Adaptability is easy when the organization grows year after year• In data networks – Small cross-connect device will terminate backbone cable and make it available for connection to wiring hub• In wiring hub – Larger cross-connect device will terminate horizontal wiring before it enters hub
  23. 23. Cross-Connect Devices - II66M Punch Down Patch Panel Block
