  7. Structured Cable System • Planning of Structured • Electricity and Ground Conection Regulation • Solutions to drop voltages. • Security Normativity • Network Documentation • Logs • Diagrams. • Labeling Cables • Cable and Power Outlet Abstract • Devices, MAC and IP Addresses • Other resources

  8. Cableado estructurado • Es una metodología para diseñar e instalar de manera adecuada redes de comunicación, particularmente, redes de computadoras. • Define más que una simple estructura o forma de realizar cableados de casas y empresas. Forma un estándar para simplificar las cosas. Se centra en la fase de planeación, instalación y expansión de la red. • It’s called Layer 0

  9. What’s the problem?

  10. Safety Procedures • Safety is the primary concern. • General safety precautions, while working with network building materials - both electrical and construction.

  11. Structured Cabling Systems • A Structured Cabling System is a cabling and connectivity products that integrates data, voice, video and various management system of a building

  12. Benefits of Structured Cabling System • Redundancy at design stage reduces downtime & repair time • Ease of fault location & repair • Flexibility, expandability & modular connecting platform • Ease of moves, adds and changes • Enhanced end-use understanding and control • Significant long term cost containment

  13. Cable Distribution System • Cable Tray • Raised Floor • Conduit • Hung Ceiling / False Ceiling

  14. Elements of a Structured Cabling System

  15. Structered Cabling Components

  16. Foil Twisted Pair

  17. Shielded Twisted Pair

  18. Work Flow • installing outlets • installing jacks • running cables • punching cables into patch panels • testing cables • documenting cables

  19. Work Flow (cont) • installing NICs • installing hubs, switches, bridges, and routers • configuring routers • installing and configuring PCs

  20. Place Copper Wires into a Jack

  21. Documenting Cable Runs • A cut sheet • is a rough diagram that shows the locations of the cable runs. • indicates the numbers of the classrooms, offices, or other rooms, to which the cables have been run. • to place corresponding numbers on all telecommunications outlets and at the patch panel in the wiring closet.

  22. TIA/EIA-606 for Labeling Cables • Labeling • NO terms such as "Mr. Zimmerman's math class," or "Ms. Thome's art class". • incorporate room numbers in the label information • incorporate color coding • For example, a blue label might identify horizontal cabling at the wiring closet only, while a green label might identify cabling at the work area.  • mark the cable three times, approximately 60 cm apart • Allow enough cable for the ends to reach all the way to each jack location, plus enough excess or slack to reach the floor and extend another 60-90 cm. • Do not cut the cables unless they have a label.

  23. Cable Labels

  24. Mounting cables in raceway • decorative raceway • presents a more finished appearance • gutter raceway • a less attractive alternative to decorative raceway. • mounted with adhesive backing or with screws

  25. SAFETY RULES • turn off power to all circuits that might pass through those work areas • Never, ever, touch power cables • learn the locations of all fire extinguishers in the area. • Long pants and sleeves help protect your arms and legs. Avoid wearing excessively loose or baggy clothing.

  26. SAFETY RULES (cont) • Protect your eyes with safety glasses • If you anticipate working in a dropped ceiling area, survey the area. • Follow building safety codes

  27. Supporting Horizontal Cables • Wall-mounted gutter • Tie-wraps • Ladder rack • Tools • A telepole • is nothing more than a telescoping pole with a hook at one end to hold the cable. • is used to string cable across a dropped ceiling or attic quickly. • fishing cable • When you pull cable up through a wall, you ordinarily work from an attic or dropped ceiling space

  28. Wiring Closets • the equipment in a wiring closet includes: • patch panels • wiring hubs • bridges • switches • routers

  29. Network Operating Test • The baseline • is a record of your network's starting point or newly installed performance capabilities. • Continue to test your network on a regular basis in order to ensure that it performs at its peak • A cable tester is a hand held device that can certify that cable meets the required IEEE and TIA/EIA standards.

  30. Cable Tester • Determine cable distance • Locate bad connections • Provide wire maps for detecting crossed pairs • Measure signal attenuation • Measure near-end crosstalk  • Detect split pairs  • Perform noise level tests  • Trace cable behind walls 

  31. Cable Tester

  32. Conexión de cables

  33. Jack El jack es el componente femenino en un dispositivo de red, toma de pared o panel de conexión.

  34. Jack Para que la electricidad fluya entre el conector y el jack, el orden de los hilos debe seguir el código de colores T568A, o T568B recomendado en los estándares EIA/TIA-568-B.1

  35. Configuración

  36. Conexión directa • Utilice cables de conexión directa para el siguiente cableado: • Switch a router • Switch a PC o servidor • Hub a PC o servidor

  37. Conexión Cruzada • Utilice cables de conexión cruzada para el siguiente cableado: • Switch a switch • Switch a hub • Hub a hub • Router a router • PC a PC • Router a PC

  38. Esquema de Conexión EIA/TIA 568


  40. We all have some ugly wiring

  41. Unshielded Twisted Pair Cable • Labeling is a key to reduce work later

  42. Fiber Optic Cable Construction • Fiber has bend radius issues

  43. Fiber Optic Cable Construction • Leave slack loops

  44. Cutting, Striping & Crimping Tools

  45. Punching Tool

  46. Cabling Rules • Try to avoid running cables parallel to power cables. • Do not bend cables to less than four times the diameter of the cable. • If you bundle a group of cables together with cable ties (zip ties), do not over-cinch them. You should be able to turn the tie with fingers.

  47. Cabling Rules • Keep cables away from devices which can introduce noise into them. Here's a short list: copy machines, electric heaters, speakers, printers, TV sets, fluorescent lights, copiers, welding machines, microwave ovens, telephones, fans, elevators, motors, electric ovens, dryers, washing machines, and shop equipment. • Avoid stretching UTP cables (tension when pulling cables should not exceed 25 LBS). • Do not run UTP cable outside of a building.  It presents a very dangerous lightning hazard! • Do not use a stapler to secure UTP cables.  Use telephone wire/RJ6 coaxial wire hangers which are available at most hardware stores.

  48. Cabling Rules • Do not run UTP cable outside of a building.  It presents a very dangerous lightning hazard! • Do not use a stapler to secure UTP cables.  Use telephone wire/RJ6 coaxial wire hangers which are available at most hardware stores.

  49. Standards • Exist a lot of normativity and best practices for the correct construction of cables: • ANSI/TIA/EIA-568-B • ANSI/TIA/EIA-569-A • ANSI/TIA/EIA-607 • ANSI/TIA/EIA-570-A • ISO/IEC 11801

  50. Subsystem of a Structured Cabling System • Horizontal Cabling • Cable from patch panel to work area • Telco outlets • Cable terminations • Cross-connections • One transition point • Maximum length – 100 meters • 90 meters for cable • 10 meters for 2 patch cables
