  • 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.
  • Its called Layer 0

Whats 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

    connectivity products that integrates data,
    voice, video and various management system of a
    building

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

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

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

  • Labeling is a key to reduce work later

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.

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

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

    the outside world

SEGMENTACIÓN
  • Existen dos razones principales para
    segmentar o dividir una LAN.
  • Aislar el tráfico entre segmentos.
  • Obtener más ancho de banda por usuario para crear
    dominios de colisiones pequeños.
  • Si no existiera la segmentación, las
    grandes redes LAN rápidamente serian invadidas
    por tráfico y colisiones, y provocaría
    virtualmente en falta de ancho de banda. Los
    dispositivos como bridges, switches y ruteadores
    segmentan la red LAN.

56
SEGMENTACIÓN
57
SEGMENTACIÓNBridge
  • Es usada la segmentación usando bridge para
    proporcionar mayor ancho de banda.
  • El bridge permite sólo la información que tienen
    destinación fuera del segmento.
  • Aprende una segmentación de red para construir
    tablas de direcciones que contienen las
    direcciones de cada dispositivo de red dentro del
    segmento.

58
SEGMENTACIÓNBridge
59
SEGMENTACIÓNSwitch
  • El propósito de la segmentación usando switch es
    que es fácil reducir los cuellos de botella de
    red.
  • Un switch segmenta una LAN dentro de
    microsegmentos.
  • El switch determina cual es la acción a tomar
    sobre la información si esta localizada en otro
    segmento, la información se transfiere o switchea
    a otra destinación.

60
SEGMENTACIÓNSwitch
61
SEGMENTACIÓNRouter
  • Los ruteadores crean los mayores niveles de
    segmentación debido a su habilidad de realizar
    determinaciones exactas de donde enviar la
    información al usar su tabla de ruteo.

62
SEGMENTACIÓNRouter
63
Internet Conections
  • Actually conects to other networks is cruatil in
    many home and organizations specially with
    Internet.
  • We need to rent a contract with a Internet
    Service Provider to connect with remote networks.
