DESCRIPTION

Network cabling

TRANSCRIPT

  • Peel off about 4 cm from wire and take the wiring pairs out as shown in following figures

  • Then take out the keystone jack (information outlet) and based on 568 B wiring standard put the appropriate cables in correct slots as indicated in colors and do the punch down.

  • When you punch down the edges of the wires will cut away and leave nice smooth connection as shown in figure below.

  • Then correctly roll in the wire and put the keystone jack in Face plate. It is better to check using a cable tester after patch panel side also being punched in.

  • Wiring Patch panel

    Wiring patch panel is bit difficult than wiring information outlet. Because patch panel consist of facilities to connect 24 to 96 wires at a stretch.

    Therefore it is important that you manage the wires properly inside cabinet and peel off the wires and connect according to color codes specified in patch panel.

  • If your wall outlet is connected using 568 B standard you have to connect wires to patch panel also in 568B standard.

    Then the wiring remains straight throughout the distance from patch panel to wall outlet.

  • After connecting wires to patch panel using punch tool, you can connect patch cord from appropriate switch to patch panel.

  • The numbering system of the wall outlet and patch panel has to match that will help in tracing the cable properly.

    People use one or more combinations in numbering their network outlets in user end as well as in distribution end.

    Like (Distribution point id closet id panel id port id), for example MDF5-P1-22 means the 22nd port in panel 1 of Main Distribution Frame 5.

  • Based on these guide lines you can make your network properly cable routed and managed.

    1. Use proper insulations bends, or cable junctions and use conduits when routing above ceiling (to prevent rodents from damaging cables)

  • 2. Draw network wires away from Electrical wires as much as possible

    3. Always use UTP / STP cables inside buildings. If you route cables in outside corridors and areas where wet conditions persist the cabling is prone to induce lightening which will be a total disaster.

    4. Use cable ladders and cable ties and do proper numbering of cable while being drawn from one location to another, if possible number every 10 M so that you can trace the cable in the middle of wiring easily.

  • 5. Do proper termination of cables, leave all additional cables rolled and tied in neatly for moving of cabinets and future expansions.

    6. When you do a change or trouble shooting always remember to put the cables in properly into cable management so that the wire organization will not be affected.

    7. Do proper electrical cabling to cabinets and adjoining areas with sufficient power for future expansion of fixing extra equipment.

  • Above steps will prevent the congested and unorganized nature of network cabinets.

    The picture given below is a data center which has bit of unorganized nature.

  • The below diagram shows a well organized data center.
