HOW TO INSTALL THE CABLE UTP STRAIGHT TYPE AND CROSS



before you practice, there is some hardware that you need to prepare, including :



  • UTP (Unshielded Twisted Pair). UTP cables are frequently used categori 5 UTP cable (UTP Cat-5). why? for Cat-5 UTP cable support data transfer up to 100 Mbps. This cable consists of 8 small that have different colors. The cable color is orange, orange and white, blue, white, green, green, white, brown, white chocolate.

  • the second is the RJ-45 jack. jack is similar to a home telephone jack. only the larger size. RJ-45 jack consists of 8 pins, according to the number of UTP cables

  • crimping tool or crimping pliers. hardware that is similar to a pair of pliers. however, unlike its function pliers in general. crimping tool is useful to clip the cable to the RJ-45 jack. 
all the above hardware can be found at most computer stores. the price is not too expensive.

 UTP cable straight type
 

I will now discuss how to install. The first is how to install UTP cable straight type. for it to do the following steps:


  • peeled end of the wire about 1 cm, so that the small wires that are inside look.


  • attach the cables and straightens. then collated and the trim on the white color is orange, orange, green, white, blue, white blue, green, white and chocolate brown. after it cut the edges so that the average of each other.


  • after a structured cabling, RJ-45 jack grab. as I said earlier this jack consists of 8 pins. pin 1 of the jack is located adalahpin the left if your facing the pin position. sequential to the right is the jack 2, 3, 4, and so on. 


  
  • then insert the wires into the RJ-45 jack in the order was as follows:


  1. Orange-white on pin 1
  2. Orange to pin 2
  3. Green-white on pin 3
  4. Blue on pin 4
  5. Blue and white on pin 5
  6. Green on pin 6
  7. White chocolate on pin 7
  8. Brown on pin 8 
         insert the cable until the tip is stuck in the jack.

  
  • insert the RJ-45 jack which is mounted with the cable before crimping pliers in your mouth corresponding to the pin RJ-45 jack in the mouth pliers. now had a jack flops tangcrimping pin sticking up all over the wiring. usually if the pin is stuck jack will give voice "click".
now you've finished installing the RJ-45 jack on the end of the first cable. to the second end of the cable, the steps are the same as the first one end of the cable installation. to repeat the earlier steps to install the RJ-45 jack on the end of the second cable.
UTP cable straight type arrangement you can see in the picture below:

UTP cable type cross
 
how to install UTP cable straight type I described earlier. Now I will discuss about how to install the type of cross UTP cable. UTP cabling to cross almost the same type by placing a straight UTP cable types. about the same as before the technical installation. the difference is the color sequence of wires at the second end of the cable. The first end of the cable, the cable structure with UTP cable straight type arrangement are:

 

  • Orange to pin 1
  • Orange-white on pin 2
  • Green on pin 3
  • Blue on pin 4
  • Blue and white on pin 5
  • Green-white on pin 6
  • White chocolate on pin 7
  • Brown on pin 8
to the second end of the cable, the color arrangement different from the first end. As for the arrangement of the colors is:

  • Green-white on pin 1
  • Green on pin 2
  • Orange-white on pin 3
  • Blue on pin 4
  • Blue and white on pin 5
  • Orange to pin 6
  • White chocolate on pin 7
  • Brown on pin 8
composition had wiring you can see in the picture below

the end result will cross UTP cable types like this:

CP : white chocolate

the conclusion is if you plug in the UTP straight type arrangement of colors on both ends of the cable is the same. whereas UTP installation way cross type, color composition different from the first end of the cable end of the second cable.
