    I have a trivial problem which, however, I cannot overcome.

    In what order (colors) to connect the cables in the plug and socket at the ends of the red cable (diagram below)
    Connecting RJ45 Cat5e Keystone Jack: Proper Order of Colors for Socket and Plug Ends

    I struggled with it all evening yesterday: /
    I have the following marking on the plug:
    http://www.global-b2b-network.com/direct/dbimage/50254880/RJ45_Cat5e_Keystone_Jack.jpg
    At both ends I connected according to the scheme "B"

    When I connected the socket to the tester via a straight cable, all the LEDs were lit in turn, except for the "3" (which was not lit at all) - is that 1 pair of cables is damaged?
    At the end of the cable the LEDs were lit in a different order (of course "3" did not light up either)

    Later I tested by pulling more cables from the socket - then the LED responsible for this pin did not light up,
    but when I pulled out one of them then the tester did not show any diodes - is it supposed to be?

    Here you have the order of the cables:

    On the plug you connect in the order of colors, i.e. white-blue-> green-> white-green etc ...

    It should work :D

    Sorry, but I don't get it a bit :)

    This order "white-blue-> green-> white-green, ..." I don't know any of the graphics you attach.
    You can fill in the following for me:

    Outlet:
    pin 1 - [color]
    pin 2
    pin 3
    pin 4
    pin 5
    pin 6
    pin 7
    pin 8


    Plug:
    pin 1 - [color]
    pin 2
    pin 3
    pin 4
    pin 5
    pin 6
    pin 7
    pin 8

    I assume that pin 1 in both the plug and the socket is on the left side when looking from the front when arranging the plug and socket, so that the fastening clip is at the top.

    Could you send me a picture of this part of the nest?

    Because now I noticed the numbering: /

    You may have made the wrong assumptions. Check out this photo With the arrangement like the ends of the blue cable, pin 1 is on the left pin 8 is on the right.

    And then it is as written above. On both sides of the wall you earn in one standard - with you "B" and years.

    The matter is simple in the sockets. There are three rows of description: one labeled A, the other B, and the third contains the pin numbers in the socket - the actual pin numbers, because the order of the wires is different than the order of the pins , there are "interleavings" made in the socket. The same standard A or B should be chosen on both sides and appropriate colors (there is clearly this color at each position) should be pressed into the socket.
    If A, it will be from left to right: blue (4), white-blue (5), green (2), white-green (1), orange (6), white-orange (3), brown (8) , white-brown (7).
    If B, from left: blue (4), white-blue (5), orange (2), white-orange (1), green (6), white-green (3), brown (8), white-brown (7).

    Then OK comes out according to the pin numbers. And he already gave you the cable kick959
    Whether A or B - it doesn't matter as long as both ends are the same.

    And the cable connection he gave kick959


    that is, when a cable in the wall has a plug at one end and a socket at the other end,
    I do one diagram in both places, eg "B"?
    or maybe I make B in the socket and on the plug a diagram from the cable he gave kick959 ?

    Exactly. Do it in [B].

    Why should I? Sockets on both sides, and the cable from the equipment is inserted into the socket. Why do you need a cable with a plug coming out of the wall? Everything seems to be possible, but this is a terrible makeshift solution.
    Suppose you don't want to plug something in at the moment. If you have a socket, disconnect the cable from it and hide it in a drawer. And you have a permanent cable with a plug, you can only roll it up and put it against the wall.

    To the router - all cables come together in one place and I want to plug them directly into the router. You can make sockets and add cables to them, but why multiply entities

    Your decision, but it's not very professional. See what I wrote above - it is also an argument. It will work, anyway.

    It works! - thanks for the help
