    Hello,
    I am posting a small schematic, because I want to understand the principle of operation of ... the whole.

    As you can see in the diagram, going from the bottom, I have a SIMPLE patch cord earned in the T568B standard, on the one hand it goes to the Switch, on the other it goes to port 1 to the Patch-panel.
    At the back of the patch panel, I sew the cable according to the instructions given on the patch panel ---> then the infrastructure cable goes to the RJ45 socket, which has a DIFFERENT instruction ... as you can see, when connecting according to the instructions from the socket, the wires will be swapped ---> I plug the cable into the socket SIMPLE in T568B standard.

    Understanding Patch Panel's Operation: Schematics and RJ45 Socket Connection

    1. Will it work?
    2. Shouldn't it be that if I make money in the Patch-Panel (PP) according to the PP instructions, then in the RJ45 socket it should be the same as with PP?
    3. I understand the idea of using patch panels as maintaining ergonomics and order in the wardrobe. So why is a patch panel called a patch panel?
    4. When connecting a straight cable to the port in the PP - do I have a crossover cable at the output (at the back of the PP)?

    I will be grateful for your help.

    The cables in the wall are stiff, the veins are wires
    Patchcord cables (pp == switch), cores are soft links.

    Imagine 48 cat 7 cables running to a switch, the sheer force from the bent cables can break the switch.
    or trying to move the switch location by a few meters?

    Added after 2 [minutes]:

    PP port === socket
    it's supposed to be a simple connection, not a crossover.

    In the diagram in PP PORT 1 I have a Switch connected.

    And you mean PP REAR === socket? Consider the unstitched infrastructure cable in PP BACK as the BEGINNING and the END at the RJ45 socket. The point is that at the BEGINNING and END of this cable there should be the SAME connection as at the BEGINNING? So in this case, I'm "failing" the instruction on the socket?

    'net' connection port-rj45-PP ===== socket-in-wall-port-rj45

    So I "leave" the instructions on the PP and the socket and just mount a straight type cable?
    Correct? SWITCH ==STRAIGHT CABLE== PP ==STRAIGHT CABLE== NEST == STRAIGHT CABLE== COMPUTER

    Yes Sir,
    clamp the cables on the sockets according to the T568A or T568B scheme (the same at both ends) which gives 'simple' connections (this ensures the assignment of 4 pairs of twisted pairs to the appropriate pins of the sockets)
