I have a cat6 wired home network and have been trying to replace the jack for one of the cables but there seem to be an issue. When I use the cable tester, I see this sequence: 1, 2, 3, 4, 5, 6&8, 7, 6&8. I tried redoing it many times and I keep getting the same result. I am guessing there is a short circuit somewhere, but not sure how the coloured cables map to the LEDs. With T568B setup, is there a standard mapping to the coloured cables that I can use to figure out which two cables are short circuiting? I can keep removing the cables 1 by 1 and add them back, but there is not much cable left outside of the wall so I do not want to keep cutting them out.

Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Sep 18 '22 at 20:17

A Google image search for "t568b" will show you plenty of images with the information you are after.
6 is Solid Green 8 is solid Brown.
I hope Im wrong but it sounds like someone has damaged the cable in the wall (maybe with a staple / nail? Either that or the wires have been stripped which would be very wrong technique.)

I know in t568b the order of cables are: 1: striped orange 2: orange 3: striped green 4: blue 5: striped blue 6: green 7: striped brown 8: brown Do you mean the 1-8 LED represent the health of 1-8 cables, **respectively**? In which case it makes sense if solid green and solid brown are short circuiting somewhere – Reza Jooyandeh Sep 18 '22 at 21:54

1Yes, the 1-8 on the standard cable testers represent the respective pins. – davidgo Sep 19 '22 at 01:37
