I have hardware question.
I am running a duplex CAT7 cable from a patch panel to a wall socket. One connection works, the other struggles when I test the cable.
Below I describe how I tested the cable and what the able tester shows. Maybe someone can explain what went wrong.
I connect the active unit of the cable-tester (WITHOUT the passive unit at the other end) to the patch panel and
no LEDs light up. That seems correct. So far so good.
I connect the active unit of the cable-tester (WITHOUT the passive unit at the other end) to the wall socket and the LEDs for cable
3and6(orange + orange/white) light up. That seems faulty. See attached image...I connect both the active AND passive unit (as you would normally use this tester)
all LEDs light up except
3,6-> inversed result of test before.Gnever lights up in any test
