In the before times we would make something called a crossover cable to allow two network cards talk to each other without a switch or hub between them.
More like a rollover cable for something serial related rather then a crossover cable.
my first thought, but it doesn’t really make sense since I’m not sure crossover is a completely reversed version of straight. Also this cable leads down to an actual patch panel.
Yeah, a crossover cable is pins... 3 and 6 switched? iirc. I did not remember correctly, it's 1/3 2/6, been a while. The greens and oranges swap places
Either way, if the cable was reading completely reversed, assuming it wasn't fixed by rewiring it, check the patch panel to make sure that's wired right if you haven't. One of the first mistakes I made in college was wiring a patch panel backwards xD
Besides that the only thing I could assume is the direction one end got termed was just backwards. If someone's in a rush I could see them just absentmindedly mounting the head backwards.
We’ve been spoiled by Auto MDI/MDIX being standard on everything now
I for one and happy with being spoilt.
