minus-squareAtropos@lemmy.worldlinkfedilinkarrow-up15·4 days agoYeah, why is this the case? I have to refer to a diagram whenever I punch down a jack. Always forget where the green goes.
minus-squareshalafi@lemmy.worldlinkfedilinkEnglisharrow-up8·edit-24 days agoI sing a little ditty in my head: Orange-stripe, orange, green-strip, blue, Blue stripe, green, brown-stripe, brown. If it’s the “other” scheme? Fuck me, to the diagrams I go. EDIT: Realized you’re talking about jacks. Aren’t they all clearly labelled these days, with both schemes?
minus-squareAtropos@lemmy.worldlinkfedilinkarrow-up6·4 days agoYeah, the good ones are labeled, but I have a bag of unknown origin that don’t have it on the side. I should probably just get a new bag.
minus-squareshalafi@lemmy.worldlinkfedilinkEnglisharrow-up3·3 days agoWas going to say, despite my loathing of waste, I’d probably chunk of bag of unlabelled jacks. Hell, you’ll waste a few fucking up anyway.
minus-squareAtropos@lemmy.worldlinkfedilinkarrow-up2·3 days agoI’m usually the type to just deal with the annoyance and use them up to prevent tossing them. Probably a minor enough annoyance.
minus-squareHawke@lemmy.worldlinkfedilinkarrow-up5·3 days agoBlue in the middle is pair 1. Orange around that is pair 2. Green on the left, brown to the right. CC-B-AA-B-DD. Pair A is for telephone back when Ethernet was wired to a punch down block. Pair B and C are for data. Swap b and c on one end for crossover. The fourth pair is basically useless.

Yeah but it still explains the “why?”
