you know the computer thing is it plugged in?
A community for memes and posts about tech and IT related rage.
Tab down, orange white, orange, green white, blue, blue white, green, brown white, brown.
But in all honestly as long as the cables match on either end it doesn't matter even in the slightest what color they actually are so I never understood why they used such weird pairing either.
It matters for longer runs and higher speed. The twist provides noise cancellation effect
It matters that you do the pairs right. CC-B-AA-B-DD. It doesnβt matter which color is which, except to make it easier to get the ends to match.
I thought that you mean the color doesn't matter just that they match on the termination point, not as a pair. So you can have C with brown and green for example
That you cannot do. Or at least youβll have a lot of connectivity problems if you do.
Which is why I said it matters for long run. A short cable run would still probably work even if suboptimal.
For certain values of βworkβ I suppose. Youβll get a link light, probably.
dick down, orange to brown
If you're blue inside, it ends in shit
When Metcalfe created Ethernet it was Thick Coax. Ethernet over twisted pair was standardized by TIA. They didn't fuck with it. They created it. Before that it was vendor specific.
I don't know where they found it, but the WISP who ran Ethernet from the antenna to the router in my mom's house used white jackets for every wire pair.
Yeah, why is this the case? I have to refer to a diagram whenever I punch down a jack. Always forget where the green goes.
Blue 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.
Swap b and c on one end for crossover
Thankfully I don't need to worry about that for stuff later than ~2010.
Yeah but it still explains the βwhy?β
Useless for 10/100. If you want gig you need the 4th pair.
So, useless for home internet, but useful if you want to use your PC VM on your laptop
They made 2 variations so it could coexist with older Telco wiring.
I 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?
Yeah, 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.
Was 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.
I'm usually the type to just deal with the annoyance and use them up to prevent tossing them. Probably a minor enough annoyance.
