Need help hooking up front button, colors messed up.

[dave343]

I've hooked up the front buttons to boards a million times but this time it got me, I'm stuck.
I'm trying to hook up the front buttons on my Chenming case to my Asus P5NSLI board but I'm not sure if the wires were color coded correcly.

Usually I've always just looked at pin one, then went right across looking each time at the PW button or the Reset button and where ever the arrow is on that jumper I place it towards Pin 1. Problem is some of the arrows/pin1 on the cables have white/green and some have black, but I always though black was negative. Take the speaker cable for example.
The arrow indicating pin one is black and the other side is red. Is this correct? Which side is the speaker? Half the cables are the same way in that where on the board it's say +5v goes first, on the actually cable where the arrow is the color is black. If this is confusing sorry, I'm trying to explain it as best as possible. I just don't want to blow the board. Thanks in advance for any help. Is black usually positive or is the color?

only thing I can help with is the speaker, if its is the small "beep" speaker built into the case it will not matter, connecting it backwards will not hurt a thing.

Same with reset and power buttons, they are just shorting out the two pins to signal the board to reset or start up. (But it would irk me not to have them just right too, but they will work fine connected either way).

For your LEDs - HD and PWR it wont hurt to connect them wrong, I have done it a zillion times, and when they dont light up, just reverse the header plug and you are good to go.


The above does NOT apply for 2 speaker stereo speaker systems where care must be taken for both speakers to be connected exactly the same way or speakers with their own built in amplifers.

in electronics black is usually negative
in electricty (house wiring etc. ) black is considered "HOT" postive.

That little inconsistancy has almost killed me a couple of times.
