Front panel wiring.

post #1 of 14
Thread Starter 
I made the mistake of yanking out the plugs from my case button/light panel, and now I dont know which way they go.

I can figure out which is which by looking at the circuit board, but don't know which is +/-. Also, how can you tell which side the lettering should be on the plug? Are there standards for these things?

I know this is a total noobie question, but thats what I am.

I think where the arrow is is where the negative is but not 100% sure on that one. Everything should be in the motherboard book if you still have it. If need be just test them either way, it won't hurt anything.

if they are just switches and no LED it doesn''t really matter which is +/-. switches just completes a circuit. if you are connecting a LED make sure you know which is +/- and ground. from my experience, if you connect the LEDs wrong it won't come on, but if you get them right they will shine. no harm is done conencting the LEDs incorrectly.

The arrow on the plug btw, should be a little tiny one like a triangle shape.

I always use the white wire as the - and the color wire as the +. With the speaker wire, the red is + and the black is -.

Thanks guys, you set my mind at ease, I have a brand new mb coming tommorrow and I dont want to fry it. Luckily the usb plug is idiot proof and is the same either way you plug it.

Thought I had it until I remembered the wires to the leds on the case door. .

There aren't enough pins so I'm not trying to figure out which is the shared ground, between the leds and the power switch . .

There is no manual for this case. It's made by a company that makes server cases, so they probably assume the user knows what they are doing. I'll find out tommorrow I guess . .

The connectors should at least be labeled PLED, SW, HDD etc. If not, trace the wires back to their respective switches and LEDs. Also, the USB MB connections have to go in a certain way. The wires are usually color coded (I havent come accross any that arent), so make sure the power (red) goes to the opposite side of the missing pin on the motherboard header itself.

This one has is a bit different I think since there are 2 sets of Leds. There are no missing pins, there are 2 too many plugs though.

If they are sharing ground, which one would they share?

See if you can take a picture... That would help tremendously!
