Freaked by colour codes

Part One. :)

I don't understand the colour coding for the wires on my front panel connections.

The mobo diagram is marked with the positive and negative orientations but I don't know which is which. I've got;

Speaker red/black (This I understand :) )

Reset switch Blue/white

H/D LED orange/white

Power switch Grey/white

Power LED green/ white

Which are + and which are - ?

Hi

The only ones it matters with are the LED connectors, and i think for the

HD Orange is +

Power LED Green is +

But as Lord Lucan has said all that will happen is that they wont light up if they are wrong.

Cheers, chaps. I'll just treat white as negative.

Part Two. :)

The two front USB internal connections terminate in four individual one-hole connectors. They are marked;

Data +

Data -

GND

VCC

The mobo connections are listed;

1 Power

2 Power

3 USB Dx-

4 USB Dy-

5 USB Dx+

6 USB Dy+

7 GND

8 GND

9 No Pin

10 NC

Am I right in assuming this;

1 Power = VCC

2 Power = VCC

3 USB Dx- = Data -

4 USB Dy- = Data -

5 USB Dx+ = Data +

6 USB Dy+ = Data +

7 GND = GND

8 GND = GND :)

What does ' No pin' signify and what's NC ?

EDIT; I wouldn't be posting this except it says in red letters ' Wrong polarity at this point will blow your USB to hell'

no pin means no pin,some connectors have a bit of the connector blanked off,so you cant fit it the wrong,i.e the one blanked off with no hole goes into the no pin.by the way moon get this wrong and the mobo could blow up in your face when you turn it on,maybe :lol:

that happened to me once, i put a pin on a connector that said no pin and there was a loud explosion, i didnt wake up until the week after, and then i only had 3 fingers left on one hand...it was most traumatic, so be careful mr moon.....

Hmmmm. OK. :D

Next up is rear USB. I've connected the front USB as above (2 of), the mobo has 2 more rear USB ( inbuilt) and I've got 2 more with rear fittings and connector cable that I can't find a mobo socket for. The specs. say 6 USB. Who's got my other USB connector ? The only other 9-pin connector that I can find is reserved for the front Firewire socket.

So K, ellas, I've sussed it. There are two sets of 2x integrated USB ports on the mobo. I've only got 2 left over because I've used the case front ports. I own my first spare part B) :D

Is it OK to roll up and secure the IDE ribbons to allow free flow of air from the fans ? No induction or heat problems if I do ?

What does 'Info-Link' mean. I haven't got anything left over to fit on that.

roll up the ide cables???

i take it these ide cables are in use, if so, best not to roll them up, they are simply thin wire and as such quite easily breakable....

try not to get to hung up on air flow and cooling, get the thing built and worry about overheating in the unlikely event of it actually happening!
