My an initial build.The 3 leads comes from the front-panel on my Cubitek MiniTank instance (ON/OFF, RESET, HDD LED) have two black wires each. On each of these leads, one of the wires is significant with a small arrow top top the connector. What is the convention? does the arrow indicate ground wire and the negative? Or the power-wire and the positive?Thanks

For the strength switch and reset switch polarity is irrelevant. They space both only momentary call switches.The HD_LED is the just connector that the 3 where polarity is critical.If there is a triangle ~ above the connector that is the indicator for the positive lead.

download the entire manual for the plank from the manufacturers website.It will display the connections with all the details.
Even if over there is a convention, the doens"t average that the situation manufacturers followed it. Girlfriend should inspect the hand-operated for the case.For example, black color should constantly be ground/negative. In common wiring, you have red/white = positive, black = ground/negative, green/bare copper = ground. If over there is no green, then black color is ground. This is a straightforward convention that any type of electrician should follow. Due to the fact that you have actually two black wires, the case designers to be idiots. Did you inspect to check out if one of the wires is black with a stripe? If so, that wire would be positive, and also the solid black color wire would be ground. If the isn"t the case, climate I"d guess the the black color wire through the arrow is positive, and also the one there is no is ground.
The "manual" because that the Cubitek Mini Tank is a solitary one-sided oversized item of record in many languages, folded like a city map.The ar on former i/o harbor installation
covers USB (it says 2.0 yet the USB cables say 3.0) and also HD Audio only. Over there is nothing about the strength ON/OFF, RESET, or HD LED wiring. The wires room not multicolored or black and also white, and I don"t see any kind of stripe, however there is some minuscule lettering top top the wire that is marked with the triangle ~ above the connector. Opposing wire has no print on it.

The ASUS hand-operated is fairly clear. It"s differentiating which wires are which top top the front-panel leader (power, reset, hd_led) the is the problem. I know which pairs of pins ~ above the m/b go v each that those three leads native the front-panel, just not how to orient the two-pin connector top top the pair the pins.
For the power switch and reset switch polarity is irrelevant. They room both only momentary call switches.The HD_LED is the only connector that the three where polarity is critical.If there is a triangle on the connector that is the indicator for the positive lead.
