Hi there, silly little issue here. I am attempting to build a NAS with the Jonsbo N3 and a Supermicro X10SDV-4C-TLN2F. The front panel header cables on the N3 are fused together and do not line up with the esoteric layout on the motherboard which forced me to buy split front panel extender cables but then I ran into a problem. There are only 4 cables for the front panel (the backplane handles the rest): The power switch positive and ground are side by side so no issue there but there is a 3.3v terminal right beside the power LED terminal, which I assume would fry it (and maybe the board). There is an unused ground terminal, next to the unused reset switch terminal and the power LED cables are split. In summary: Can I safely reach the negative/ground power LED cable over to another ground terminal on the front panel header without issue or do they need to be side by side and thus would not work with this board. An insanely inane question, I know, but I have never encountered this before and just want to make sure that I do not damage anything. Thanks.

All components work together within the computer setup, so you can safely use the other terminal. Even if you mistakenly connected the negative power lead to 3.3v, it won’t damage anything. The voltage across the LED is adjusted to prevent it from turning on, and because it’s a diode, it stops current from flowing backward into the motherboard circuit.

It's interesting Supremicro isn't adhering to the usual standards. I'm curious about the reason!

I frequently came across the instructions stating uniformity across their frames, implying they built these features prior to the ATX standard or intentionally kept them vague to complicate third-party compatibility.

Looking back it all fits perfectly. What will happen to the ground if we don’t use the 24-pin connector? Also, appreciate the details about the LED function.
