Harry, thanks for your reply.

I was writing vaguely. I was understanding the polarity of the LEDs on the case. I couldn't figure out which pin of the "TO PANEL" connector on the X630-A8 board should have positive polarity. But it resolved. I looked at the packing list. The polarity was written on the silk on the side that was hidden after assembly.

Thank you.
