I need to connect my case's front control panel LEDs: HDD LED & PWR LED to X11SCL-LN4F. On your Quick Reference Guide both of these label only one pin each, 14 & 16, the opposite odd pins being labeled UID SW and 3.3V respectively. My case's connector cables each have Positive and Negative connectors. Please advise what to do with the cable Negative connectors.
Unfortunately it does not support cable negative connectors for front control panel pins, please refer to our website for optimized chassis for X11SCL-LN4F.
