15) F_USB1 / F_USB2 (Front USB Connectors)
Be careful with the polarity of the front USB connector. Check the pin assignment carefully while you
connect the front USB cable, incorrect connection between the cable and connector will make the
device unable to work or even damage it. For optional front USB cable, please contact your local
dealer.
16) CI (Chassis Intrusion, Case Open)
This 2-pin connector allows your system to detect if the chassis cover is removed. You can check
the "Case Opened" status in BIOS Setup.
