11) CI (Chassis Intrusion Header)
This motherboard provides a chassis detection feature that detects if the chassis cover has been re-
moved. This function requires a chassis with chassis intrusion detection design.
12) PWR_LED (System Power LED Header)
This header can be used to connect a system power LED on the chassis to indicate system power
status. The LED is on when the system is operating. The LED keeps blinking when the system is in S1
sleep state. The LED is off when the system is in S3/S4 sleep state or powered off (S5).
