I have a H8SGL-F and it won't boot up. The DP2 LED is on and blinking, but the DP3 is not. What is the DP2 LED for? I can't find it in the manual.
DP2 LED is for the IPMI. If it’s blinking that means the IPMI is on and working.
DP3 is the motherboard power status LED, if it is not on then that means the motherboard doesn't have power.
