Both STBY LED and BOOT LED are AOpen’s considerate designs that aim at providing you friendly system information. The
STBY LED will light up when power is provided to the motherboard. This is a convenient indication for you to check the system
power status in many circumstances such as power on/off, stand-by mode and RAM power status during Suspend to RAM
mode.
BOOT LED will keep blinking when you power the system on and when your system is under
. After
POST diagnoses everything alright and finishes the booting, the LED will stay on otherwise it will remain flashing to warn you
that mistakes have occurred during POST.

Warning:
Do not install or remove the
DIMM module or others devices when
the STBY LED lights on.
