2.2.3.4.1 Hard Drive Activity LED Header
Pins 1 and 3 can be connected to an LED to provide a visual indicator that data is being read from
or written to a hard drive. Proper LED function requires a SATA hard drive connected to an
onboard SATA connector.
Note: When using the new M.2 SSD with PCIe there might not be any HDD activity if the storage
vendor has not implemented that function.
2.2.3.4.2 Reset Switch Header
Pins 5 and 7 can be connected to a momentary single pole, single throw (SPST) type switch that is
normally open. When the switch is closed, the board resets and runs the POST.
