I can see four spots on the Blackbird board having LEDs in different colors and blinking/non-blinking.
What do the diverse LEDs on the board signal?
I have looked at the schematics (delivered on the recovery CD) and also read the labels printed on the PCB but I cannot find answers.
My current interpretation is:
- Top right corner: Standby PSU Act: The orange power status LED on the mainboard will turn green if the system is powering on.
- Top left corner: Status LEDs BMC (green, blue, orange) labled: Net1, Net2, HDD, UID, Power, Net3 - blue lights mean booting of OpenBMC
- Bottom left corner: D7000 near AST 2500 (always blinking in green) - LED green PM BMC Reset (PM_BMC_HBLED_R_L)
- Bottom center: D10103 Reset - always on, green light
