Board status lamp indicator states
Lamp state Symbol Meaning
Off

No power.

The board is not powered or the power distribution network is not functional.

Solid green

Board status OK.

The main power distribution network is operational and the FPGA start-up procedure has successfully completed.

Solid red

Board status NOK.

Possible causes are:

  • There is no power delivered on the +12 V rail of the PCI Express connector slot
  • The FPGA start-up procedure is not completed. The normal completion time is around 100 milliseconds.
  • At least one power converter of the main power distribution network is unable to operate properly. This might be caused by excessive temperature due to inadequate board cooling, accidental short-circuits having blown one (or more) protection fuses, inappropriate supply voltages, etc.
