If both LEDs D16 and D17 are off, replace PIB as described in “Removal 

and reinstallation of the power interface board (PIB)”

IRIS board diagnostics

 Figure 8: IRIS board indicator LEDs

To verify if the IRIS board is defect, check the FPGA LEDs on the position n°1

and n°2. They light up orange after start-up and should go out when they are

configured. When one of those FPGA indicator LEDs does not go out, the IRIS

board is defect. The display unit should be send back to Barco.
The Freescale LED should light up green during operation. This LED is only for

development purposes and will not be present on the new version of the IRIS

board.
