12.5.1 Checking correctness of feeding on board 151-506
After turning on the power supply diode signalizing proper functioning of random parts of
board should shine.
If diodes LED 1 or LED 2 doesn’t shine check voltage on connectors X1 and X5.
Tab. 3 Voltages on connectors on board 151-506
If voltage on connectors X1 and X5 are proper, although LED1 or LED2 doesn’t shine we qualify
board 151-506 as broken and perform its exchange. If there is no powering voltage, check power
supply board (see: Switch source power supply).
