SRCU board doesn’t receive satellite signal even when all connections looks like OK.
No satellite traceable to BSRCU
We did a detailed checking of the hardware and found a strange defect of the board, the supports of the module were longer than other SRCU board (You can see photos in attachment document), so satellite module doesn’t make physical contact with the SRCU (pins don’t enter to receiver).
We changed these supports for other shorter and then the same board was able to receipt satellite signal.
It is possible that the problem was the module but we tried to connect the board in slot 12 too and alarm appeared again. We tried within 3 different modules but the problem continued.
Check in detail the hardware and the right connection between modules before take the decision of change a board.
