Two SAM1411 in the same shelf must always be set to the same SGA. Otherwise, the software
detects that the FRU information in the two SAM1411s is different and stops the power-up
process. The red LED blinks and the boards are not powered.

Two SAM1411 in different shelves must always be set to different SGAs. When set to the same
