Notes

Each FMC+ slot has its own VADJ rail (FMCA_VADJ / FMCB_VADJ), generated by a dedicated Enpirion EN63A0 regulator; the user guide (UG-20047, shared with the H-tile DK-SI-1SGX-H-A variant, which does not differ for VADJ) lists supported values of 1.2 V / 1.35 V / 1.5 V / 1.8 V per rail. The guide does not document how the voltage is selected or its boot default — there is no VADJ jumper in the factory switch settings, no Board Test System control, the VADJ rails are excluded from the LTM2987 / Power MAX 10 voltage-trim functions, and the FMC I2C buses route to the FPGA rather than a power controller — so there is no documented auto-negotiation from the FMC IPMI EEPROM. Verify the selection mechanism against the board schematic before relying on a specific VADJ value.
