Module Power
The DSP part of the blade uses three separate power domains:
DSP-FPGA 3.3V from the base board and is powered with payload.
DSP, DDR3 memories, and local FPGA I/O banks are powered from dedicated local DC/DC
converters.
IPMC sensors and FRU information PROMS are powered with 3.3V management power.
The local module power domain is controlled by the DSP-FPGA.
