Hi Joel,
Yes, but a separate and distinct power distribution for that +5 volt
supply will then need to be implemented on the system board to support
a full IPMI implementation residing on the system board. That was my
point. You are confusing power source with implemented PCB power
distribution.

Thanks,
Karen
