When using an M340 with expanded backplanes, does powering down one expanded backplane affect the others?



No. As long as the hardware connections for the BUS remain intact, simply turning off one of the expanded power supplies will not affect the other backplanes. The power supply is used only to power the IO modules and does not affect the BUS signals.
