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

Published date: 28 October 2019

Need to power down an single expanded backplane for maintenance, but do not want to bring the CPU down.

As long as the hardware connections  (cables and terminators) 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 wiring or termination.
