Can the power supplies be placed on separate input circuits?
Yes. Each power supply has its own AC cord. The top power supply in each enclosure can be placed on Circuit A; the bottom power supply can be placed on Circuit B so that if a breaker trips in the datacenter there will still be power supplied by the other circuit. This wiring configuration, especially popular where multiple enclosures are installed, provides a level of fault resiliency. In addition, Cubix internally wires its PR3000 47U rack cabinet to take advantage of connecting to multiple circuits.
