Can a 2240-4 run off of a single power supply?

[VIRTUALLYMIKEB]

The FAS2240-4 comes with four power supplies.  If three of them fail for some reason, can the system run on just the one remaining power supply?

No. It needs at least two PSU providing power. It also needs all four PSU fans; physically removing PSU will cause shutdown after 2 minutes.

they require a minimum of one per controller/per shelf. Anything less and they will shut down
