Power Supply

A minimum of one 1000-Watt power supply is required to turn on a compute module.
One power supply will support 1 compute module plus all other modules in the system.
Two power supplies will support 2 to 3 compute modules (in any slot) plus all other
modules in the system.
Three power supplies will support 4 to 6 compute modules (in any slot) plus all other

Any additional power supplies above minimum required (based on configuration)
