Note
Four power supplies must be installed in the chassis at all times, with a minimum of two power
supplies (one per zone) connected to the mains in order to power on the system and ensure
sufficient cooling. The system fans are inside the power supply units and must spin for cooling.
Because all the system fans can be powered by one power supply, the second power supply unit
does not have to be powered on, but must be connected.
