This power cabling option provides you with additional phase redundancy for high-availability configurations. If one phase fails, the power supply units connected to the other phases remain active. You can get full phase redundancy with up to three power supply units. You should therefore connect the redundant power supply units PSU3 and PSU4 to one phase.

This power cabling option is recommended if high availability is required and a connection via UPS is not possible.
