IPlease make sure that each of the power supply units is connected to a different phase. This will provide you with additional phase redundancy for high availability configurations. If one phase has failed, the power supply units connected to the other phases keep active. You can get full phase redundancy with up to three power supply units. With four power supply units, two of them are to be connected to one phase (see also “Related Publications” on page 165).
Phase redundancy is possible in regions, where a single phase provides 200 - 240V; in other regions with lower single phase voltage, two phases must be coupled and complete phase redundancy thus is not possible.
