CAUTION!
If a power supply unit fails in a non-redundant configuration of power
supply units, and the remaining power supply units do not provide
sufficient power, the system unit is shut down immediately.
I
Make sure that the individual power supply units are connected to
different AC sources. This ensures additional AC source redundancy for
high-availability configurations. If only one AC source fails, the power
supply units connected to the other AC sources remain operational.
Phase redundancy is possible in regions where the single phase
provides 200 - 240V; in other regions with lower single-phase voltage,
two phases have to be coupled, which means that full phase redundancy
is not possible.
