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 phases. This ensures additional phase redundancy for high
availability configurations. If only one phase fails, the power supply units
connected to the other phases remain operational. You can achieve full
phase redundancy with three power supply units. If more power supply
units are installed, up to two power supply units must be connected to
each individual phase (for information on the electrical connections, see
the technical manual for the PRIMECENTER rack).
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.
