If power supply unit redundancy is selected (n+1 or n+m), the maximum standard output power available for
the system unit is reduced, but every redundant power supply unit increases the reliability and availability of
this output power level because 1 or m power supply unit(s) can fail without operations being interrupted.
Two power supply units are required for the smallest redundant PSU configuration in a BX900 system unit.
Possible values: No Redundancy, 2+1, 3+1, 4+1, 5+1, 2+2, 3+3.
