Table A-14 shows the wattage output possible with the 4200W power supply in
redundant mode. In redundant mode, both power supplies must have identical
inputs and all inputs must be at the same voltage. If the input voltages are
mismatched, choose the value matching the weaker of the two power supplies.
Table A-15 shows the wattage output possible with the 4200W power supply in
conbined mode.
