2-41ASUS ESC4000 G4 Series• The system automatically combines the two power supply modules as a single one.The combined output power varies with input voltages. Refer to the table below fordetails.Input Voltage Max. Output Power (Watt) per PSU100V—127Vac, 12.9A, 50-60Hz 1000W200V—240Vac, 9.5A, 50-60Hz 1600W• To enable the hot-swap feature (redundant mode), keep the total power consumptionof the system under the maximum output power of an individual power supply module.• Always use PSUs with the same watt and power rating. Combining PSUs with differentwattage (e.g. 1 x 1620 W + 1 x 2000 W) may yield unstable results and potentialdamage to your system.• For a steady power input, use only the power cables that come with the server systempackage.
