• The system automatically combines the six power supply modules as a single one.
• To enable the hot-swap feature (redundant mode), keep the total power consumption
of the system under the maximum output power of an individual power supply module.
• Always use PSUs with the same wattage and power rating. Combining PSUs with
different wattages may yield unstable results and potential damage to your system.
• At least three working power supply units are required in order for the system to boot
normally.
• The server rack or external power supply system must supply 200-220V with at least
60A at 50-60Hz. If connected to a power outlet, each power outlet must individually
supply at least 16A.
• For a steady power input, use only the power cables that come with the server system
package.
