When two identical power supplies are installed, the power supply configuration is redundant. In redundant mode, power is supplied to the system equally from both power supplies to maximize efficiency.
When one power supply module is removed or has failed, the power supply configuration is non-redundant. Power is supplied to the system only by a single power supply module.
