First Claim
Patent Images
1. A computer system comprising:
- at least two power supply units for providing an output-side operating voltage from at least one input-side supply voltage,at least one power-consuming component which can be operated in at least one normal operating mode with a first power consumption and can be operated in a restricted operating mode with at least one second power consumption which is lower than the first power consumption, the power-consuming component being electrically coupled to the at least two power supply units;
control means which are coupled to the at least two power supply units and to the power-consuming component and are set up to monitor the function of the at least two power supply units and to switch the power-consuming component from the normal operating mode into the restricted operating mode immediately upon failure of at least one power supply unit to reduce the power consumption of the power-consuming component; and
at least, one management component which is coupled to the control means and is set up to detect a fault state when at least one power supply component fails and to subsequently change a configuration of the computer system upon detecting the fault state in order to reduce a power consumption of the computer system.

Abstract
A computer system includes at least two power supply units providing an output-side operating voltage from at least one input-side supply voltage, at least one power-consuming component operated in at least one normal operating mode with a first power consumption and operated in a restricted operating mode with at least one second power consumption lower than the first power consumption, the power-consuming component electrically coupled to the at least two power supply units; a controller coupled to the at least two power supply units and the power-consuming component; and at least one management component coupled to the controller.

13. A method for controlling a computer system having a power-consuming component and at least two power supply units for providing an operating voltage for the power-consuming component, said method comprising:
-
monitoring, by at least one monitoring apparatus, the at least two power supply units for a failure; generating, by the at least one monitoring apparatus, a predetermined control signal, if a failure of at least one power supply unit has been detected; if the predetermined control signal has been detected, immediately switching the power-consuming component from a normal operating, mode with a first power consumption into a restricted operating mode with a second, lower power consumption in order to effect a reduction in power consumption; and subsequently changing a configuration of the computer system, if the predetermined control signal has been detected. - View Dependent Claims (14, 15, 16, 17)

18. A method for controlling a computer system having a power-consuming component and at least two power supply units for providing an operating voltage for the power-consuming component, said method comprising:
-
monitoring the at least two power supply units for a failure; generating a predetermined control signal, if a failure of at least one power supply unit has been detected; if the predetermined control signal has been detected, immediately switching the power-consuming component from a normal operating mode with a first power consumption into a restricted operating mode with a second, lower power consumption, and subsequently changing a configuration of the computer system. - View Dependent Claims (19, 20)
