Abstract
A KVM switch includes a storing portion that stores partial data of a freeze-up screen outputted when each server freezes up, and a controlling portion that receives digital data (that is, screen data) transmitted from each server, determines whether received screen data includes a part identical to the partial data of the freeze-up screen, and controls a power supply regulator to restart the freeze-up server when it is determined that the received screen data includes the part identical to the partial data of the freeze-up screen.
Claims7
A KVM switch, which is connected to a power supply regulator that controls an information processing device and power supply thereto, the KVM switch comprising:
- a receiving part that receives screen data outputted from the information processing device;
- a storing part that stores partial data of a freeze-up screen outputted when the information processing device freezes up;
- a determining part that determines whether the received screen data includes a part identical to the partial data of the freeze-up screen;
- and
- a controlling part that controls the power supply regulator to restart the information processing device, when the determining part determines that the received screen data includes the part identical to the partial data of the freeze-up screen.
A KVM system comprising a KVM switch, a power supply regulator, and a power control part,
- the KVM switch including:
- a receiving part that receives screen data outputted from an information processing device;
- a first storing part that stores partial data of a freeze-up screen outputted when the information processing device freezes up;
- a determining part that determines whether the received screen data includes a part identical to the partial data of the freeze-up screen;
- and
- a transmitting part that transmits a command for turning off power supply to the information processing device to the power supply regulator when the determining part determines that the received screen data includes the part identical to the partial data of the freeze-up screen, and transmits a command for turning on power to the information processing device to the power supply regulator after a predetermined time,
- the power supply regulator having:
- a power supplying part that supplies power to the information processing device;
- and
- a controlling part that controls the power supply part to stop power supply to the information processing device based on the command for turning off power to the information processing device;
- and controls the power supply part to activate power supply to the information processing device based on the command for turning on power to the information processing device.
A computer readable medium, which stores a program that causes a KVM switch that is connected to a power supply regulator that controls an information processing device and a power supply thereto and is equipped with a storing part that stores partial data of a freeze-up screen outputted when the information processing device freezes up to function as:
- a receiving part that receives screen data outputted from the information processing device;
- a determining part that determines whether the received screen data includes a part identical to the partial data of the freeze-up screen;
- and
- a controlling part that controls a power supply regulator to restart the information processing device, when the determining part determines that the received screen data includes the part identical to the partial data of the freeze-up screen.
