Information processing apparatus and method performed thereby

A method performed by an information processing apparatus having an uninterruptible power supply (UPS), the method comprising:

• detecting a power outage;
• acquiring a plurality of first signals from a plurality of motherboards, each of the first signals indicating whether the corresponding motherboard is operating;
• acquiring a plurality of second signals from the motherboards, each of the second signals indicating whether power is to be supplied from the UPS to the corresponding motherboard during a power outage;
• and
• determining that the first signal indicating that the corresponding motherboard is operating and the second signal indicating that power is to be supplied from the UPS to the corresponding motherboard during a power outage, are acquired, and then supplying power from the UPS to the motherboards.

An information processing apparatus comprising:

• an uninterruptible power supply (UPS);
• a plurality of motherboards;
• a first circuit connected to the motherboards to receive respective first signals from the motherboards, each of the first signals indicating whether the corresponding motherboard is operating;
• a second circuit connected to the motherboards to receive respective second signals from the motherboards, each of the second signals indicating whether power is to be supplied from the UPS to the corresponding motherboard during a power outage;
• a third circuit for detecting a power outage;
• and
• a fourth circuit connected to the first through third circuits, wherein
• in response to the power outage detected by the third circuit, the fourth circuit supplies power from the UPS to the motherboards when the first and second circuits each receive from at least one of the motherboards, the first signal indicating that the corresponding motherboard is operating and the second signal indicating that power is to be supplied from the UPS to the corresponding motherboard during a power outage.
