Abstract

An information processing apparatus connectable to a UPS, includes motherboards, a first circuit connected to the motherboards to receive first signals therefrom, each first signal indicating whether the corresponding motherboard is operating, a second circuit connected to the motherboards to receive second signals therefrom, each second signal 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. In response to the outage, the fourth circuit supplies power from the UPS to the motherboards when the first and second circuits each receive from at least one motherboard, 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.
