Abstract: An information processing apparatus includes a power supply, a fan that causes air to flow into the power supply, and a power distributor that is disposed in front of or in back of the power supply in a direction of flow of the air due to the fan and that is electrically coupled to the power supply, wherein a vent through which the air passes is formed in a surface of the power distributor that faces the power supply.

Abstract: An information processing apparatus includes a substrate that includes a first connector and a second connector, a backplane that includes a third connector coupled to the first connector and a fourth connector coupled to the second connector, and a metal plate attached to the backplane, wherein the metal plate has an opening to which the fourth connector is attached, wherein the first connector is arranged near a central part of the substrate on an end side inserted into the backplane and the second connector is arranged on each side of the first connector, and wherein a clearance between the opening of the metal plate and the fourth connector increases as a distance from the third connector to the fourth connector increases.
