Normal force acting on a body is the reaction contact force which acts when there is some action force. The normal reaction force should be equal to the weight of the rod. The weight of the rod acts downward. In the given situation, the normal is not operating at a single point, but it is operating at two points of the stick that are in contact with the stairs.
