Abstract: Provided is an automatic analyzer without necessity of manual air vent in a pump. This automatic analyzer comprises a water supply tank, a supply path connected to each mechanism of an automatic analyzer from the water supply tank, a water supply pump which supplies water to each mechanism from the water supply tank through the supply path, a detector which detects abnormality in the supply path, a waste liquid path branched from the supply path in a branch pipe provided in the supply path, a relief valve provided in the waste liquid path, and a control unit which controls the operation of each mechanism in the automatic analyzer, in which the control unit opens the relief valve while driving the water supply pump, based on the abnormality in the supply path detected by the detector.

Abstract: In a network element management method and apparatus, and a network management system where mounting positions of physical components on a network element are unfixed, an external input mounting schedule for a physical component detachable from a network element as mounting plan information including a type of the physical component, a scheduled mounting position within the network element, and a scheduled mounting term is received through a graphical user interface. No overlap with a preliminarily provided mounting schedule for another physical component per each predetermined measure of the scheduled mounting position is confirmed based on the inputted mounting plan information. The mounting plan information is determined to be implementable only when all of the predetermined measures of the scheduled mounting position are confirmed.
