ABSTRACT: This work arises like a need to diminish the operation loss risk of a data harvesting station. The station collects GPS and weather information on the top of the Aconcagua Mountain located in Argentina. The access is only possible during summer season. Between April and November of each year the access to the station is impossible due to the extreme climatic conditions. Under such conditions the station should be capable of continuing its operation after to have a total loss of energy. A failure mode and effect analysis was carried out by components. Critical failure modes were identified and eliminated through the redesign. The analysis carried out was oriented by the strong influence of the environment in the behavior of each component. The correct characterization of the environment turned out to be fundamental. The design wasconcluded with a series of modifications arisen of the analysis.
