Abstract

The invention broadly contemplates a safety arrangement that transitions a moving component, for example a cooling fan housed within a chassis of an electronic device, between a first operating mode or condition and a second operating mode or condition. The first operating mode is a normal operating mode, allowing the component (fan) to operate (rotate) at full speed. The second operating mode is a safety or service mode, allowing the component (fan) to operate (rotate) at a reduced speed such that it is compliant with applicable safety regulations.
