1.5.1 Hardware Reliability Design
I. De-rating design
To improve system reliability and prolong the service life of components, components
are carefully selected and strictly tested, and less stress (electrical stress and
temperature stress) is to be borne in actual operation than its designed rating.
II. Selection and control of component
The category, specifications and manufacturers of the components are carefully
selected and reviewed according to the requirements of the product reliability and
maintainability. The replaceability and normalization of components is one of the main
factors for the decision, which help to reduce the types of components used and
hence improve the availability of the system.
