The previous life spans are the average values concluded based on the test
data in a lab and the theoretical model, rather than the actual values. They
are for reference only. The actual life span must be determined based on
the environment conditions of a specific area. In addition, the previous life
spans do not indicate that a fan tray assembly becomes unavailable
immediately at the end of its life span. They are used to prompt users to
