10.10.1 Unit Life Span and Maintenance Period
The unit life span and maintenance periods after production ends for the disk array unit are as follows.
Parts used in the disk array unit include parts that must be replaced due to their life spans (such as
cooling fans, batteries, and disk drives).
Since life spans may be shorter than five years depending on the environment in which the disk array
unit is used, it is recommended that parts be replaced regularly. Contact your maintenance service
agent regarding replacements and life spans.

Battery
The battery life span becomes shorter when it is used in high temperatures environments.
The life span is about 5 years when used under an ambient temperature of 25 degree
celsius (77°F), but will be reduced to approximately half (about 2.5 years) at an ambient
temperature of 35 degree celsius (95°F). In addition, as backup frequency increases, the
battery life span becomes shorter. The life span above is calculated considering accidental
power disconnection such as power outage.
