APPENDIX HANDLING REPLACEABLE COMPONENTS

Do not use a replaceable component for longer than the recommended
replacement cycle. If you do, a deteriorating or worn-out component may cause
the equipment to fail.
・As you use a component, it gradually deteriorates and becomes subject to wear and tear. The
following components must be replaced at fixed intervals.
・Replacement of these components is not free of charge.
・The recommended replacement cycle in the following table assumes that the average ambient
temperature of the system unit is 25°C or less.
Note that when the average ambient temperature exceeds 25°C, the replacement cycle may be
shortened in some cases.

HDD should be replaced every four years or when the power-on
hours count exceeds 20000 hours, whichever comes first.
If a RAS feature displays a drive-failure prediction icon for a
drive, replace that drive as soon as possible because a failure
might occur in the near future.
In order to ensure quick recovery of corrupted files, routinely
back up your files.
