1.1.2 Maintenance requirements
(1) Preventive maintenance
The disk drive needs no preventive maintenance, not even the air filter needs to be
changed.
Device damage
The DE is completely sealed. Do not open the DE in the field.
(2) Service life
In situations where management and handling are correct, the life of the disk drive
is five years when the DE surface temperature is less than 48°C. When the DE
surface temperature exceeds 48°C, the life is five years or 20,000 hours of
operation, whichever occurs first. Refer to Section 1.7 and 3.2 in Product Manual.

whole disk drive.
