Maintenance levels
If a disk drive is faulty, replace the whole disk drive since repair requires special tools and
environment. This section explains the two maintenance levels.
(1)
Field maintenance (disk drive replacement)
•
This replacement is done at the user's site.

Replacement uses standard tools.

Replacement is usually done by the user, retail dealer, distributor, or OEM engineer.
(2)
Factory maintenance (parts replacement)
•
This replacement can only be done by Fujitsu.
•
Replacement includes maintenance training and OEM engineer support. OEM engineers usually
support retail dealers and distributors.
•
Replacement uses factory tools and test equipment.
