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.
