See Section 5.1 for notes on packing and handling when returning the disk drive.
6.2.3 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.
