CHAPTER 2 DIAGNOSIS AND MAINTENANCE
2.1 Maintenance Condition
2.2 Diagnosis
2.3 Troubleshooting Method
2.4 Unit Version Number
2.1 Maintenance Conditions
The following conditions are applicable to on-site maintenance:
(1) Preventive maintenance
No preventive maintenance is required.
(2) Service life
The internal MO drive does not require and overhaul during the first five years
after installation, provided that the customer cleans the disks and optical parts, and
handles them appropriately.
(3) Service system and repair
Fujitsu has a service system and repair facility for MO drives. Customers should
submit information required for the replacement or repair of an MO drive to the
responsible person in Fujitsu. The following information is usually required:
a) Model No. of the internal MO drive, part number (P/N), unit version number,
serial number (S/N), and manufacturing date
b) Fault occurrence status
• Date of failure occurrence
• System configuration
• Environmental conditions (temperature and humidity, voltage, etc.)
c) Fault history
d) Fault details
• Failure outline
• Error messages
• Other fault analysis infor mation
C156-F046-01EN 2-1
Diagnosis and MaintenanceDiagnosis and Maintenance
2.2 Diagnosis
The MO drive has an initial self-diagnosis function, which checks the normal basic
operation of the MO drive.
•
Initial self-diagnosis function
When the power is turned on, the MO drive executes initial self-diagnosis,
which includes a basic test of hardware functions.
If an error is detected during self-diagnosis, the LED on the front panel of the
MO drive blinks. The status can be cleared by turning the power off and then
on again. When this status is cleared, the MO drive re-executes the initial
self-diagnosis.
2.3 Troubleshooting Method
The system-level troubleshooting steps listed below are performed for determining
if the fault is caused by an MO drive unit or caused by a system. The steps should
be performed by customers on-site.
Item Recommended procedure
MO cartridge Check that a recommended MO cartridge is loaded and the surface
of the disk is free from dirt or scratches.
AC adapter Check whether power indicator on the device side has lighted up
before connecting the device between host computer with the USB
cable.
Interface cable connection Check that the interface cable is correctly connected to the MO
drive.
System cable Check that all cables in the system are correctly connected.
System diagnosis test Execute the system level diagnostic routines given in the host
computer manual to further isola te the fau lt, if poss ib le.
Intermittent or indefinite error Replace the MO drive if possible. If the faulty condition continues
after the replacement, the fault wil l not be caused by the MO driv e.
Refer to the provided hardware and software manuals about the
system further, for clues of identifying cause of the failure.
2-2 C156-F046-01EN
2.4 Unit Ver sion Number
If a unit version number should be changed on site, take the following steps:
Diagnosis and Maintenance
Figure 2.1 Unit revision number label
(1) Revision-number display at shipment
The unit version number of an MO drive is indicated by crossing out unnecessary
number with an equal sign (=) in the corresponding alphanumeric character string
on the label. (See Figure 2.2.)
(2) Revision number changes in the field
When the revision number is changed following part replacement or other
modifications, the applicable level is indicated by the corresponding number
enclosed with a circle in the corresponding number string. (See Figure 2.2.)
Fujitsu issues a Change Request/Notification regarding post-factory-shipment
revision number changes. When the user changes the version number, the
revision-number label should be updated as described above after the change is
applied.

4.1 Unpacking
The following provides notes on unpacking a replacing MO disk drive:
•
Ensure flat and level working space, and pay attention to indication of upside
and downside on a package box. Avoid placing the unit directly on a firm
desk, etc. Handle a unit on a soft material such as rubber mat, etc.
4.2 Packing
•
When removing cushions, pay attention not to strain an MO disk drive.
•
When taking a unit out of an anti-static plastic bag, pay extra attention not to
strain printed circuit surface and interface connectors.
•
If an MO disk drive is moved into a place where room temperature changes
by 10 degrees Celsius, leave the unit packed for more than 2 hours after
moving, for avoiding condensation.
The following provides notes on packing a replaced MO disk drive:
•
For packing, use the same cushions and a box as those provided upon delivery
of a unit. If the same cushions and a box are unavailable, use a box with
cushions that do not give physical shock to an MO disk drive.
•
Pack an MO disk drive with an MO cartridge removed (with the carriage
locked).
•
When packing an MO disk drive, provide sufficient protection against damage
on printed circuit surface and interface connectors.
•
Put an MO disk drive into an anti-static plastic bag with desiccant.
•
Provide plainly visible signs indicating "THIS SIDE UP" and "HANDLE
WITH CARE" outside a box.
•
Other provided materials (AC adapter, cable, media, etc.) should be kept
separately. Do not pack them with an MO disk drive.
