a cable or connector plug when the drive is powered.
This will prevent electrical damage to the disk drive.
3. Operating the disk drive with one or more PCA missing
will be unpredictable. Only power the drive with all
boards installed.
4. Avoid any detergent which may cause short circuits
when cleaning assemblies.
5. Keep all vents open opened and unblocked. Avoid other
conditions which may cause circuits to overheat.

1.1 Maintenance
1.1.1 Rules for maintenance
The following cautions must be observed to prevent injury during troubleshooting
or maintenance.
Static, Damage
1. Don’t install or remove a PCA or connect or disconnect a cable
or connector plug when the drive is powered. This may give
you an electric shock.
2. Keep away from mechanical assemblies in the unit during
operation. This may cause injuries.
3. Avoid dangerous detergent when the disk drive is cleaned.
The following cautions must be observed to avoid damaging the disk drive during
troubleshooting and maintenance.
Device damage
1. Before touching a PCA or the drive, wear a wrist strap and
perform the human body grounding to discharge static
electricity from your body. This will prevent irreparable
damage to the PCA and the head of the drive.
2. Don’t install or remove a PCA or connect or disconnect a cable

circumstances. Doing so may cause irreparable damage to the
cover.

1.1 Maintenance
C141-F073 1-3
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 or 30,000 hours of operation, whichever occurs first. Refer to
Section 1.7 and 3.2 in Product Manual.
(3) Exchangeable parts in field
The PCA and the DE cannot be replaced separately in the field. Replace the
whole disk drive.
(4) Service system and repair
Fujitsu Limited has a disk drive service system and repair facility. When making
a request for repair or parts replacement, you should provide related information
usually including:
a) Model name of disk drive, part number (P/N), disk drive revision number,
manufacture serial number (S/N), and date of manufacture of the disk drive
b) Circumstances when the fault occurred
− Date of trouble occurred
− System configuration
− Environmental conditions (including temperature, humidity, and voltage)
c) Fault history of the drive
d) Details of the fault
− Description of the fault
− Issued command and specified parameters
− Status (Status/Error register)
− Interval of the fault
− Other information for fault diagnosis

Data corruption
When asking for repair, save all data stored in the disk drive
beforehand. Fujitsu Limited is not responsible for any loss of data
during service and repair.
(5) Notes on handling
a. General notes
a) Vibrations and shocks more severe than allowed will cause fatal damage to
the device so be very careful. Be especially careful when unpacking the
device.
b) Do not leave the device in a dusty environment.
c) Because the device uses GMR (giant MR head) and static sensitive CMOS
semiconductors take the following precautions, be careful of the handling on
the following points after the device is unpacked.
− Use an antistatic mat, etc. in the environment for handling the equipment.
The worker should also be physically grounded (e.g., wearing a wrist
strap).
− Hold by the DE section, do not directly touch the PCA unit
unnecessarily.
b. Unpacking
a) Use a flat workplace, find which side of the pack is up and be careful not to
have the wrong side facing upwards. Do not place the device directly on a
hard table, place it on something soft such as a rubber mat.
b) Be careful not to apply any excessive force to the packed device when
removing the shock absorbing material.
c) When taking the device out of the antistatic bag, be especially careful not to
apply any excessive force to the PCA or to the interface connector section.
d) Never ever remove the DE seal label and screws and the DE cover.
c. Installation
a) When the power is ON, do not change the switch setting, or connecting, or
disconnecting connectors.
b) Do not move the device or disconnect connectors with the power ON or until
the disk drive unit comes to a complete stop after the power is turned OFF.
(It is required to wait more than 30 seconds.)
d. Packaging
a) Place the device in an antistatic vinyl bag along with a desiccant (silica gel).

1.1 Maintenance
C141-F073 1-5
b) It is recommended that you use the shock absorption cushion material and
packaging that contained the device when it was delivered by Fujitsu.
If the same packaging material cannot be used, use a shock absorbent box that
will transmit shocks directly to the device. When using this type of box,
adequately protect the PCA surface and interface connector section.
c) Place a label showing which side is up and clearly stating the notes on
handling on the outside of the packaging.
e. Delivery
a) As a rule, deliver as it is packaged and keep the up side up.
b) If delivering a single drive after it is unpacked, take it only a short distance.
Also, use shock absorbent material to protect it against shock and vibration.
Deliver an unpacked device in either of the allowable packed positions.
Refer to Section 3.2 of the MHV2080AS, MHV2060AS, MHV2040AS Disk
Drives Product Manual.
f. Storage
a) Store in dampproof packaging.
b) Take care that the environmental requirements satisfy the non-operating
environmental specifications described in Section 1.4 of the MHV2080AS,
MHV2060AS, MHV2040AS Disk Drives Product Manual.
c) To prevent condensation, do not subject the device to sudden changes of
temperature.
1.1.3 Maintenance levels
Because of its compact size and special repair requirements, it is recommended
that the whole disk drive be replaced. This section describes maintenance on two
levels.
(1) Field maintenance (disk drive replacement)
• Replacement at the user site.
• Disk drive replacement requires ordinary tools.
• Usually, the user, retailer, seller, or OEM trader will replace the drive.
(2) Factory maintenance (parts replacement)
• Only Fujitsu can perform maintenance at this level.
• This includes maintenance training and assisting other OEM traders. The
OEM trader usually assists the retailer and seller.
• Use the factory level tools and test equipment. This includes recommended
spare parts and repairing or replacing various parts.

1.1.4 Disk drive revision number
The disk drive revision number is a single alphabetic character followed by a
single alphanumeric character. It is stuck on the DE and marked on the revision
number label. Figure 1.1 shows the disk drive revision number label format.
Disk drive revision number
Firmware code/revision
Figure 1.1 Disk drive revision number label
(1) Revision number marking at delivery
The machine revision number is indicated by crossing out up to the relevant
number in the relevant alphabetic character row using = marks (see Figure 1.2).
(2) Revision number change in the field
When a part is replaced in the field or other modifications are made, the machine
revision number may need to be changed. The level is indicated by crossing out
the relevant number in the relevant alphabetic character row using ¡marks (see
Figure 1.2).
(3) Firmware code and revision
First 4-digit indicates a firmware code and rest 4-digit indicates its revision.
Note:
For a change of revision number after delivery, Fujitsu issues a
“Change Request/Notice” and the disk drive revision number after
the change. When a change is made at the user site, the revision
number level should be changed as described above.
