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 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 where the device is handled and it is recommended that the  
body of the handler be grounded.  
C141-F029-01EN  
1 - 3  
·
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 (about 30 seconds).  
d. Packaging  
a) Place the device in an antistatic vinyl bag along with a desiccant (silica gel).  
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 in  
Product Manual.  
1 - 4  
C141-F029-01EN  
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 in 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.

1.2  
Operation Confirmation  
Operation test  
1.2.1  
When the host computer is processing data, the disk drive monitors disk drive operation errors  
including data, command, and seek errors. The host is notified of the error that the disk drive  
detected and the user is notified of its result.  
The user may notice intermittent and indefinite failures such as overlong execution time,  
abnormal noise, abnormal odor, or failures in particular processes.  
The failure reported in the operation test will need further investigation. To ascertain the cause  
of the disk drive failure reported, the disk drive can be replaced. Failures in the operation test  
are often not caused by the host system. For example, not having enough power supply  
reserve, a loose cable connection, no timing and mechanical reserves, or relationship with  
other systems.  
In normal operation, the disk drive itself or the host determines the processing (return or halt)  
following the detected failure state.  
C141-F029-01EN  
1 - 9  
To troubleshoot the failure reported in the test at this level, accurately reproduce the condition  
that caused the failure. Then, by replacing the disk drive, try to separate the fault from the  
other sections of the disk drive host system.  
1.2.2  
Diagnostic test  
The diagnostic test is used to separate a confirmed disk drive failure to a disk drive  
subassembly or to check the disk drive performance. A test of this level usually includes a  
specific disk drive function or concentrated execution of a group of functions. The test is  
usually performed by a factory engineer and not where the failure was reported. The disk  
drive is tested using another host computer or test equipment.  
To troubleshoot the disk drive failure in the diagnostic test, the engineer will reproduce the  
failure condition. The engineer then isolates the failure to a subassembly or part of the disk  
drive.  
The procedures used in a test of this level great depend on the test equipment used. It is  
beyond the range of this manual.  
1.3  
Troubleshooting Procedure  
Troubleshooting procedure  
1.3.1  
This section describes the troubleshooting procedures for a disk drive failure at field  
maintenance level described in Subsection 1.1.3.  
In this section, troubleshooting is made to isolate the reported failure to the disk drive or a host  
system. Usually, troubleshooting is necessary only when a cause of failure is uncertain or  
unknown. When a cause of failure is clear (for example, abnormal sound in the DE or burnt  
parts on the PCA), a level of troubleshooting is low.  
1.3.2  
Troubleshooting disk drive replaced in field  
It is recommended that the whole drive be replaced in maintenance of this level. If replacing  
the drive corrects the fault, return the old drive to the factory for testing and repair. If the new  
drive shows the same fault as the one that was removed, the failure is elsewhere in the system.  
System level troubleshooting, shown in Table 1.3, is performed at the user site to isolate the  
reported failure to the disk drive or system.

C141-F029-01EN  
Table 1.3 System level and field troubleshooting  
Check to be made  
DC power cable  
Recommended work  
Confirm that the power cable is properly connected at the disk drive and  
power supply section.  
DC power voltage  
level  
Confirm that the DC power voltage is within ±5% (+5 VDC) or ±8% (+12  
VDC) of the standard value.  
When measured at pins 3 and 4 of the power supply connector, the +5 VDC  
must be 4.75 to 5.25 VDC.  
When measured at pins 1 and 2 of the disk drive power supply connector the  
+12 VDC must be 11.04 to 12.96 VDC.  
DC power ripple  
noise  
Check that the maximum ripple at +5 and +12 VDC power is less than  
100 mV peak to peak and 200 mV peak to peak respectively.  
Interface cable  
connection  
Confirm that the AT interface cable is properly connected at the disk drive  
and control unit.  
Switch setting  
Confirm that the switch on the switch on the disk drive control PCA is set  
for normal operation with the host computer. Refer to Section 3.4 in Product  
Manual for switching setting.  
System cable  
Confirm that all cable connections throughout the system correctly  
connected.  
System diagnostic  
test  
To further isolate the failure, if it can be done, execute the system level  
diagnostic routine described in the host computer manual.  
Intermittent or  
indefinite error  
Check the AC voltage level at the power supply section and recheck the DC  
voltage level at the disk drive power supply connector.  
If the AC voltage level is abnormal, or if there is a lot of electrical noise,  
notify the user.  
If the DC voltage level is unstable, replace the power supply section.  
If possible, replace the disk drive. If the fault remains, the disk drive is not  
the case. For suggestions to isolate the failure further, refer to the hardware  
and software manuals provided with the system.  
C141-F029-01EN  
1 - 11  
1.3.3  
Troubleshooting at factory  
When the trouble is recovered by replacing the drive at field (Subsection 1.3.2), troubleshoot  
the replaced drive to isolate the trouble to the subassembly parts.  
To shorten the troubleshooting time and repairing time, gather the data, such as environmental  
data and other information, from the user and then return the failed drive to the factory with  
the media defect list to repair.  
At the factory, user environment is made and a reappearance test is performed. To  
reappearance a same trouble at user, the failed drive is connected to the host system. If no  
trouble occurs by the normal test, the reappearance test is performed by adding the  
voltage/temperature load using a disk drive tester or tools according to the user environment.  
When a trouble reappeared, troubleshoot the cause of failure. Then, replace the failed unit or  
parts.  
As this level maintenance is made by a factory, this maintenance level is beyond the scope of  
this manual.  
The disk enclosure must never to opened in the field. Opening the  
disk enclosure may cause irreparable damage.

This chapter explains the procedure for removing and replacing the disk drive. It is assumed that the  
reader has a thorough knowledge of replacing the complete disk drive and replacing the power-  
interface cable.  
When carrying out these procedures, note the following items.  
·
·
·
The disk drive must have been removed from the host system.  
A power-interface cable to the disk drive must be disconnected.  
Mounting is done by reversing the steps for removal.  
To carry out maintenance properly, observe the following:  
·
·
·
·
Place removed screws and other parts where they will not get lost or damaged.  
Keep a record of all maintenance work.  
Tighten screws securely but not excessively.  
Before touching the PCA, perform the human body grounding to discharge any static electricity  
from your body. This ensures that the worker will not electrically damage the PCA.

Disk Drive Removal  
The method and procedures to dismount the disk drive to check the jumper terminal, change  
the jumper position, or replace the device differ depend on the system cabinet structure.  
Therefore, for actual working procedures, the specific conditions necessary for each system  
must be determined. The general removal procedures, with notes, is as follows.  
a) Disconnect the power-interface cable.  
b) Remove the screws that attach the drive and remove the drive from the system cabinet.  
c) When storing or transporting the drive, pack it an antistatic bag.  
Note:  
To protect the device from damage and prevent the worker getting hurt, observe the parts  
in Subsection 1.1.1 on Danger and Warnings.  
1. Perform any removal after the system power is completely  
disconnected. The cable must not be disconnected and the  
screws that attach the drive must not be removed with the power  
ON.  
2. Do not move the drive until it comes to a complete stop (about  
30 seconds after the power is turned OFF).  
3. Perform the human body grounding to discharge any static  
electricity from your body.
