CHAPTER 1 MAINTENANCE AND DIAGNOSIS Maintenance Operation Confirmation Troubleshooting Procedure This chapter describes the maintenance, diagnosis, operation check, and troubleshooting of the disk drive. The following are explained: Rules for regular maintenance and troubleshooting Display of maintenance level (field and factory) Display of machine revision number and number change in the field Tools and test devices needed for each maintenance level Standard testing for each maintenance level...
1. Before touching a PCA, perform the human body grounding to discharge static electricity from your body. This will prevent electrical damage to the PCA. 2. Don't install or remove a PCA or connect or disconnect a cable or connector plug when the drive is powered. This will prevent electrical damage to the disk drive.
Page 16
The PCA and the DE cannot be replaced separately in the field. Replace the whole disk drive. 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:...

Place the device in an antistatic vinyl bag along with a desiccant (silica gel). 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.
Usually, the user, retailer, seller, or OEM trader will replace the drive. 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.
First 2-digit indicates a firmware code and rest 2-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.
1.1.5 Tools and test equipment At the field maintenance level, only ordinary hand tools are required for troubleshooting and repairing the disk drive. Special tools and test equipment is not required. Factory level tools and test equipment are beyond the scope of this manual. 1.1.6 Self-diagnostics The disk drive has the following self-diagnostics.
Start Check the host system (Table 1.1) Operation test with the Analyze the system host computer or test System normal? related failure equipment Disk drive Test acceptable? replacement or repair Continue with the Disk drive normal? operation Diagnostic test with the host computer or test equipment Test acceptable?
Table 1.1 Status register contents Status bit Contents BIT0 = 1 Shown in Table 1.2 BIT1, 2 Normal BIT3 = 1 (1) Check whether vibration is transmitted because of the way the disk drive is mounted. BIT4 = 1 (2) Check the power, cable, and connector. BIT5 = 1 (3) If it is concluded that the disk drive is the cause, replace the disk drive.
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...
Table 1.3 System level and field troubleshooting Check to be made Recommended work DC power cable Confirm that the power cable is properly connected at the disk drive and power supply section. DC power voltage Confirm that the DC power voltage is within ±5% of the standard value. level When measured at pins 3 and 4 of the power supply connector, the +5 VDC must be 4.75 to 5.25 VDC.
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.
See Table 2.1 for the model and parts numbers to order the replacement disk drive.

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.
