DISCLAIMER

Failure of the MAH series and MAJ series intelligent disk drive is defined as a failure requiring

adjustments, repairs, or replacement. Fujitsu is not responsible for drive failures caused by misuse by the

user, poor environmental conditions, power trouble, host problems, cable failures, or any failure not caused

by the drive itself.

The suffix of the model name of the disk drive varies depending on the electrical requirements, capacity,

and data format at factory shipment of the SCSI, i.e., the interface for connecting the three device types or

host system and the disk drives (Note 1). However, in this manual, the typical model names (Note 2) are

used unless otherwise noted. These disk drives may be called intelligent disk drives (IDD), drives, or

devices in this manual.

Important Alert Items

Important Alert Messages

The important alert messages in this manual are as follows:

A hazardous situation could result in minor or moderate personal injury if the

user does not perform the procedure correctly. This alert signal also indicates

that damages to the product or other property may occur if the user does not

perform the procedure correctly.

Task Alert message Page

Mounting Installation For MAH and MAJ series, Reed Solomon codes are applied for

their ECC.

The sector-data is divided into 4 interleaving sectors, and ECC is

performed in each sector where the maximum number of errors (up

to 5 byte) can be corrected. [Total maximum byte: 5 byte x 4 (

interleave) = 20 byte]

If the error of read sector keeps allowable error byte number,

correction is performed.

However, if error byte exceeds its allowable number, correction

may not be performed properly.

Data loss

1. The user must not change the setting of terminals not described

in this section. Do not change setting status set at factory

shipment.

2. Do not change the setting of terminals except following setting

pins during the power is turned on.

• Write protect: CN2 9-10

3. To short the setting terminal, use the short plug attached when

the device is shipped from the factory.

Damage

1. Check that system power is off before connecting or

disconnecting cables.

2. Do not connect or disconnect cables when power is on.

Damage

1. Be careful of the insertion directions of the SCSI connectors.

With the system in which terminating resistor power is supplied

via the SCSI cable, if the power is turned on, the overcurrent

protection fuse of the terminating resistor power supplier may

be blown or the cable may be burnt if overcurrent protection is

not provided.

When the recommended parts listed in Table 4.2 are used,

inserting the cables in the wrong direction can be prevented.

Task Alert message Page

Mounting Installation 2. To connect SCSI devices, be careful of the connection position

of the cable. Check that the SCSI device with the terminating

resistor is the last device connected to the cable.

Data loss

When the SEND DIAGNOSTIC command terminates with the

CHECK CONDITION status, the INIT must collect the error

information using the REQUEST SENSE command. The

RECEIVE DIAGNOSTIC RESULTS command cannot read out

the error information detected in the self-diagnostics.

Caution

1. To avoid shocks, turn off the power before mounting or

removing a PCA, and before connecting or disconnecting a

cable, connector, or plug.

2. To avoid injury, do not touch the mechanical assembly during

disk drive operation.

3. Do not use solvents to clean the disk drive.

Caution

1. Always ground yourself with a wrist strap connected to ground

before handling. ESD (Electrostatics Discharge) may cause

the damage to the device.

2. To prevent electrical damage to the disk drive, turn the power

off before mounting or removing a PCA or connecting or

disconnecting a cable, connector, or plug.

3. Do not turn the power on while removing a PCA. This

operation is required to prevent unexpected or unpredictable

operation.

4. Do not use a conductive cleaner to clean a disk drive assembly.

5. Open all ventilation holes to prevent overheating of electric

circuits.

6. Ribbon cables are marked with a colored line. Connect the

ribbon cable to a cable connector with the colored wire

connected to pin 1.

Damage

Do not open the DE in the field because it is completely sealed.

Data loss

Save data stored on the disk drive before requesting repair. Fujitsu

does not assume responsibility if data is destroyed during servicing

or repair.

Caution

Never open the disk enclosure in the field. Opening the disk

enclosure in the field may cause an irreparable fault.
