Installation

Damage

 

 

1.

Be careful of the insertion orientation of the SCSI connectors. With the

5-12

 

 

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.

 

 

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.

 

Diagnostics and

Data loss

 

Maintenance

When the SEND DIAGNOSTIC command terminates with the CHECK

6-4

 

 

CONDITION status, the initiator 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 connecting or disconnecting a

6-5

 

 

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

6-6

 

 

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

 

 

 

connecting or disconnecting a cable, connector, or plug.

 

 

3.

Do not remove 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.

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

1.

Never remove any labels from the drive.

6-14

2.

Never open the disk enclosure for any reason.

 

 

Doing so will void any warranties.

 

Data loss

 

Save data stored on the disk drive to other media before requesting repair.

6-7

Fujitsu does not assume responsibility if data is destroyed during servicing

 

or repair.
