5.4Confirming Operations after Installation and Preparation for Use

5.4.1Confirming initial operations

This section describes the operation check procedures after power is turned on. Since the initial operation of the IDD depends on the setting of the motor start mode, check the initial operation by either of the following procedures.

(1)Initial operation in the case of setting so that motor starts at powering-on

a)When power is turned on, the IDD executes initial self-diagnosis.

b)If an error is detected in initial self-diagnosis, the Fault LED lights up.

Remark:

The spindle motor may or may not start rotating in this stage.

c)When the IDD status is idle, the Active LED remains off (the LED lights up when the initiator accesses the IDD).

(2)Initial operation in the case of setting so that motor starts with START/STOP UNIT command

a)When power is turned on, the IDD executes initial self-diagnosis.

b)If an error is detected in initial self-diagnosis, the Fault LED lights up.

c)The spindle motor does not start rotating until the START/STOP UNIT command for the start is issued. The INIT needs to issue the START/STOP UNIT command to start the spindle motor by the procedure in Subsection 5.6.2.

d)The disk drive enters the READY status in 30 seconds after the START/STOP UNIT command is issued. At this time, the IDD reads "system information" from the system space on the disk.

e)The active LED blinks during command execution.

(3)Check items at illegal operation

a)Check that IDD are mounted correctly.

b)Check that power and voltages are supplied correctly (measure them with the IDD power connection position).

c)When the Fault LED continues lighting up, indicates that an error is detected in initial self- diagnosis. In this case, it is recommended to issue the REQUEST SENSE command from the initiator (host system) to obtain information (sense data) for error analysis.
