5.6Confirming Operations after Installation and Preparation for Use

5.6.1Confirming 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 LED blinks an instant and the IDD executes initial self- diagnosis.

b)If an error is detected in the initial self-diagnosis, the LED blinks periodically.

Remark:

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

c)When the IDD status is idle, the LED remains off (when the initiator accesses the IDD via the SCSI bus, the LED lights).

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

a)When power is turned on, the LED blinks an instant and the IDD executes initial self- diagnosis.

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

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 60 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 LED blinks during command execution.

(3)Check items at illegal operation

a)Check that cables are mounted correctly.

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

c)Check the setting of each setting terminal. Note that the initial operation depends on the setting of the motor start mode and LED display requirements.
