5.5Checking Operation after Installation and Preparing the IDD for Use

5.5.1Checking initial operation

This section explains how to check operation after power is turned on. Since the initial operation of an IDD differs depending on the settings of the motor start mode, check the following initial operations according to the motor start mode set during installation.

(1)Initial operation if the settings have been specified so that turning power on automatically starts rotating the motor

a)When power is turned on, the Active LED blinks and the IDD starts the initial self-diagnosis.

b)If the initial self-diagnosis detects a problem, the IDD sends the Fault LED Out signal to the interface connector, as specified by SFF8045.

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

c)If the IDD is in idle mode, the Active LED remains lit. (When the initiator accesses the IDD, the LED goes off and then goes on again at the end of the processing requested by the initiator.)

(2)Initial operation if the settings have been specified so that the START/STOP UNIT command is used to start rotating the motor

a)When power is turned on, the Active LED goes on momentarily and the IDD starts the initial self-diagnosis.

b)If the initial self-diagnosis detects a problem, the IDD sends the Fault LED Out signal to the interface connector, as specified by SFF8045.

c)The spindle motor does not rotate until the START/STOP UNIT command is received. The initiator is required to use the procedure described in Section 5.5.2 to send the START/STOP UNIT command.

d)About 60 seconds after the START/STOP UNIT command is received, the disk drive enters the READY state. The IDD then starts reading system information from the system space on disks.

e)The Active LED goes off while the command is being executed.

(3)Take the following actions if a problem occurs:

a)Check if all cables are correctly connected.

b)Check if the power supply voltage is correct. (Measure the voltage at the power connector on the IDD.)
