Installation

The Active LED goes off while the HDD command is being executed. For some commands, however, since the Active LED goes off for only a fraction of a second, the Active LED looks like it flashes or remains lit.

5.4.2Checking connection

When the initial operation is checked normally after power is turned on, check that the HDD is connected to the loop from the host system. Although checking the connection depends on the structure of the host system, this section describes the general procedures.

(1)Checking procedure

Issuing the commands and determining the end status depends on the start mode of the spindle motor and UNIT ATTENTION report mode (specified with setting terminal). Figure 5.1 shows the recommended checking procedure for the mode that the motor starts when power is turned on. Figure 5.2 shows for the mode that the motor starts by the START/STOP command. In these recommended checking procedures, following items are checked.

Note:

Following steps a) to d) correspond to a) to d) in Figures 5.1 and 5.2.

a)Issue the TEST UNIT READY command and check that the HDD is connected correctly to the loop and the initial operation after power is turned on ended normally. The command issue period of the TEST UNIT READY command shall be more than 20 ms.

b)To control starting of the spindle motor from the host system, issue the START/STOP UNIT command to start the spindle motor.

c)Check the loop operations with the WRITE BUFFER and READ BUFFER commands.

d)Start the HDD self-diagnostic test with the SEND DIAGNOSTIC command and check the basic operations of the controller and disk drive.
