4.2Power Supply Requirements

(1)Allowable input voltage and current

The power supply input voltage measured at the power supply connector pin of the IDD (receiving end) must satisfy the requirement given in Subsection 2.1.3. (For other requirements, see Items (4) and (5) below.)

(2)Current waveform (reference)

Figure 4.9 shows the waveform of +12 VDC.

(3)Power on/off sequence

a)The order of the power on/off sequence of +5 VDC and +12 VDC, supplied to the IDD, does not matter.

(4)Sequential starting of spindle motors

After power is turned on to the IDD, a large amount of current flows in the +12 VDC line when the spindle motor rotation starts. Therefore, if more than one IDD is used, the spindle motors should be started sequentially using one of the following procedures to prevent overload of the power supply unit. For how to set a spindle motor start control mode, see Subsection 5.3.2.

a)Issue START/STOP UNIT command at 20-second intervals to start the spindle motors. For details of this command specification, refer to SCSI Logical Interface Specifications.

For details of this command, see "Chapter 4 Command Specification" of the Fibre Channel Interface Specification.

b)Turn on the +12 VDC power in the power supply unit at 20-second intervals to start the spindle motors sequentially.
