Installation Requirements
4.2Power Supply Requirements
(1)Allowable input voltage and current
The power supply input voltage measured at the power supply connector pin of the HDDs (receiving end) must satisfy the requirement given in Subsection 2.1.3. (For other requirements, see Items (4) below.)
(2)Current waveform (reference)
Figure 4.6 shows the spin-up current waveform of +5V DC and +12V DC.
