(6)External magnetic field

Do not install the HDDs in the vicinity of equipment giving off strong magnetic fields, such as monitors, televisions, or loudspeakers.

(7)Leak magnetic flux

Do not mount the HDDs near the devices that the leakage magnetic flux influence easily.

4.2Power Supply Requirements

(1)Allowable input voltage and current

The power supply input voltage measured at the power supply connector pin of the HDD (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 4.7 shows the spin-up current waveform of +5V DC and +12V DC.
