(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.
4.2 Power 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.
