2.11.5 Power Supply Considerations
CAUTION
The 5-V standby line for the power supply must be capable of providing adequate +5 V standby
current. Failure to do so can damage the power supply. The total amount of standby current
required depends on the wake devices supported and manufacturing options. Refer to
Section 2.11.3 on page 78 for additional information.
System integrators should refer to the power usage values listed in Section 2.11.1, on page 77
when selecting a power supply for use with the D815EEA board.
Measurements account only for current sourced by the D815EEA board while running in idle
modes of the started operating systems.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the following recommendations found in the indicated
sections of the ATX form factor specification.
• The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2)
• The current capability of the +5 VSB line (Section 4.2.1.2)
• All timing parameters (Section 4.2.1.3)
• All voltage tolerances (Section 4.2.2)
For information about Refer to
The ATX form factor specification Section 1.3, page 16
2.12 Thermal Considerations
CAUTION
An ambient temperature that exceeds the board’s maximum operating temperature by 5
o
C to 10
o
C
could cause components to exceed their maximum case temperature and malfunction. For
information about the maximum operating temperature, see the environmental specifications in
Section 2.14.
