Technical Reference 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 The ATX form factor specification Refer to Section 1.5, page 19 2.12 Thermal Considerations CAUTION Ensure that the ambient temperature does not exceed the board's maximum operating temperature. Failure to do so 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. CAUTION Ensure that proper airflow is maintained in the processor voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. The processor voltage regulator area (item A in Figure 23) can reach a temperature of up to 85 oC in an open chassis. 85

2.12 Thermal Considerations
CAUTION
Ensure that the ambient temperature does not exceed the board
’
s maximum operating temperature.
Failure to do so 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.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit.
Failure to do
so may result in damage to the voltage regulator circuit.
The processor voltage regulator area
(item A in Figure 23) can reach a temperature of up to 85
o
C in an open chassis.
