5.4 Environmental
Table 14 lists the environmental specifications for the board.
CAUTION
If the external ambient temperature exceeds 35
o
C, further thermal testing is required to ensure
components do not exceed their maximum operating temperature.

Note: The operating temperature of the board may be determined by measuring the air temperature from the junction of
the heatsink fins and fan, next to the attachment screw, in a closed chassis, while the system is in operation.
Note: Before attempting to operate this board, the overall temperature of the board must be above the minimum
operating temperature specified. It is recommended that the board temperature be at least room temperature
before attempting to power on the board. The operating and non-operating environment must avoid condensing
humidity.
