Table 19 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
