1 maximum temperature for reliable operation specified by the component manufacturer.

Note An MVME5100 Single Board Computer and an IPMC761 I/O board was tested in a Motorola lab environment, and it was verified that the reliability of the components would not be compromised when operating in a maximum ambient temperature of 55 degrees C, if the required airflow of 400 LFM is provided. Customer findings my differ based on specific environmental and operational characteristics.
