Environmental
The following specifications are for the 6U PowerPC 7448 Multicomputer for standard commercial environments. Mercury also offers the RACE++ Series PowerPC 7448 in various rugged environments.

For 1.06-GHz and 1.267-GHz
Temperature
    Operating: 0°C to +40°C
    Storage: -40°C to +85°C
Minimum airflow: 12 CFM (512 MB per CN)
Operating altitude: 0-10,000 ft***
Humidity: 10 to 90% (non-condensing)
Vibration
    Random: 0.003g2/Hz, 20-2000 Hz, 1 hr/axis
    Shock: z-axis: 20g, x+y axes: 32g, 11 ms, half-sine pulse

* Requires 5-row connectors and VITA 1.7-compliant (2 amp/pin) VME backplanes.
** The 1.06-GHz product consumes approximately 2W less than the 800 MHz/7447 version of the product in a comparable configuration.
*** Contact Mercury for operating altitude above 10,000 ft.

As altitude increases, air density decreases, hence the cooling effect of a particular airflow rating decreases. Many manufacturers specify altitude and temperature ranges that are not simultaneous. Note that the above operating temperature is specified simultaneously with an altitude. Different limits can be achieved by trading among altitude, temperature, performance, and airflow. Contact Mercury for more information.
