WOODWARD 5466-351 Bus interface module

Cooling Requirements The Motorola MVME188A VMEmodule board set is specified, designed, and tested to operate reliably with an incoming air temperature range from 0 degrees C to 55 degrees C (32 degrees to 131 degrees F) with forced air cooling at an inlet velocity of 300 LFM. Temperature qualification is performed in a standard Motorola VMEsystem 3000 chassis. The incoming air temperature and velocity is measured between the fan assembly and the card cage, where the incoming airstream first encounters the module under test. Test software is executed as the module is subjected to ambient temperature variations. Case temperatures of critical, high power density integrated circuits are monitored to ensure component vendors specifications are not exceeded.

While the exact amount of airflow

 required for cooling depends on the ambient air temperature and the type, number, and location of boards and other heat sources, adequate cooling can usually be achieved with 300 LFM flowing over the module. Less airflow is required to cool the module in environments having lower maximum ambients. Under more favorable thermal conditions, it may be possible to operate the module reliably at higher than 55 degrees C with increased airflow. It is important to note that there are other factors, such as the rated CFM of the air mover, which determine the actual volume and speed of air flowing over a module.

FCC Compliance 

This VMEmodule board set (MVME188A) was tested in an FCC-compliant chassis, and meets the requirements for Class A equipment. FCC compliance was achieved under the following conditions: a. Shielded cables on all external 1/0 ports. b. Cable shields connected to earth ground via metal shell connectors bonded to a conductive module front panel. c. Conductive chassis rails connected to earth ground. This provides the path for connecting shields to earth ground. d. Front panel screws properly tightened. For minimum RF emissions, it is essential that the conditions above be implemented; failure to do so could compromise the FCC compliance of the equipment containing the module.
