Installation and Maintenance Guidelines
Installation notes: The MVME2400 Series modules require a 6U VME chassis with appropriate cooling. Convection-cooled units necessitate an external fan to maintain operating temperatures within the -40°C to +85°C range. Ensure proper grounding during installation to prevent electrostatic discharge damage. Align the module’s edge connectors with the chassis backplane and secure with front-panel screws to ensure stable bus connections.
Maintenance recommendations: Periodically inspect the module for dust accumulation and verify cooling airflow. Monitor ECC memory error logs to detect potential hardware issues early. For conformal-coated variants, avoid harsh cleaning agents that may damage the coating.
