Question 50Electricity & Electronics - 1st Asst/Chief

The correct answer is D) Periodically checking the connections between devices and components. In areas of high vibration, such as ships or other marine environments, the connections between network devices and their components are more susceptible to becoming loose or damaged. Regularly checking these connections and tightening them as needed is a recommended maintenance procedure to ensure the network equipment continues to function reliably. The other options, while potentially useful in some situations, are not the primary maintenance concern for equipment in high vibration areas. Cleaning or replacing air filters (A) and blowing out enclosures (C) address environmental factors, while testing network connections (B) is more for troubleshooting purposes rather than preventative maintenance.
