Two contributors of electronic console failures are heat and vibration. To combat some of their effects, what should be included in performing preventive maintenance procedures?
• Effects of heat and vibration on electronic equipment reliability • Role of preventive maintenance in keeping cooling/ventilation systems effective • Risks of frequent handling or disturbing electronic circuit cards and hardware
• Which option reduces heat buildup continuously without frequently disturbing electronic components? • Which actions, if done daily, might actually increase the chance of failure rather than prevent it? • Think about how most electronic consoles in industry are kept cool and clean over the long term—what is routinely maintained?
• Identify which choice addresses airflow and cooling paths rather than moving electronics around • Eliminate any choice that involves unnecessary daily removal or reseating of circuit cards • Consider standard practice: what part of a cooling system is normally cleaned or changed on a schedule?
