Risk mitigation should be considered when designing systems with high-uptime requirements, particularly those operating in rugged, remote or inaccessible areas. Operation in such conditions can make it difficult for a technician to access the repair location and/or obtain the replacement parts needed to restore service quickly. Risks to digital logic in high-uptime systems include uncontrolled voltage surges on the upstream power bus, DC/DC controller timing errors which become more critical with a high input to output voltage ratio, and the unfortunate reality that improper electronic components can enter even the most secure manufacturing line as evidenced in a US Senate Armed Services Committee report in May 2012. An unabated overvoltage fault could damage the logic device possibly resulting in smoke or even fire which could destroy evidence needed to determine the cause and corrective action.
