Functional testing is what separates a reliable spare from a gamble. Visual inspection detects less than 30% of actual faults. The remaining 70% — signal drift, communication timeouts, intermittent failures — only surface under power. Our verification protocol for every 1794 includes power-up validation on a live rack, calibrated signal injection on all channels, communication port testing, and 48-hour thermal burn-in at 55°C.
