Device labs running 24/7 QA workloads need engineered power and cooling — not consumer-grade chargers stacked on shelves.
Power distribution - Size PSUs for peak load when all nodes run simultaneously - Use centralized rails with OVP/OCP protection - Plan dedicated circuits for rack deployments above 2–3 chassis
Cooling layout - Front-to-rear ducted airflow reduces hot spots - Ambient temperature above 30°C may require supplemental fan kits - Monitor thermal throttling during burn-in before production use
Pre-shipment testing Factory burn-in under load catches weak PSU rails and fan failures before export.
