The Etasis IFRP‑352NI is a 350 W redundant power supply module designed for industrial servers and control systems such as the Inspur AS500 chassis. Common failure points for this class of units include degraded capacitors, overheating due to inadequate ventilation, and failure of the internal fan or voltage regulator ICs. Begin by verifying that the input mains (240 V AC) is within spec and measuring the output rails; check for any visible signs of burn marks, swollen electrolytics, or loose connections. If the supply passes basic electrical checks, inspect the thermal interface and ensure the cooling fan is operational, then review any error logs from the host system for power‑related fault codes.[oss-gpt-20b]
