NF8460M3: Dust-Blocked Front Mesh Can Cause Shutdowns
Symptom
The source describes NF8460M3 and similar servers with excessive dust on the front bezel mesh, restricting airflow and leading to intermittent automatic shutdowns.
Checks
Check for unusually hot air at the rear exhaust. The case compared fan speed and exhaust temperature with the front cover removed and inspected the mesh against light to identify dust blockage. Avoid touching hot surfaces or rotating parts, and follow the model’s service procedure when removing the cover.

Resolution
Clean the dust from the front mesh and schedule further cleaning according to the site’s dust conditions. The photograph illustrates the source’s blocked mesh; it contains no text requiring translation.
