Learn how the chassis uses post-shutdown fan operation to protect internal components from residual heat. Recognize expected behavior and follow power handling precautions.

The PXIe-1081 uses active fan control to manage internal temperature. After shutdown, the fans may continue operating briefly to remove residual heat. This cooling behavior is part of the thermal protection strategy for the chassis. Completing the cooling cycle helps protect internal components and supports long-term reliability.
Note After powering off the chassis, the fans may continue running briefly to remove residual heat. This behavior supports thermal protection and helps safeguard internal components.
Notice Do not disconnect AC power immediately after shutdown. Premature power removal may interrupt the cooling cycle and reduce component lifespan.
