Why is the GS1920-24HPv2 Fan Speed Constantly High?

Question: The fan on my GS1920-24HPv2 switch is running at full speed (around 9,000 RPM) continuously, creating a loud noise. Temperatures are normal, and the Smart Fan feature is not regulating the fan speed as expected. What should I do?

Solution:

Based on the case description and technical assessment:

• The issue of fans running at full speed consistently might be caused by a hardware fault or firmware-related problem.
• Ensure the device's firmware version is up to date. If the firmware version differs from the one reporting the error, reinstall the latest firmware and capture the tech-support logs once again.
• Check the operating environment of your device for suitable conditions. For example, if the device is mounted in a cabinet, ensure proper ventilation is in place.

If the issue persists after these steps, as confirmed in this case, it seems to be a hardware malfunction. It is recommended to start an RMA (Return Merchandise Authorization) process for the device.
