Mar 17 13:46:56.918: %C4K_IOSMODPORTMAN-4-MODULETEMPHIGH: Module 3 Sensor VFE temperature is at or over threshold - CurrentTemp: 79C, Threshold: 79C 发动机：模块3传感器VFE温度处于或超过阈值-CurrentTemp: 79C,阈值79C

The module temperature of the CPU module is also too high

The temperature of the power module is too high

But CPU usage is also low

At present, there should be too much dust. I intend to clean up the dust. Is there any dismantling process or better solution

thank you

如果的确发现设备的板卡，挡板，尤其是进出风口比较多灰尘的话，还是先建议清灰。

这个log的建议也是找出根本的原因，鉴于没有发现其他的问题，可以先尝试清灰看看。

Error Message    C4K_IOSMODPORTMAN-4-MODULETEMPHIGH: Module [dec] Sensor [char] 
temperature is at  or over threshold - CurrentTemp: [dec]C, Threshold: [dec]C

Explanation    The module temperature is above its threshold. If the temperature goes above critical threshold, another message will be logged and the system will shut down to prevent damage to hardware.

Recommended Action    Inspect the module and find out why it is heating up.
