Core switch breakdown solution

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。

I would like to ask if there is a solution to the breakdown of core switch caused by this cleaning。

I remember you asked the same question in a previous post. As you said, the equipment has too much dust.
This situation will affect the heat dissipation of the equipment, and lead to high temperature of the board, etc. In severe cases, it will cause the LC to restart or not work, so it is recommended to clean the dust on the chassis, LC, ventilation channel and in time.

I want to know how to disassemble his air filter. The document does not mention where the air filter is located

I did not find that the 4507 has an air filter, which may not be included in the design. As long as the 4507 is found to have relatively thick dust, you can first remove the dust from the ventilation baffle or the LC, especially near the alarm slot. .
