Industrial Ethernet switch low temperature -40℃ test

With the arrival of winter, heavy snow covers the vast land, which not only brings poetic beauty to people's lives, but also brings severe challenges to industrial production and equipment operation. In order to ensure the reliability and stability of the equipment in extreme environments, we have conducted strict low-temperature tests of -40℃ on 2 optical 8 electrical (SFP) and 2 optical 8 electrical (1x9) industrial Ethernet switches.

This test uses a professional environmental simulation device, a cryogenic box, and is conducted through the following steps:

• Preparation: Place the industrial Ethernet switch in the cryogenic box and ensure that all connections are normal. We paid special attention to the stability of the switch's power cord and network interface to avoid any accidental disconnection during the test.

• Temperature setting: Gradually lower the temperature of the cryogenic box to the target low temperature of -40°C and keep it stable. This process needs to be done slowly to ensure that temperature changes do not cause shock or damage to the switch.

•Performance monitoring: In a low-temperature environment, the switch is continuously tested for data exchange, including key indicators such as data transmission rate, packet loss rate, and latency, and the response time and processing capacity of the switch at different temperatures are recorded.

• Physical inspection: Observe the changes in the appearance of the switch at low temperatures and check for cracks. We also conduct a detailed inspection of the internal structure of the switch to ensure that there is no internal damage caused by temperature changes.

Recovery test: After returning the temperature to normal, test the performance of the switch again to ensure that it can return to normal working condition.

This step is to verify whether the switch can maintain its original performance and stability after experiencing extreme low temperatures.

The test results are as follows: Stable performance:

The industrial Ethernet switch showed excellent stability throughout the test. Even at an extremely low temperature of -40°C, key indicators such as data transmission rate, packet loss rate and latency remained within the normal range, with no obvious performance degradation. Intact appearance: After the low-temperature test, there were no cracks on the appearance of the switch. This shows that the material and design of the switch can well withstand the impact of the low-temperature environment. Functional recovery: When the temperature returns to normal temperature, the switch can quickly return to normal working state, and all functions are not affected. This further proves the reliability and stability of the switch under extreme temperature changes. Through this test, we can confidently say that our industrial Ethernet switches can maintain efficient and stable operation in extremely cold environments.

This not only adds more application scenarios to our products, but also provides a more reliable solution for our customers.
