Meanwhile, we recommend you to take the following measures to suppress
interfering signals:
•
Take effective measures against power grid interference to the power supply
system.
•
Keep away from electrical equipment such as medical magnetic resonance
device, helium arc welder, radio frequency electric heater, etc.
•
Try to avoid the impact of nearby areas with high power emissions (broadcast,
radar, mobile communication transmitters), electrified railways, industrial
radiation, substations, and high-voltage transmission lines.
•
The interference effect of other equipment in the server room must comply with
relevant standards and regulations.
•
Take measures to shield and isolate natural noise such as atmospheric noise
and solar radio noise when necessary.
To avoid damage to the system, take ESD protection measures. For more
information on electrostatic protection methods, refer to

As per the requirements of Appendix F.5 of IEC62368, the server is pasted with
safety protection logos. The logos and interpretations are as follows:
