2-3Electromagnetic SusceptibilityThe operation of your switch can be affected by external interferences, such as conducted emission bycapacitance coupling, inductance coupling, electromagnetic wave radiation, and common impedance(including the grounding system) coupling, and leads (power cables, signaling cables and output wires).To eliminate the interferences, pay attention to the following:z As the AC power system is a TN system, use a single-phase three-wire power socket with aprotection earth (PE) to effectively filter interference from the power grid.z Keep the device far away from radio transmitting stations, radar stations, and high-frequencydevices.z Use electromagnetic shielding, for example, shielded interface cables, when necessary.z Route interface cables only indoors to prevent signal ports from getting damaged by over-voltageor over-current caused by lightning strikes.Laser SafetyThe S5820X series are Class 1 laser devices.When an optional interface module or SFP/SFP+ module on the S5820X series is operating, do notstare into the optical port because the laser light emitted from the optical fiber may hurt your eyes.Installation Toolsz Flat-blade screwdriverz Phillips screwdriverz ESD-preventive wrist strapThe installation tools are not shipped with the S5820X series.
