Electromagnetic Susceptibility
The operation of your switch can be affected by external interferences, such as conducted emission by
capacitance 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 a
protection earth (PE) to effectively filter interference from the power grid.
z
Keep the device far away from radio transmitting stations, radar stations, and high-frequency
devices.
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-voltage
or over-current caused by lightning strikes.
Laser Safety
The S5820X series are Class 1 laser devices.
When an optional interface module or SFP/SFP+ module on the S5820X series is operating, do not
stare into the optical port because the laser light emitted from the optical fiber may hurt your eyes.
