2.2.3 Anti-interference Requirements

A switch in use may be affected by the interference from outside the system by way of
capacitance coupling, inductance coupling, electromagnetic radiation, public
impedance (including the grounding system) coupling or conducting line (power line,
signaling line, and transmission line). Therefore, you should pay attention to the
following:
If AC supply system is TN system, AC power socket should be a single-phase
three-line power socket with Protection Earth (PE) so that the filter circuit on the
equipment can effectively filter out the interference coming from the power supply
system.
Keep the switch far away from high-power radio transmitters, radars, and
high-frequency heavy-current devices.
Adopt electromagnetic shielding measure if necessary. For example, you can
adopt shielded interface cable.
Wire interface cables indoors. Do not wire cables outdoors in case that
over-voltage and over-current damage the device.

2.2.4 Laser Usage Security

S3100 Series Ethernet Switches are category-1 laser equipment.
Caution:
When an optional interface card of the S3100 Series Ethernet Switches is operating,
avoid staring into the optical interface because the high-energy laser beam emitted
from the optical fiber may hurt your eyes.
