SM3100-28TC-AC makes a lot of consideration in anti-static, but static electricity over a
certain tolerance limit will disruptive the circuit even the whole switch.
In the network connected by the switch, electrostatic induction is mainly from two aspects:
the outdoor high-voltage power lines, lightning and other external electric field; indoor
environment, flooring materials, the whole structure of the internal system. In order to
prevent electrostatic damage, we should:
Equipment and floor ground connection;
Anti-Indoor dust;
Maintain proper temperature and humidity conditions;
When touch the circuit board, user should wear anti-static wrist strap and overalls;
The demolition of the circuit board face up on an anti-static working surface or an
anti-static bag;
Avoid direct touching circuit components.

Switch may receive the jamming from exterior system. This jamming influences devices
through capacitance coupling, inductance coupling, electromagnetic wave radiation,
common impedance (including grounding system) coupling, and conducting wire (power
wire, cable and outputting wire). Pay attention to the followings:
