Apart from dust, the switch has strict requirements for SO2, H2S, NH3,
and Cl2 in the room, because these harmful gases speed up the eroding
of metals and the aging of some components.
The specific limitations are as follows:
Gas Maximum value (mg/m3)
SO
2
0.2
H

S
0.006
NH

Anti-static
065-7434 Signamax 24-Port 10/100 L3 switch takes lots of measures in
anti-static, but when the static exceeds a certain volume, the circuits
even the whole device are damaged.
In the communication network connected to the switch, static electricity
originates from external electric field of high-pressure like electricity
cables and thunders, and internal system such as floor material and
chassis structure. To prevent the damage caused by the static, do as
follows:
 Ensure proper equipment grounding
 Maintain dustproof room
 Keep suitable temperature & humidity
 Wear anti-static equipment
 Place the disassembled circuit board on the anti static
workstation and keep the face upturned or in the anti static bag
 When viewing or removing the disassembled circuit board, touch
the edge of circuit board and avoid touching the components on
the circuit board.
Electromagnetic Environment Requirements
The various interference sources no matter from the exterior of devices
or application systems or from the interior affect the devices through
capacitance coupling, inductance coupling, electromagnetic radiation,
public impedance (including grounding system) and lead (such as power
lines, signal lines and output lines).
Therefore, pay attention to the following:
 Take anti-electric network interference for power system;
