Chapter 2 Hardware Installation
2.1 Installation Notice
To ensure the proper operation of DG-GS4200 series and your physical security,
please read carefully the following installation guide.
2.1.1 Environmental Requirements
The switch must be installed in a clean area. Otherwise, the switch may be damaged
by electrostatic adherence.
Maintain the temperature and the humidity within the set environment.
The switch must be put in a dry and cool place. Leave sufficient spacing around the
switch for good air circulation.
The switch must work in the right range of power input.
The switch must be well grounded in order to avoid ESD damage and physical injury
of people.
The switch should avoid the sunlight perpendicular incidence. Keep the switch away
from heat sources and strong electromagnetic interference sources.
The switch must be mounted to a standard 19’’ rack or placed on a clean level
desktop.
2.1.1.1 Dust and Particles
Dust is harmful to the safe operation of switch. Dust can lead to electrostatic
adherence, especially likely under low relative humidity, causing poor contact of metal
connectors or contacts. Electrostatic adherence will result in not only reduced product
lifespan, but also increased chance of communication failures. The recommended value
for dust content and particle diameter in the site is shown below:

Table 2-1 Environmental Requirements: Dust content

In addition, salt, acid and sulfide in the air are also harmful to the switch. Such
harmful gases will aggravate metal corrosion and the aging of some parts. The site should
avoid harmful gases, such as SO2, H2S, NO2, NH3and Cl2, etc. The table below details
the threshold value.

Table 2-2 Environmental Requirements: Particles
2.1.1.2 Temperature and Humidity
The switch installation site should maintain a desirable temperature and humidity.
High-humidity conditions can cause electrical resistance degradation or even electric
leakage, degradation of mechanical properties and corrosion of internal components.
Extreme low relative humidity may cause the insulation spacer to contract, making the
fastening screw insecure. Furthermore, in dry environments, static electricity is liable to be
produced and cause harm to internal circuits. Temperature extremes can cause reduced
reliability and premature aging of insulation materials, thus reducing the switch’s working
lifespan. In the hot summer, it is recommended to use air-conditioners to cool down the
site. And the cold winter, it is recommenced to use heaters. The recommended
temperature and humidity are shown below:
Temperature:
Relative humidity

15～30°C
-10～50°C

5% ～95%
Table 2-3 Environmental Requirements: Temperature and Humidity
Caution!
A sample of ambient temperature and humidity should be taken at 1.5m above the
floor and 0.4m in front of the switch rack, with no protective panel covering the front and
rear of the rack. Short term working conditions refer to a maximum of 48 hours of
continued operation and an annual cumulative total of less than 15 days. Formidable
