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:

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:

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

operation conditions refers to the ambient temperature and relative humidity value that
may occur during an air-conditioning system failure, and normal operation conditions
should be recovered within 5 hours.
2.1.1.3 Power Supply
It is adopted module switch power for the switch, the input parameters of power are
shown below:
The AC input voltage: 90~300VAC
The frequency: 47Hz ～63Hz
The DC input voltage: 12V/3.3A
Before powering on the power supply, please check the input power to ensure proper
grounding of the power supply system. The input power for the switch should be reliable
and secure; a voltage adaptor can be used if necessary. The building’s circuit protection
system should include in the circuit a fuse or circuit-breaker of no greater than 240 V, 10A.
It is recommended to use a UPS for more reliable power supplying. .
Caution!
Improper power supply system grounding, extreme fluctuation of the input source,
and transients (or spikes) can result in larger error rate, or even hardware damage!
2.1.1.4 Preventing Electrostatic Discharge Damage
Static electric can cause damage to internal circuits, even the entire switch. Follow
these guidelines for avoiding ESD damage:
Ensure proper earth grounding of the device;
Perform regular cleaning to reduce dust;
Maintain proper temperature and humidity;
Always wear an ESD wrist strap and antistatic uniform when in contact with circuit
boards.
2.1.1.5 Anti-interference
All sources of interference, whether from the device/system itself or the outside
environment, will affect operations in various ways, such as capacitive coupling, inductive
coupling, electromagnetic radiation, common impedance (including the grounding system)

DG-GS4200 Installation Guide
2-4
and cables/lines (power cables, signal lines, and output lines). The following should be
noted:
Precautions should be taken to prevent power source interruptions;
Provide the system with a dedicated grounding, rather than sharing the grounding
with the electronic equipment or lightning protection devices.
Keep away from high power radio transmitters, radar transmitters, and high frequency
strong circuit devices.
Provide electromagnetic shielding if necessary.
2.1.1.6 Rack Configuration
The dimension of the switch is designed to be mounted on a standard 19’’ rack.
Please ensure good ventilation for the rack.
Every device in the rack will generate heat during operation, therefore vent and fans
must be provided for an enclosed rack, and devices should not be stacked closely.
When mounting devices in an open rack, care should be taken to prevent the rack
frame from obstructing the switch ventilation openings. Be sure to check the
positioning of the switch after installation to avoid the aforementioned.
Caution！
