Chapter 2 Hardware Installation
2.1 Installation Notice
To ensure the proper operation of DG-GS4526Pseries 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 within 0 to 50 °C and the humidity within 5% to 95%,
non-condensing.
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 (AC power: 100 ~ 240VAC
(50Hz))
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 DG-GS4526P series. 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:
Max Diameter (µm) 0.5 1 3 5
Max Density
(particles/m³) 1.4×1077×1052.4×1051.3×105
Table 2-1Environmental Requirements: Dust

DG-GS4526P Installation Guide
10
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.
Gas Average (mg/m³) Max (mg/m³)
SO20.2 1.5
H2S 0.006 0.03
NO20.04 0.15
NH30.05 0.15
Cl20.01 0.3
Table 2-2 Environmental Requirements: Particles
2.1.1.2 Temperature and Humidity
The switch install 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 is shown below:
Temperature: Relative humidity
Long term condition Short term condition Long term condition Short term
condition
15 ~ 30°C 0 ~ 50°C 40 ~ 65% 5 ~ 95%
Table 2-3 Environmental Requirements: Temperature and Humidity

DG-GS4526P Installation Guide
11
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 parameter of power is
shown below:
The AC input voltage: 100~240VAC
The frequency: 50~60Hz
Before powering on the power supply, please check the power input to ensure proper
grounding of the power supply system. The input source 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, 10 A.
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 discharges 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;
