2.1 Installation Notice
To ensure the proper operation of switch 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 range of AC power input: 100 ~ 240VAC (50/60Hz) and DC
power input：-52~-57V;18A.
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 2-2 Environmental Requirements: Particles
2.1.1.2 Temperature and Humidity
Although the switch is designed to use fans, the site should still 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:

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.
