Installation Notice
To ensure the proper operation of QSW-8200 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 within 0 to 50 °C and the humidity within 10% 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: 90 ~ 264V (50Hz), DC
power: -40 ~ -60V)
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 QSW-8200 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:
