Chapter 2 Hardware Installation
2.1 Installation Notice
To ensure the proper operation of SS2R24/48G4i 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 right range of power input AC power 100 ~ 240VAC (50 ~ 60Hz).
„ The switch must be well grounded in order to avoid ESD damage and physical injury of people.
„ The switch should avoid 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 SS2R24/48G4i 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
