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:
