Chapter 2: Hardware Installation
Installation Notice
Please follow all safety instructions to ensure proper operation of the Link5010AS-POE, your
physical security as well as the on-going warranty of the unit.
Environmental Requirements
The switch must be installed in a clean area with ample ventilation and free of
dust, 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. Please ensure 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 personal
physical injury.
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.
Dust and Particles
Dust is harmful to the safe operation of the switch. Dust can lead to electrostatic adherence,
especially under low relative humidity, causing poor contact of metal connectors or contacts.
Electrostatic adherence will result not only in 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 SO
