Confirm that the rack and workbench are solid enough, and can bear the weight of switch
and its installation accessories.
Confirm that the rack and workbench are grounded properly.
To ensure long-term stable work of switch, the installation place should also meet the
following several requirements:
Requirements for temperature and humidity
To ensure normal operation and service life of switches, it’s necessary to keep certain
temperature and humidity in the machine room. Where the humidity in the machine room is
too high for a long term, it’s easy to cause poor insulation performance of insulating materials
and even electric leakage, and it’s also easy to cause change in mechanical performance of
materials, corrosion of metal components and other phenomenon sometimes; where the
relative humidity is too low, the fastening screw may be loosened by the air shrinkage of
insulating spacer, and meanwhile it’s easy to generate static electricity in dry climate
environment and damage the circuit of switch; too high temperature is more hazardous,
long-term high temperature will accelerate the aging of insulating materials, reduce greatly
the reliability of switch, and affect significantly its service life.

Cleanliness requirement
Dust is a main hazard for the operation safety of switch. The dust accumulated on the machine
indoor may cause electrostatic adsorption, which may cause poor contact of metal connectors
or metal contact points. In particular, when the relative humidity indoor is too low, it’s easier
to cause electrostatic adsorption, which may not only affect the service life of device, but also
improve the risk of communication fault.

In addition to dust, the machine rooms of switches also have strict requirements for the
content of salt, acid and sulfide in the air. Such harmful gases will accelerate the corrosion of
