easily.

The front and rear of the chassis must remain unobstructed to ensure adequate airflow and
prevent overheating inside the chassis.
2.2.4

Temperature

To ensure normal operation and prolonged service life of the equipment, maintain an
appropriate temperature in the equipment room. Otherwise, the equipment may be damaged.

A high temperature can accelerate the aging process of insulation materials, greatly
reducing the availability of the equipment and severely affecting its service life.
See Table 1-8 Technical Specifications
Note
The operating temperature is measured at the point that is 1.5 m (4.92 ft.) above the floor and
0.4 m (1.31 ft.) before the equipment with no protective plates in front or at the back of the
equipment.
2.2.5

Humidity

To ensure normal operation and prolonged service life of the equipment, maintain an
appropriate humidity in the equipment room. Otherwise, the equipment may be damaged.
 In an environment with a high relative humidity, the insulating material is prone to poor
insulation or even electricity leakage.

In an environment with a low relative humidity, the insulating strip may dry and shrink,
resulting in screw loosening. Furthermore, internal circuits are prone to static electricity.
See Table 1-8 Technical Specifications
Note
The operating humidity is measured at the point that is 1.5 m (4.92 ft.) above the floor and 0.4
m (1.31 ft.) before the equipment with no protective plates in front or at the back of the
equipment.
2.2.6

Cleanliness

The indoor dust takes on a positive or negative static electric charge when falling on the
switch, causing poor contact of the metallic joint. Such electrostatic adhesion may occur more
easily when the relative humidity is low, not only affecting the service life of the switch, but also
causing communication faults. The following table lists the requirements for the dust and
particles in the equipment room:
for the temperature requirement.
for the humidity requirement.
