2.2 Installation Environment Requirements
To ensure the normal operation and prolonged service life of the device, the installation site must meet the following requirements.
You are not advised to install the RG-S2915-L series switches in a ELV box.
2.2.1 Ventilation and Cooling Requirements
Maintain a minimum clearance of 10 cm (3.94 in.) on both sides of the chassis and around the back panel of the switch for normal air
ventilation and heat dissipation. After various cables are connected, bundle the cables or place them in the cable management bracket
to avoid blocking air inlets. Dust the device every three months to avoid blocking the ventilation openings on the housing.
2.2.2 Temperature and Humidity Requirements
To ensure the normal operation and prolonged service life of the switch, maintain an appropriate temperature and humidity in the
equipment room. The equipment room with too high or too low temperature and humidity for a long period may damage the switch.
 In an environment with high relative humidity, the insulating material may have poor insulation or even leak electricity.
Sometimes it is also prone to changes in the mechanical properties and causes rusting of metal parts.
 In an environment with low relative humidity, the insulating strip may dry and shrink. Besides, static electricity is prone to occur
and damage the internal circuits of the switch.
 A high ambient temperature is more harmful to the device. It not only deteriorates device performance but also causes various
hardware faults.
The table below lists the temperature and humidity requirements of RG-S2915-L series switches.

Relative Humidity
0 ºC to 50ºC (32°F to 122°F)
10% to 90%
Requirements for ambient temperature and humidity of sampling points:
The ambient temperature and humidity of the switch are measured at the point that is 1.5 m (59.06 in.) above the floor and 0.4
m (15.75 in.) before the switch rack when there is no protective plate in front or at the back of the rack.
2.2.3 Cleanliness Requirements
Dust poses a major threat to the switch. 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 requirements for the dust content
and granularity in the equipment room are shown in the following table.

Apart from dust, the salt, acid, and sulfide in the air in the equipment room must meet strict requirements. These harmful substances
will accelerate metal corrosion and component aging. Therefore, the equipment room should be properly protected against the
intrusion of harmful gases, such as sulfur dioxide, hydrogen sulfide, nitrogen dioxide, and chlorine gas. The following table lists limit
values for harmful gases.
