Figure 2-1 shows the ventilation requirements of the RG-WALL1600-S3600. Keep the device Allow at least 3.8 cm of
clearance around the ventilation openings. After connecting various cables, you should bundle the cables or place them in
the cabling rack to avoid blocking air inlets.
Temperature and Humidity Requirements
To ensure the normal operation and a prolonged use life of the RG-WALL1600-S3600, you must maintain an appropriate
temperature and humidity in the equipment room. Too high or low temperature and humidity for a long period of time may
damage the equipment.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak electricity,
and sometimes the materials may suffer from mechanical performance change and metallic parts may get rusted.
On the other hand, in an environment with low relative humidity, the insulating strip may dry and shrink, and static
electricity may occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subjected to even greater harm, as its performance may
degrade significantly and its useful life may be shortened in the case of long-term exposure that expedites the aging
process.

The ambient temperature and humidity are measured at the point that is 1.5m above the floor and 0.4m
before the equipment when there is no protective plate in front or back of the equipment rack.
Cleanness Requirements
Dust poses the top threat to the running of the equipment. The indoor dust falling on the equipment may be adhered by
the static electricity, causing bad contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the use life of the equipment, but also causing communication faults. The
following table shows the requirements for the dust content and granularity in the equipment room.

The air filter of the RG-WALL1600-S3600 must be cleaned at interval to ensure good ventilation and dust
prevention.
Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements; as such
poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The equipment room
should be protected from the intrusion of harmful gases (for example, SO
