Ruijie RG-EG210G-E Series Routers Hardware Installation and Reference Guide
Preparation before Installation
recommended to clean the router at regular intervals (like once every 3 months). Especially, avoid dust from blocking the
screen mesh on the back of the cabinet.
2.2.3 Temperature and Humidity
To ensure the normal operation and prolong the service life of router, you should keep proper temperature and humidity
in the equipment room.
If the equipment room has temperature and humidity that do not meet the requirements for a long time, the equipment
may be damaged.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity. Sometimes the materials may suffer from mechanical performance change and metallic parts may get
rusted.
In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity may
occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subject to even greater harm, as its performance may
degrade significantly and various hardware faults may occur.

Relative Humidity
0 ºC to 40ºC (32ºF to 104ºF)
10% to 90% (-40ºF to 158ºF)
The requirements for the sampling site of the temperature and humidity in the operating environment of the device
are as follows:
There is no protective plate at the front or back of the equipment rack.
The vertical height is 1.5 m above the floor.
The distance from the front panel of the equipment is 0.4 m.
2.2.4 Cleanness
Dust poses a severe 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 useful life of the equipment, but also causing communication faults.

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 such as sulfur dioxide, sulfured hydrogen, nitrogen dioxide, and
chlorine.
