The equipment installation environment cannot be surrounded with pollution
sources. If this condition cannot be met, it is recommended that the equipment be
installed in a heat exchange cabinet or an air conditioning cabinet.
Principle for Heat Dissipation of a Network Cabinet
The router equipment needs to be installed in a standard network cabinet that
complies with heat dissipation requirements of the router equipment.

Thermal Design of a Network Cabinet with Natural Heat Dissipation
When the equipment is installed in a network cabinet with natural heat
dissipation, the air duct direction of the equipment needs to be consistent with the
air duct direction of the network cabinet. The equipment can be installed
horizontally or vertically.

When the router equipment is installed in a network cabinet, the temperature
at the air intake vent cannot exceed the maximum temperature permitted by
the equipment to run normally, and the network cabinet must be capable of
dissipating the heat generated by all the equipment installed in the network
cabinet.
Fans need to have the backup function. After a fan fails, the other fans can
still work normally. A failed fan needs to be replaced in time. For more
information about the air volume of fans, see the air volume of an indoor
cabinet.
The heat dissipation capability of a network cabinet without fans is greater
than the maximum total heat dissipation consumption of the equipment in
the network cabinet, and the internal temperature of the network cabinet is
lower than the maximum working temperature of the equipment.
