4.1.1.2.2 Requirements for Running Environment B and Installation Planning
This section describes the requirements for equipment location selection,
dustproof and waterproof, surge protection and grounding, heat dissipation,
cooperation between air ducts, power supply of equipment, cabling space,
selection of network cabinets and outdoor cabinets, and corrosion protection
when equipment is installed in running environment B.
Requirements for Selecting a Site for Equipment
To ensure that equipment operates stably over a long term, the site of equipment
in environment of class B must satisfy requirements with respect to
communication network design, communication technologies, hydrographic,
geology, and transportation.
When selecting a site for equipment, make sure that the site satisfies the
following requirements:

NOTE
Shock response spectrum is a curve of the maximum acceleration responses generated
by the equipment under specified impact excitation.
Static payload refers to the capability of the equipment in package to bear the
pressure from the top in normal pile-up method.
Equipment is kept as far as possible from the presence of harmful gases, dust,
noise, and excessive vibration. To achieve this level of protection, ensure that
the equipment is installed in a fully sealed enclosure or cabinet.
Equipment is kept away from strong electromagnetic interference sources to
ensure that its electric field strength is less than 3 V/m, and the power
frequency magnetic field is below 3 A/m. For sites that cannot avoid strong
interference, it is recommended that you use the shielded chassis or cabinet
to ensure that the equipment works properly. If used in an electrical power
substation or a similar environment, ensure that the electromagnetic
environment of the equipment meets power industry standards.
Equipment is kept away from a tree or other plants. Otherwise, insects may
be absorbed by fans, resulting in damage to fans.
Equipment is installed at least 500 m( away from the seashore. If the network
cabinet or outdoor cabinet is configured with fans, ensure that the air intake
vents do not face the direction in which the sea wind blows.
In an area prone to snow or rain, the vents of the network cabinet or outdoor
cabinet are at least one meter higher than the position with accumulated
water or snow.
Equipment is installed in a position away from water drips (outdoor part of
an air conditioner and dripping eave).
