8. Bind the cable with a cable tie and cut the redundancies of the tie.
9. Run the ping command to check the connection between both ends of the
new network cable. If both ends fail to communicate normally, check whether
the network cable is damaged or whether the connectors are secured.
Follow-up Procedure
After replacing a network cable, collect the tools and the replaced cable. Do not
place the old and the new cables together to avoid confusions.

4.2.12.1.1 Environmental Requirements for Equipment Room
Requirements for Selecting a Site for Equipment Room
When designing a project, consider the communication network planning and
technical requirements of the equipment. Also consider hydrographic, geological,
seismic, power supply, and transportation factors.
Construction, structure, heating and ventilation, power supply, lighting and
re-
proof construction of the equipment room should be designed by specialized
construction designers to suit the environmental requirements of devices. The
equipment room should also follow local regulations concerning the industrial
construction, environmental protection,
re safety, and civil air defense.
Construction must conform to government standards, regulations, and other
requirements.
The equipment room should be located in a place free from high temperature,
dust, toxic gases, explosive materials, or unstable voltage. Keep the equipment
room away from
signicant vibrations or loud noises, as well as power transformer
stations.
The specic requirements for selecting a site for an equipment room are as
follows:
● The room should be located at a distance of at least 5 km (3.11 mi.) from
heavy pollution sources such as smelting and coal mines. It should be located
at a distance of at least 3.7 km (2.30 mi.) from moderate pollution sources
such as chemical, rubber, and galvanization factories. It should be located at a
distance of at least 2 km (1.24 mi.) from light pollution sources such as
packinghouses and tanyards. If these pollution sources cannot be avoided,
ensure that the equipment room is upwind of the pollution sources. In
addition, use a high-quality equipment room or protection products.
● The room should be located away from livestock farms, or be upwind of the
livestock farms. Do not use an old livestock room or fertilizer warehouse as
the equipment room.
