2.2 Installation Preparations
Whether the W140A is properly installed has a direct impact on the QoS of the system.
Due to the huge amount of installation work, it is necessary to work out a practicable
installation scheme to effectively ensure the progress and quality of the installation
work.
Complete the following issues before installing the W140A:
1. Network planning: Defining the installation location, installation mode and
connection method of the working ground.
2. Obtaining installation approval documents: To install the W140A in any public
building or the building of any group or individual, you should ask for
permission in advance.
3. Line resource: The W140A must be connected with the upper layer network
equipment via an RJ45 Ethernet interface. You should make sure beforehand
that whether the necessary line resource is available.
4. Lightning protection measures: Determining the lightning protection measures.
If a lightning arrester is to be installed, determining the grounding method of the
lightning protection grounding wire.
5. Installation personnel: Only the trained personnel should be allowed to install
the W140A, and supervision personnel should be present.
