What are the steps of network generic cabling
As for the system integration of the generic cabling project, it is mainly divided into three main stages: design, construction, test and acceptance. The design stage is before the "scheme demonstration", the construction stage is in the middle, and the test and acceptance stage is after the "index test". Now let's follow Wuxi Dehang Technology Co., Ltd. to understand the specific steps!
1. Survey site
The main task is to negotiate with customers about the network requirements, survey the buildings on site, survey the wiring construction site according to the requirements for the location and number of information points put forward by users, refer to the building plan, decoration plan and other materials, combine the network design scheme, preliminarily reserve the number and location of information points, and carry out the preliminary positioning of trunk routes and cabinets.
The survey objects include: building structure, location of machine room (equipment room) and wiring management room, routing, electromagnetic environment, appearance of wiring facilities and damage to buildings. It is also necessary to consider avoiding strong current and other lines while using the existing space, and make a survey report on integrated wiring. 2. Planning and design
The rule design of the project will have a decisive impact on the whole wiring process. Therefore, the cost budget, application needs, construction progress, etc. should be comprehensively considered according to the research results, and a detailed design scheme should be started. Under the guidance of the professional standards and regulations of the generic cabling system, fully consider the requirements of the network design scheme for the cabling system, conduct a feasibility analysis of the overall cabling system, such as spatial distance, bandwidth, information point density and other indicators, and carry out detailed design of each subsystem.
If the building cluster is under preparation, the generic cabling scheme should be put forward in time, and specific requirements should be put forward for the architectural design according to the overall layout and routing conditions, such as the connection of trunk channels between buildings, routing specifications of channels between floors, pipeline embedding, etc., so that the subsequent construction can proceed smoothly. If the wiring system design scheme has major defects, it will cause irreparable losses once the construction is completed. Therefore, users, network scheme designers and cabling engineers should participate in the review of the scheme. If possible problems are found, the scheme must be reviewed after modification until the scheme is formed.
3. Construction scheme
Determine the detailed construction details (such as wiring routing, punching holes in the wall, etc.) according to the wiring system design scheme, comprehensively consider the management and operation in the design implementation, designate the project leader and project supervision personnel, and plan the contents of the construction organization and management of each material, each work, and internal and external coordination. The cooperation degree of the user shall be considered in the construction scheme. It is better for the user to know the damage degree of the wiring scheme to the pavement and buildings and obtain the approval of the management department of the other party. The construction scheme shall be negotiated with the user, approved and signed by the user, and coordinated by the designated person in charge.
4. Budget estimate
The budget estimate is mainly based on the building plan and other data to settle the consumption of wire materials, calculate the cost of wiring materials, wiring tools, labor costs and construction period.
5. Site construction
The implementation phase of the generic cabling system mainly includes civil construction: coordinate the construction team to negotiate with the owner on responsibilities, and propose cabling license, mainly including drilling, wiring, information socket positioning, cabinet positioning, and making wiring marking system. Technical installation: mainly installation inside the cabinet, information module and distribution frame. The interior of the cabinet shall be arranged neatly and reasonably, with distinct blocks and clear marks for future maintenance. Different brands of products may have different special equipment for wiring.
The commander on the construction site shall have high quality, fully understand the wiring design scheme, master the corresponding technical specifications, and make correct on-site judgment when necessary. When the decoration and wiring are carried out at the same time, the wiring should strive to take the initiative, conduct early mobilization survey, and do what can be done in advance, such as trenching, drilling, pipe laying, and planned construction. For problems that cannot be solved at the moment, the designer must modify the design scheme as soon as possible and come up with solutions as soon as possible.
6. Test acceptance
Carry out field certification tests for various technical indicators of the wiring system according to the corresponding wiring system standards and specifications. Information point test: 12 point tester is generally used, which can be performed by a single person with high efficiency. It is mainly used to test the on-off condition. The deep test can usually use the FLUKEDSP called 00O or DTX cable tester. According to the TSB-67 standard, it can test the wiring diagram (WireM print), length (Len clumsy), attenuation (AMenu pa on), near end crosstalk (NEXT), propagation delay and other data, The test report can be printed online. Load test: loading network equipment After that, part of the network connectivity is sampled. Completion acceptance review and handover of technical documents.
7. Document management
After the project acceptance, an acceptance report must be provided to the customer, including the actual material consumption table, test report, cabinet wiring diagram, floor wiring diagram, information point distribution diagram, optical fiber, voice and video backbone routing diagram, etc., to provide data basis for future maintenance.
8. Wiring maintenance
When the communication line and connection hardware of the integrated wiring system fail, it should respond quickly, provide on-site maintenance, eliminate the fault point, and expand and modify the existing wiring system according to customer needs.
