General wiring points to note

For the network before the work, the focus is to ensure the quality of wiring. This is the prerequisite for the healthy operation of the network, and many units of network management personnel may not participate in the wiring phase of the work, because most units will be the network wiring to the infrastructure projects, which can easily cause problems in the work interface. For wiring, cabling products manufacturers provide 15-year warranty, the premise of the quality of the main two, first, the project needs to be certified by the manufacturer of engineers involved in design, construction. Second, must be in accordance with international standards for each link certification test, each link must have a test report. So for the network management personnel is the most important test report, regardless of whether the network management personnel involved in wiring construction, as long as the qualified test report can be considered wiring qualified, you can carry out the next step of the network opening work. But there are many customers in the wiring process should pay attention to the matter is not very understanding, so we summed up in the wiring of some of the problems and combined with some user experience for your reference:
Standard and production of line marking
The connection of the information outlet because of the color mark, just follow the color with the card clamp to push the line to the top
Making of RJ-45 plug
What are the main steps of wiring construction?
For:
Survey site, including the route by, the need to consider concealment, damage to the building (structural characteristics), in the use of existing space at the same time to avoid power lines and other lines, the scene in the case of cable and other necessary and effective protection needs,
Construction workload and feasibility (such as hit the Wall eye, etc.) planning and design and budget, according to the above situation to determine the route and apply for approval, if necessary in the load-bearing beam on the wall when the need to apply to the management department, or violate the construction regulations. The whole plan and the degree of destruction should be approved by party A and management. Revise the plan. On the basis of the formal planning of the final licensing procedures, the calculation of materials and employment, the cost of the design implementation of the management operation and so on to propose budget and duration and construction plans and arrangements. The degree of coordination of the user side needs to be considered in the implementation plan. The implementation of the program needs to negotiate with the user to endorse the signature, and designated coordination responsible personnel designated project leader and engineering supervision personnel, responsible for planning preparation, maintenance, user side coordination requirements and other aspects, put forward the timetable for the co-ordination of departments, responsible for internal and external coordination and construction organization and management.---http://bianceng.cn

Site Construction
Field certification test, Production test report
Make wiring marking system: wiring The marking system to follow the TIA-606 standard, marking to have more than ten years of warranty acceptance, documentation. In the above links must establish a sound document, as part of the acceptance.

Common mistakes in line playing
The common error of the line is open, short circuit, reverse connection (two of a pair of lines crossed, such as 1 corresponding 2,2 corresponding 1). Another error is bridging, such as 1, 2 corresponds to 3, 6. The main causes of this error are two. One end of the cable uses the T568A standard, while the other end of the cable uses the T568B standard. Second, in the practical application of the network, it is sometimes necessary to use this crossover wiring. Cross-wiring is required when a hub is cascaded with a hub. In addition, when the PC and PC docking (not through the hub), you also need to use cross wiring. Some users use the cross wiring can also be connected to the Internet, and use the correct wiring can also carry out the hub of the cascade. This is because the hub they use is the smart hub. The hub can automatically swap the wiring around. But that does not mean that the way the line is made is correct. Finally there is a mistake is a string around. This result is usually caused by a pair of 1, 2, 3, 4 for a pair, 5, 6 for a pair, 7, 8 for a pair. The network uses 1, 2, and 3, 6 instead of 3 or 4 for communication. This faulty wiring cannot be checked with an eye or a multimeter because its end-to-end connectivity is normal. And the biggest harm of this error wiring is that it will produce very large near-end crosstalk. It does not cause the network to be disconnected, but makes the network run slowly, Shitong. It is a soft fault and it is troublesome to check it when the network is running.
Problems to be paid attention to in wiring construction
When a cable has an extra cable at two terminals, it should be cut off as long as it is needed, rather than being rolled up and bundled.
The distance between the cable's joint and the winding line should not exceed 2 centimeters. Too long will cause a large near-end crosstalk.
At the junction, the outer protective layer of the cable needs to be pressed in the connector and not outside the connector. Because when the cable is subjected to the external pull force is the entire cable, otherwise the force is the cable and the connection of the metal part of the connector.
In the cable wiring construction, the cable tension is bound. Generally 9 kg or so. Please confirm its pull with the cable supplier. Too much tension will damage the symmetry of the cable.
Cabling System Testing Process
Cabling System testing is generally divided into three steps.
Wiring construction personnel with the test, at this time only testing the cable, cable line method, length and the direction of the cable. This test can be done using the F620 of the fluke company. Usually this is a general cable detection tool for the wiring builders.
When the cable wiring construction completed, the need for all cable systems certification test, at this time according to some international standards, such as tsb67,iso11801, the cable system to carry out a comprehensive test to ensure that the installed cable system to meet the standards. At this time need to test a variety of electrical parameters, and finally to the test report according to each link. The test report includes the time of the test, the location, the operator's name, the standard used, and the results of the test. Of course the report of the test should preferably have Chinese results. The dsp100/2000/4000 of fluke can be tested for different levels of cable certification.
Finally, the completion of construction, the need for a third party to the cable system sampling. Sampling is representative of justice and acceptance of construction. The ratio of cable system sampling is usually 10% to 20%.
