Structured Cabling System is divided into four simple steps:
The first choice of equipment.
1. Problem
Cable connected to the workstation if there is no cable or summary of the devices is the choice of improper equipment, will cause the entire structure of the integrated wiring system is unable to carry out construction and the cost increase.
2. Solution
Before entering the construction site, according to Structured Cabling System standard design detailed blueprint for a comprehensive cabling system, including cabling system with the structure of five sub-systems. Side with the construction and supervision of audit agencies, modify, three confirmed and then Construction.
3. Procedures
1. By Structured Cabling System standards, the construction of the building floor plan, decoration floor plan and site investigation, a comprehensive blueprint for the cabling system.
2. Integrated Cabling System blueprint for the completion of the design and construction of the Times and the regulator to examine, modify, three confirmed
3. Amended if some of the construction side, and supervision institutions, the construction side, in accordance with the actual situation without violating the Structured Cabling System under the premise of the standard changes.
4. Revised blueprint for a comprehensive cabling system design, construction and supervision of audit agencies, modify, tripartite confirmation, the blueprint for the eventual construction.
The second step of the integrated wiring system from the measurement
1. Problem
In the high-speed local network, cable links must be tested before use. EIA / TIA 568586A commercial building on the drafting of the cabling standards for the level of the largest cable link transmission distance of 100 meters. In order to prove that meet the standards and reduce waste and loss, thus it must do so before the release of field measurements. Because the system is mainly the level of cable, in most cases this requirement is appropriate; However, there are some special circumstances, such as panels, the TAC guitar line or terminal position may change transmission rate. This occurs, not measured by the length of cable length can lead to insufficient data final tests fail.
2. Solution
The level of use of digital cable products, which simplifies the button again detection cable length of the work. For the length of cable, cable measuring the level and the estimated length of stay of all the panels, the TAC statement by the length of the cross-wiring together for the release length. Have a simple calculation: (longest cable + shortest cable) / 2 * 120% of the value of the length of actinomycetes.
Procedures
Construction recorded in the minutes of cable length
1. Field measurements, the distribution of labeling and record level of cable length.
2. Cables level measurement in the field of work of the TAC and the final statement after the completion of standard cable will be long and estimated to remain panel line, the TAC statement by the inter-connection of the total combined length of cable by the entire chain length.
3. Exercises will be conducted to test and record the length of the comparison. Length difference between the two within about 10 feet.
The third step to do cable logo
1. Problems
The level of cable without labels or labels in the installation process or not after the end of the installation, which will increase consumption and artificial do not facilitate the maintenance of the building after completion and production information. For example, if there is a logo or logo without logic means to pay more manpower and resources to do testing and find, in effect increasing the construction cost more.
2. Solution
Using a pre-release of the widely used identification system simplified, horizontal cables named. Buildings will be divided into several parts, and to every part of a logo, construction workers will be marking each cable, audio generator and the line-line network will not be required. And, if used in the construction of the logo is a logic system, when the end-users of facilities, construction drawings have been corrected or improved up very easily.
3. Procedures
1. Construction site will be divided into parts, according to each floor, regional, the only room for the logo. Such as 1234, these easy-to-understand ABCD logo
2. Terminal and all equipment, the equipment box marked and named, such as equipment, pay-guitar lines and wiring blueprint for the panel to reflect the corresponding logos.
3. Wiring at the spot can be done with identification labels. Durable paper or label Damaji, number of labels do that.
4. Accordance with the blueprint for the end of cabling.
5. Guitar lines, in the node within six inches and re-panel logo.
6. Blueprint to improve and make changes in the cabling structure and modified logo.
4. Cable logo recognition method
1. Use of the line-line network confirmed
2. Confirmed by open computer
3. Line "hot swap" confirmation
4. Copy of the data confirmed that the method is relatively complex, I will not elaborate on, we hope that the self-study.
Step 4 release before the finishing line
1. Problem
When the cable pull into vertical alignment or along the walls at the same time pull as many cables will save time and effort. However, many in the cable heap of PVC pipe or trough in the tie, turning the Banzhu or staggered together (in particular attention should be paid to six cables, so as to avoid the link tests fail). Solution of the trip will end or damaged cable cutter sequence, or even a broken cable, in particular the five small cable.
2. Solution
In order to prevent cable when this happens, carefully prepared cables to the head is very important. Sloshing cables, knocking them into a streamlined structure, the head lubrication after carefully Plug the cable shafts or PVC pipes embedded in the pipeline so you can prevent Banzhu and cable staggered.
3. Procedures
1. Planned to pull together the number and type of line.
2. Arrangements for the line and Xianhe, such cables can be put into good ducts in the plan.
3. Elections 23 cable - because they have to work in the same environment - they will be placed about 30 CM from the first place. With a cloth and the first group will be the first line to wrap up spiral-shaped, in order to protect the cables below.
4. Until completion of the above methods as all cables.
5. Using slipknot cable will link with the head, or even in the threads of the.
6. A cabling installers to hand side of the work area cable. Gently put the cable into another person PVC pipe to ensure that no tie, staggered, misunderstandings, to avoid damage to cables. Installation of two officers should be able to contact or by voice or by walkie-talkie contact.
7. If the cable was pulled out at the other end, then removed cable counterparts.
8. Until completion of the above methods as all cables.
In accordance with the above method Structured Cabling will save a lot of time and lower the cost of the project, and construction supervision, and to reduce unnecessary bickering and differences. |
