On the role of identification in intelligent wiring

For network cabling in the identification problem, many network products providers have put forward their own solutions, the various families are trying to solve the current network cabling and management of a major problem. But after a little analysis, we find that in fact, behind this phenomenon have more or less common ground, that is, the network in the initial construction process of the standard degree, the detailed degree of planning, the future of the network retention degree, the standard of construction and marking the implementation of the standardization of considerations and standards, these are deficient.





in fact for a development of the company, the beginning may be in accordance with the 200-point design of the network architecture, cabinets, servers, routes, HUB, and so clear in the chest, decorate quickly and clearly, even for some changes, the head of the network management will be clearly remembered. Since it is simple and lively, the majority of network management and construction personnel will not be identified for each point, for the flow of functions such as record, because for the initial construction of the network, or even a period of time is not much use; but the network changes after a period of time, the trouble will ensue, Let's look at two simple pictures, at a glance.





Although at the beginning, we also have a sense of the line, emissions to do good-looking generous, easy to find, but with the increase in the user side, jumper increase, the whole situation has changed. Imagine, in the case of Fig. 2, if there is a problem at one end, how to find, how to locate, if there is no record, the original 20 minutes can be done, network management personnel to at least half a day.





before we talked so much about the situation, is to tell you that the standardization of network wiring is more and more attention to solve the problem in fact there are many ways, here, just want to talk about the most traditional and most effective, experienced the longest market test and baptism of the solution-logo system in the wiring of the application.





we all know that the intelligent wiring in Europe and the United States than more than 20 years ago, so their wiring system relative norms, because they have been followed by an industry standard Tia/eia 606 Standard, I do not want to talk about this standard content, just want to say that only have the industry standards, It is worth celebrating that China has also launched the white Paper on the design and construction of data center cabling system this year, all of which illustrate that China's network wiring is also maturing.





Let's take a specific look at the application of the logo system in wiring, in fact, in a period of time, there are network management personnel to try the application of the figure 3, both the use of self-adhesive paper and handwriting on the network line for calibration, but a long time to find it easy to fall off, handwritten content will vary, there is no fixed way of expression, difficult to understand.





so in the Tia/eia 606 specification and "Data center wiring system design and construction technology white paper" out, logo application unified demand more and more clear, the process of network construction is also more clear. The whole network construction divides into four stages, namely design, construction, acceptance test, daily maintenance and management, greatly enhance the management efficiency of the wiring system, provide the omni-directional support to the user's later maintenance, have this kind of specification, before the problem solves. The materials used in the label, the printed content, the way, the presentation of the format and even with the appropriate environment, testing conditions, and so on, and in the solution of these problems, do mature is the United States company, the following we will be specific to see how the United States Brady is in accordance with the Tia/eia 606 specifications and the " Data center Cabling System design and Construction technology white paper "to provide solutions."





according to the standard, the label material mainly divided into two kinds, one kind is the line application, its main is the vinyl or the cloth, the Brady material model is b427/b580/b499; another kind is the plane label mainly pastes on the panel, the asset and so on the plane Brady's material model is the b423/b580, And for outdoor environments require the use of B580 all-weather materials.





according to the standard, for printing the main requirements to meet the UL969 standard, and is the thermal transfer of the printing method; At the same time, Brady's printing solutions are mainly two types, one is a large number of printing, suitable for more than 3,000 works, the printer model is IP300; Another kind of handheld printer is mainly suitable for 1000 points and the following network architecture, the printer model is TLS2200 and BMP21, as shown in Figure 4.





according to the standard, for the entire network we mainly consider the following kinds of calibration: data center of each cable, cable, wiring equipment, end contact, grounding devices, laying pipelines.





let us look at the specific form of the label is how the specification, the specific definition format:





(1) cabinet/rack Identification





For example: The Cabinet of the AJ05 floor network on the third floor of the data center is labeled: 3aj05 (as shown in Figure 5)




The format of the
identifier is: nnxxyy,nn= floor number, xx= floor grid column number, yy= floor grid line number





(2) cable and jumper identification




The cable on the
connection needs to be labeled at both ends with a label to mark its distal and proximal addresses. Management identification of cables and jumpers: p1n/p2n;p1n= near-end racks or cabinets, wiring racks, and specified ports; p2n= remote racks or cabinets, distribution rack order, and specified ports.





For example, the cables shown in Figure 6 that connect to the first position of the wiring rack can contain the following tags: aj05-a01/aq03-b01. And the same cable in the cabinet AQ03 will contain the following tags: aq03-b01/aj05-a01.





(3) Wiring frame identification




Identification of the
wiring frame, the numbering method of the wiring frame shall include the number of the rack and cabinet and the position of the wiring frame in the rack and cabinet.




Identification of the
wiring rack port, for example, the fourth port of the second wiring frame 2 in the cabinet 3aj05 can be named 3aj05-b04.





format: nnxxyy-a-mmm,nn= floor number, xx= floor grid column number, yy= floor grid line number, a= wiring frame number (A-Z, from top to bottom), mmm= line pair/core fiber/port number.




Identification of
wiring frame connectivity, wiring frame Connectivity Management identification: P1 to P2, where p1= near-end racks or cabinets, wiring racks and port numbers; p2= remote rack or cabinet, wiring rack order, and port numbers (as shown in Figure 7)





(4) Asset and equipment identification





Assets and equipment identification, through the way of labelling to specify the location of equipment or assets and the person responsible.





Finally, for networks larger than 5,000, Brady recommends using the necessary electronic network document management software, such as the NetDoc provided by Brady, to help customers better control their networks so that they can move, add, change faster, and easily, reduce downtime, increase information storage, Dramatically shorten the time required to find and troubleshoot problems.





Identifies the application and specification formats in the network, and related equipment and requirements, many people may not be able to do, the author also gave three examples: for 500 points below, 1000 points, 5,000 points over the selection of network identification and related equipment configuration, I hope this article can help readers understand the role of the logo.
