In the previous installments, we learned about the installation of the main parts of the chassis, but the installed process is not finished yet. Because there are still a lot of cables on the chassis panel, what are they doing? They are switches and LEDs, as well as PC speaker connections, which are connected to the motherboard. This is not a very simple matter, because these connections are more, and easy to mess up, but it is very painful to install. So today we're going to look at how to conn

Today, people need to process, store, and connect more data in a smaller area. The best way that everyone can think of is to make good use of each rack unit and make full use of its potential. This situation also applies to passive connection products. How to plan the capacity, growth, space and power supply of the data center, and how to achieve high stability and reliability in a high-density environment requires meticulous work. Requirement: ensures secure and reliable information transmissio

Misunderstandings of Integrated Wiring System Requirements 1. Use the four-port 86 panel with caution Currently, the requirements for "using four ports and 86 panels for information export and six types of information modules" are often seen in the bidding documents of engineering projects. We all know that the base box for 86 panels is small. Four six types of modules are installed in such a small space, and four coarse 6 types of cables are mounted

How do I select single-mode or multi-mode optical fiber in the Integrated Wiring project? With the development of the times, copper cables will gradually exit the market and optical fiber cables will gradually become dominant. However, the types of optical fiber are single-mode optical fiber and multi-mode optical fiber. They share the advantages of optical fiber, but also have some differences. What are their advantages and disadvantages? What kind

ATT's Integrated Wiring System, Premises Distribution System, integrates the entire communication, including wiring required for voice, data, images, monitoring, and other devices with a single wiring System.International StandardsThe components used by ATT's structured cabling system are all designed by Bell Labs according to the standards of the American Electr

Problems related to shielding systems in Integrated Wiring In the Integrated Wiring System, unshielded and unshielded systems are widely used. The shielding system comprehensively utilizes the balanced principle of twisted pair wires and the shielding effect of the shielding layer. It has good electromagnetic compatibility and can prevent electromagnetic interference and electromagnetic radiation. The adv

Now the elevator is installed in the monitoring camera system, but because the elevator environment complex causes many video surveillance images in the elevator well road environment by different degrees of interference, monitoring effect is not very good. In response to this problem, and the associated electronics professionals pointed out that if the installation of elevators in some wiring skills, it can be to a large extent to alleviate such inte

20-smart Wiring It is not easy for programmers xdjm to buy a house. It has been laid by a developer or a second-hand house, and cannot be swallowed up by an installer, a building material dealer, a furniture dealer, or a soft contractor. We need to arm ourselves with knowledge and fight together with js to the end. Let's take a look at the fence home decoration series compiled by Leng Shan.

With the development of computer and network technologies, servers, network communication equipment and other IT equipment are moving towards miniaturization, networking, and rack-based Development. The demands for Cabinet Management in data centers will grow. A cabinet or rack is no longer a container used to hold servers or other devices, but is no longer a low-value or ancillary product in IT applications. In the field of Integrated Wiring, cabinet

Optical Fiber Connection Technology in Integrated Wiring Fiber Optic Cable has become an indispensable part of network cabling design. It has many advantages such as high communication capacity, strong anti-interference performance, and strong security. It is widely used in cabling networks and faces market demands, the Optical Fiber System has also entered the level and desktop applications. In current generic optical fiber cabling networks, the

With the development of the network, as a kind of medium for transmitting data in the integrated wiring system, optical fiber is more and more used by people because it has the advantages of high transmission rate and far distance. As we all know, optical fibers are non-conductive, can be free of shock current, optical fiber cable also has good protection performance, the metal components in the cable to the ground insulation value is high, the lightn

The pitch of the copper layer in DXP is modified without affecting the wiring of each layer. In the clearance of rule, create a new rules Clearance1 (name can be customized), Then, in the Where, select Advanced (Query) in the "matches" box, Click Query Builder, and then the Building Query from board dialog box appears, In the first row of this dialog box, select Show all levels (default for this item). Then select Object Kind is in the Drop-down menu

A few days ago, a trading company in Huaqiang Electronics Mall bought an Alpha G3 router for commercial Internet access. Customers can suggest that in the use of the LAN in the average computer every hour will drop five or six times of the line. So that they can not normal access to the Internet, after receiving the phone, the author and Alpha technicians rushed to the scene. First, the company's network is understood, they are in the telecom application of 2M Broadband ADSL packet annual fee. T
