Five misunderstandings in the selection of electronic distribution frames (2)

Other mistakes in the selection of electronic distribution frames:

3rd mistakes, 9th pins of 9-pin jumper are easily broken

Companies that adopt the principle of 9-pin jumper have a variety of design solutions. Most of the solutions are used and 8-core Jumper the same line gauge, plug, slot, but is in the reserved position of the RJ-45 plug plus a needle, the average person does not carefully observe is very difficult to distinguish from other, see figure-1.

Figure-1

Even if the RJ-45 plug external contact Reed solution, its structure design also fully consider the reliability and safety requirements, if not intentionally with special tools to damage, its reliability is not questionable. It can be said that the probability of 9th-pin disconnection is the same as that of other 8-core disconnection. In more than 10 years of practice, no matter which company's 9-pin electronic distribution frame has heard of the disconnection problem.

4th misunderstandings. The electronic distribution frame is only applicable to units with a high level of network management.

Error! Only non-intelligent electronic distribution racks rely on high-level management departments and personnel. Because the non-intelligent electronic distribution frame requires the operator to jump the Jumper in strict accordance with the operating procedures prescribed by the operator, if wrong, the system may be wrong. In addition, the link connection relationships of non-intelligent electronic distribution frames depend on manual input, regardless of whether they are operated according to work orders. Of course, this imposes strict requirements on operators. Using such an electronic distribution frame system only increases management costs.

Intelligent Management of Electronic distribution frames is completely intelligent. It has the ability to correct errors. Even if the operator is wrong, the system will forcibly guide the operator to correct the error. Additionally, the intelligent electronic distribution frame automatically identifies the link connection relationship and updates the link database. Intelligent Electronic distribution frames can greatly reduce the dependence on operators, reduce labor intensity, save maintenance costs, and greatly improve system reliability and security.

5th misunderstandings: 9-PIN technology electronic distribution frames may cause confusion if common Jumpers are used

First of all, this possibility is very small. In the actual project, if the 9-pin jumper scheme is adopted, only the 9-pin jumper exists in the network, and no general jumper is mixed in. In addition, 9-pin jumpers generally use special colors to distinguish them from other ones. Therefore, even if other general Jumpers are mixed in, they can be easily identified. Also, in step 2, when a general patch cord is connected to the 9-pin patch cord distribution frame, the electronic distribution frame will judge that the link is disconnected because there are no 10 thousand pins to form a loop ), at this time, if it is based on the work order construction or jumper operation, LED display lights or LCD display will prompt the operator, the jumper is not completed, forcing the operator to re-operate, otherwise, the system will not allow the operator to continue working.

If it is not guided by the work order, but the operator forcibly inserts the General Jumper into the 9-pin electronic distribution frame, the system will judge that the link is in the disconnected state, but at the same time, because the 8-core line of the general jumper is in the connected state. As long as the network is connected, the IP address will be displayed on the tree structure. At this time, the network administrator will immediately find this contradiction. The network transmission is normal, but the electronic distribution frame is disconnected. There is only one reason for this, that is, the 9-pin jumper does not work. At this time, the network administrator only needs to issue a work order to disconnect the link. It is only necessary to indicate the Port location and the work order can be canceled later ), the LEDs on these two ports start to shine. Check the patch cord between this pair of shiny ports in front of the Cabinet for a clear reason. The electronic distribution frame guided by LCD is basically the same.

The use of cabling solutions for electronic distribution racks usually requires a lot of investment. It is the responsibility of decision makers to make these investments play a role. Manufacturers with high brand awareness of cabling do not necessarily have advantages in electronic distribution frames. The electronic distribution frame mainly involves electronic and network technologies, while the traditional wiring industry involves the material industry. It is not difficult to determine whether it is good or bad to carefully examine the actual use cases and customer feedback of each electronic distribution frame. The determination method provided in this article is for reference only by decision makers.
