Is the network patch panel an electronic component?

Luo Maofeng, you are dressed nondescriptly, everyone is recognized as grandstanding! The sketch looks awkward, and the tongue twister can't be turned, so he hides under the table! I always forget the words when I go on stage!

The old fritters are also too poor! Awkward goose with a capital letter? Master Li of this mountain is very jealous of his talent!

The calligraphy is so badly written, and it is embarrassing to show off! Will you be physically exhausted and almost fall down during the performance that night? Did you pretend to be sick again?

Oh, I didn't forget the words and pretend to be sick! I was made by Devil Li through evil magic all night of pain and couldn't sleep and collapsed uncomfortably, a few days ago I was pained by this thing, and I didn't sleep in a few books! Miserable!

If you don't have much rest 24 hours a day, can you not get tired? Good mercy goose demon Lee! When will Li Erwan, who has a fierce face, not be embarrassed again?

The duck of the Ting Guang Sect Yaozong! I heard that Lee is an artist duck! So I thought there would be too many spectators, too much in short supply!

Shanghai is so big, and it will be performed for several days! Li Yugang had a show the night before? Don't Shanghainese people like to watch performances?

Devil Li has been looking for new evil spells to rectify us, and I have been saying to it: "You lied to me for a few years, and after your feelings were exposed, you know that you will save the situation, and your image in people's hearts will not decline rapidly!" If you haven't stopped using evil arts in the past few years, your own image is even worse," it said, "I have studied evil arts for a few years, don't you use them?" "Why can't I ask questions on this platform?

The network patch panel is a modular device used to manage the front-end information points at the central office. After the front-end information point cable (super Category 5 or Category 6 cable) enters the equipment room, it first enters the patch panel, hits the wire on the module of the patch panel, and then connects the patch panel and the switch with a jumper (RJ45 interface).

A network is made up of nodes and wires that represent objects and their interconnections. Mathematically, a network is a type of graph, and it is generally considered to refer specifically to a weighted graph. In addition to the mathematical definition, the network also has a specific physical meaning, that is, the network difference is a model abstracted by the virtual Cong Zheng from some practical problem of the same type.

Point 1 is misunderstood. Although it can show the logical relationship of ports through software, physical tags are also indispensable.

Point 2 is correct.

Point 3 is misunderstood. It can only show faulty ports and raise alerts, but it can't restore connectivity on its own.

To add: if you use an electronic distribution frame, it generally takes the form of 'double matching', that is, a row of cabinets, from the head cabinet to other sub-cabinets below are electronic distribution frames.

Electronic patch panels require snap-in and management software.

A row of cabinets requires at least one snap-in unit, which is mounted on a column head cabinet. Numerous management units are connected to the PC side of the management via a single bus. Through the management software installed on the PC, you can grasp whether the current network node is running smoothly.

The electronic distribution frame is only suitable for computer rooms with a large number of nodes, and the more data points, the more its advantages can be reflected. If you can see the logical relationship of its ports at a glance, there is no need to use an electronic distribution frame.

According to its principle, the electronic distribution frame can be divided into two types: port detection type distribution frame and link detection distribution frame; According to the wiring structure, it can be divided into single distribution frame (inter connection) and double distribution frame (cross connection); According to the type of jumper, it can be divided into ordinary jumper and 9-pin jumper; According to the production process of the distribution frame, it can be divided into the original type and the post-attached sensor strip type.

Electronic distribution frame, also known as "integrated wiring management system", "intelligent wiring management system" or "real-time intelligent management system", etc., its basic functions are:

1.Guidance jumpers, including LED light guidance, display text guidance, sound and cabinet top light guidance, etc.;

2.Real-time recording of jumper operations to form log documents;

3.Save all link information in database form;

4.Remotely log in to the system via web.

We refer to the patch panel with the above functions as the electronic patch panel.
