Functions and uses of network cabinets, jumper frames and patch panels
When it comes to network cabling, when it comes to network cabinets, everyone is familiar. Today, let’s learn together what is a patch panel, what is a patch panel, what is a cable manager, and what are they used for.
- What is a jumper frame
The so-called jumper frame is composed of flame-retardant modular plastic parts, which are equipped with a number of toothed bars for terminating the wire pairs. With the 788J1 special tool, the wire pairs can be “punched” to the jumper frame in sequence in order to complete the operation. For the termination of voice backbone cables and voice horizontal cables, the commonly used specifications are: 100 pairs, 200 pairs, 400 pairs, etc.
Why use a phone jumper?
Generally used in computer rooms with program-controlled telephones. After the telephone line is connected to the program-controlled machine, the line of the extension number is connected from the program-controlled machine. Then put all these wires on the jumper frame, and then go out from the outlet frame to your extension number, and you mark the number on the patch frame. So there’s something wrong with that phone. When you overhaul, look at the label on the patch panel, and then it’s easy to find the line along the line. If you don’t need a jumper frame, you will be tossed to death. The lines are all jumbled up.
The role of jumper
- It can reduce the loss of network equipment interfaces such as switches.
For example: network management personnel will often plug and unplug lines and test lines, which will cause the switch to become loose and not tightly connected for a long time. , install it on the jumper frame, and then make a small section of network cable – commonly known as a jumper, and connect the jumper frame with the switch, so that the network manager only needs to unplug the RJ-45 at one end of the jumper frame when testing. The interface is as follows. Jumper racks are much cheaper than interface cards on switches.
- The wiring is neat, tidy, beautiful and professional
In appearance, the wire jumper looks like rows of fish bones, also known as fish skeletons. Usually used for telephone connections. The function of the jumper frame is to provide a convenient and fast termination method for high-density voice data cable connection. Jumper racks can be used for both wall mounts and vertical cabinets. The jumper has a wide range of functions and is suitable for high-speed applications in all voice communication systems and multimedia.
The jumper frame generally cooperates with the 110 connection block to play the role of the jumper frame. There are many types of jumper frames. Currently, there are 50 pairs and 100 pairs with legs and no legs on the market. There are 4 pairs and 5 pairs of connection blocks to choose from. The function of the jumper frame is also related to the type of jumper frame. Different types of jumper frames have different functions. The user should choose the appropriate jumper frame during the integrated wiring.
cable manager
- What is a patch panel
Equipment used for end-user lines or trunks and capable of provisioning and connecting them. The patch panel is the most important component in the management subsystem, and it is the hub to realize the cross-connection of the two subsystems of the vertical trunk line and the horizontal wiring. Patch panels are usually mounted on a cabinet or wall. By installing accessories, the patch panel can meet the needs of UTP, STP, coaxial cable, optical fiber, audio and video. Distribution frames commonly used in network engineering include twisted pair distribution frames and optical fiber distribution frames. According to different places of use and uses, it is divided into two categories: main distribution frame and intermediate distribution frame.
The purpose of the patch panel
The positioning of the distribution frame is a modular device that manages the front-end information points at the central office. The front-end information point cable (Category 5e or Category 6 cable) enters the equipment room firstly into the patch panel, attach the cable to the module of the patch panel, and then connect the patch panel and the switch with a jumper (RJ45 interface). .
Generally speaking, the patch panel is used to manage the equipment. For example, if there is no patch panel, the front-end information point is directly connected to the switch. If there is a problem with the cable, it will be re-wired. In addition, the management is also confusing, and multiple plugging and unplugging may cause damage to the switch port. The existence of the patch panel solves this problem, and better management can be achieved by replacing the jumper.
If a building has only four floors, the main equipment room is set on the first floor, and the network points on all floors enter the equipment room, then the number of patch panels is equal to the number of all network points/distribution frame ports in the building (24 ports, 48 ports, etc.), plus a certain margin; if a building has 9 floors and the main equipment room is set on the 4th floor, in order to avoid excessively long cables, there may be sub-equipment rooms on each floor, and There are switching devices. Then the patch panel between the main equipment is equal to the number of network points on the 4th floor/the number of patch panel ports (24 ports, 48 ports, etc.).
The patch panel is the most important component in the management subsystem, and it is the hub to realize the cross-connection of the two subsystems of the vertical trunk line and the horizontal wiring. Patch panels are usually mounted on a cabinet or wall. By installing accessories, the patch panel can meet the needs of UTP, STP, coaxial cable, optical fiber, audio and video.
