Some of the most popular fabric wrap protection body fitness gym accessories include wrist wraps, knee wraps, elbow wraps, and ankle wraps. These accessories are designed to provide compression and support to the joints, helping to prevent injuries and reduce pain and discomfort.
Wrist wraps are commonly used during weightlifting exercises that put a lot of strain on the wrists, such as bench press, overhead press, and deadlifts. Knee wraps are used to support the knees during squats, lunges, and other leg exercises. Elbow wraps are used to provide support and compression to the elbows during exercises that put a lot of stress on the joints, such as bicep curls and tricep extensions. Ankle wraps are used to provide support and stability to the ankles during exercises that require a lot of jumping and lateral movement, such as plyometrics and agility drills.
Network cabinet jumper and distribution frame function and use
When it comes to network cabling, when it comes to network cabinets, everyone is familiar. Today, let's learn together what exactly is the patch panel, what is the jumper, what is the cable manager, and what they are used for.
First, what is the jumper
The so-called jumper frame is composed of flame-retardant modular plastic parts, which are equipped with a number of toothed strips for end-wiring pairs. The 788J1 special tools can be used to “punch†the wire pairs in sequence to the jumper frame. The voice trunk cable and the voice horizontal cable are terminated. Common specifications are: 100 pairs, 200 pairs, and 400 pairs.
Why use a telephone jumper
Generally used in the computer room with a program-controlled phone. After the telephone line is connected to the program control machine, it is the line of the extension number that is received from the program control machine. Then snap all of these lines onto the jumper, then take the line from the outlet to your extension number, and place the number on the patch panel. There is a problem with the phone. It is easy to look at the label on the patch panel when you are overhauling, and then find the line along the line. Don't use a jumper to make you die. The lines are the same as the chaotic group.
The role of the jumper
1. It can reduce the loss of network device interfaces such as switches.
For example, network administrators often plug and unplug lines and test lines. This will cause the switch results to loosen for a long time. If the connection is not tight, you need to use a jumper to use the cable from the work area. Installed on the jumper, and then make a small network cable - commonly known as jumper, connect the jumper to the switch, so that network administrators only need to unplug the RJ-45 at the end of the jumper. The interface is here. The jumper is much cheaper than the interface card on the switch.
2, wiring is regular, neat, beautiful, professional
Appearance, the jumper looks like a row of fish bones, also known as the fish skeleton. Usually used by telephone connection. The role of the jumper is to connect high-density voice data cables, providing convenient and fast termination wiring. The jumper can be used for both wall mount and vertical cabinets. The jumper has a wide range of functions and is suitable for high-speed applications in all voice communication systems, multimedia, etc.
The jumper frame generally cooperates with the 110 connection block to function as a jumper. There are many types of jumpers. Currently, there are 50 pairs and 100 pairs of legs and legs without legs. The connecting blocks are available in 4 pairs and 5 pairs. The role of the jumper is also related to the type of jumper. Different types of jumpers have different functions. Users should select the appropriate jumper when wiring.
Cable manager
Second, what is the distribution frame
A device used for end-user lines or trunks and capable of making a connection to them. The patch panel is an important component in the management subsystem and is the hub for cross-connection of two subsystems, vertical trunk and horizontal cabling. Patch panels are usually mounted in cabinets or walls. By installing accessories, the patch panel can meet the needs of UTP, STP, coaxial cable, fiber optics, audio and video. Patch panels commonly used in network engineering include twisted pair patch panels and fiber patch panels. According to the location and use, it is divided into two categories: main distribution frame and intermediate distribution frame.
Use of patch panels
The location 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 (Super Category 5 or Category 6 cable) enters the equipment room and then enters the distribution frame. The line is placed on the module of the distribution frame, and then the patch panel and switch are connected by jumpers (RJ45 interface). .
In general, the patch panel is a device for management. For example, if there is no patch panel, the information point of the front end is directly connected to the switch, and if there is a problem in the cable, it is faced with rewiring. 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 the jumper can be replaced to achieve better management.
If there is only four floors in a building, the main equipment is set on one floor, and the network points of all floors enter the equipment room. The number of distribution frames is equal to the number of all network points/distribution frames in the building (24 ports, 48 ports, etc., plus a certain margin; if a building has 9 floors and the main equipment is set at 4 floors, then in order to avoid the cable length, it is possible to have a sub-equipment between each floor, and There are switching devices. Then the distribution frame between the main devices is equal to the number of network points on the 4th floor/the number of distribution frame ports (24 ports, 48 ​​ports, etc.).
The patch panel is an important component in the management subsystem and is the hub for cross-connection of two subsystems, vertical trunk and horizontal cabling. Patch panels are usually mounted in cabinets or walls. By installing accessories, the patch panel can meet the needs of UTP, STP, coaxial cable, fiber optics, audio and video. Patch panels commonly used in network engineering include twisted pair patch panels and optical patch panels.
What is the difference between the jumper and the patch panel?
The jumper is a high-density voice data cable connection that provides convenient and fast termination wiring. The jumper can be used for both wall mount and vertical cabinets.
As the core product of the integrated wiring system, the patch panel plays the role of flexible transfer, flexible distribution and comprehensive management of transmission signals. It's a specification, it's also a neat, it doesn't look messy, it also makes the line changes easier.
