A wiring rack is a very important device in the integrated wiring system, and the larger and more complex the system, the more indispensable the wiring rack.

I. Its function can be summarized as two points:

1. Conversion between wires and cables
For example, large pairs of cables are converted into pairs of telephone lines through a voice wiring rack and distributed to various offices.

Another example is that optical cables are converted into optical fibers through an optical fiber wiring rack and inserted into optical transmission equipment.

2. Hub of cable matrix

 The function of the wiring rack:

The wiring rack is located at the intersection of various subsystems of the integrated wiring system (horizontal wiring subsystem-management subsystem-vertical backbone-equipment interconnection subsystem-building group subsystem) and is the traffic hub of the cable channel. We can adjust the cable channel arbitrarily by inserting the jumper position on the wiring rack, and realize the modularization and flexibility of the integrated wiring system.

II. Wiring racks are mainly divided into the following types according to their functions:

1. Network wiring rack:

Main function: connect network module and switch through RJ45 jumper.

2. Voice wiring rack Main function:

the connection point between a single telephone line and a large pair of cables, mutual conversion.

3. Optical fiber wiring rack Main function:

the connection point between optical fiber and optical cable, mutual conversion.

4. Electronic wiring rack

This device is also widely used in high-end projects and can realize link detection and port detection, which will not be explained in detail here.

III. From this picture we can see two paths:

1. Telephone routing-telephone connects to the voice + network dual-port panel on the wall of the room through a network cable or telephone line, then connects to the network wiring rack in the weak electric well on the floor through a network cable, then connects to the voice wiring rack (110 wiring rack) through duckbill jumper (RJ45-duckbill jumper), then converts to large pair of cables and connects to the voice wiring rack in the computer room, and then connects to the telephone program-controlled switch through duckbill jumper (RJ11-duckbill jumper).

Why does the network cable have to go into the network wiring rack first and then jump to the voice wiring rack? Mainly because the module density of the voice wiring rack is too large, the network cable is too crowded, and can not be fixed in space.

Why use a network cable instead of a telephone line? This way, if voice changes the network, it is more convenient, and the IP phone rises, just use network cable, also is to do reserve for system upgrade.

2. Network routing-the computer connects to the voice + network dual-port panel on the wall of the room through a network cable, then connects to the network wiring rack in the weak electric well on the floor through a network cable, then connects to the RJ45 port (electric port) of the switch through network cable jumper, then comes out of the optical port of the switch and connects to the optical fiber wiring rack through optical fiber jumper, then fuses into optical cable and connects to the optical fiber wiring rack in the computer room, and then fuses into optical fiber and inserts into the core switch.

These two paths realize the function of reaching the external network from the telephone and computer in the room through the internal network built by the integrated wiring. Of course, there are many other kinds of wiring methods, which will not be listed one by one.

IV. Finally, let's talk about how the wiring rack is connected to the switch. You must be talking about the network wiring rack:

This is the back of the wiring rack, the network cable comes over, according to the wire mark on the wiring rack, use the wire cutter to press the eight cores of the network cable into the slot. 2. This is the front of the wiring rack, with RJ45 ports, use a network jumper, one end plugs into the RJ45 port of the wiring rack, and the other end plugs into the RJ45 port of the switch.
