Does the equipment room subsystem refer to equipment or space place

The equipment room subsystem The equipment room is set up in the appropriate location of each building. , carry out network management and the place where managers are on duty. The equipment room subsystem is composed of building wiring equipment of the integrated wiring system, telephones, data, computers and other host equipment and its security wiring equipment.

Equipment room subsystem: It is a subsystem installed in the equipment room, and the equipment room refers to the place where large equipment is centrally installed. Generally speaking, large buildings will have one or more equipment rooms. Usually, the location of the core switch is the equipment room.

The subsystem of the equipment room is composed of cables, connectors and related support hardware in the equipment room, which interconnects various public system equipment. The main equipment in the equipment room is digital programmed switch, computer network equipment, server, building automatic control equipment host, etc. They can be put together or set separately.

The components of the inter-device subsystem include cables, connectors and related support hardware, which are responsible for various device connections between public systems. The wires in the inter-equipment subsystem are similar to the in-station wiring of the telephone wiring system, which connects the corresponding electrical protection equipment to the building facility location that requires equipment protection.

In the integrated wiring system, () is a subsystem used to connect the management room and the equipment room.

According to the specific functions, the integrated wiring system can be divided into the following six subsystems: work area subsystem, horizontal subsystem, vertical subsystem, equipment room subsystem, management subsystem, building and building complex subsystem.

In the integrated wiring system, the subsystem responsible for connecting the horizontal trunk subsystem and the vertical trunk subsystem is the management subsystem, which is mainly composed of cross-connection, interconnection and I/0.

Vertical trunk subsystem: generally between floors, the management room subsystem and the equipment room subsystem are connected, and it is composed of all wiring cables. ( 5) Device room subsystem: It is composed of cables, connectors, and related supporting hardware in the device room. The system interconnects different hardware in the public system equipment.

Trkline subsystem: It is a subsystem used to connect management rooms and equipment rooms. Generally speaking, it is a network line that connects the access layer switch to the distribution layer (or core layer) switch. Because it usually goes down the weak power well of the building and is perpendicular to the building, it is also called a vertical subsystem.

The work area (terminal) subsystem is connected by the flexible cable of the information socket and the terminal equipment, including assembly, connection, expansion of flexible cable, andThey are built between input and output sockets and equipment terminals, among which information sockets are divided into wall, floor, table and soft base types.

Work area subsystem. Horizontal subsystem. Manage the subsystem. Vertical trunk subsystem. Equipment room subsystem. Subsystem of the building complex.

Please write down the difference and connection between the management subsystem, the equipment subsystem and the in-line subsystem?

Equipment room subsystem Equipment room is the place where in-line equipment is set up, network management and managers are on duty in the appropriate location of each building. The equipment room subsystem is composed of building wiring equipment of the integrated wiring system, telephones, data, computers and other host equipment and its security wiring equipment.

The management subsystem connects the horizontal wiring subsystem and vertical trunk cables of each floor, and is responsible for connecting and controlling other subsystems. It is composed of cross-connection, interconnection and I/O equipment, which can locate communication lines and facilitate the management of communication lines.

The integrated wiring system consists of six subsystems: working area subsystem, wiring (horizontal) subsystem, trunk (vertical) subsystem, equipment room subsystem, management subsystem and building complex subsystem.

Work area subsystem: also known as service area subsystem, it consists of a device connected to a jumper and an information socket. Horizontal subsystem: It consists of a working area information socket module, a module to the floor management room connecting cables, wiring racks, jumpers, etc.

How to design the working area subsystem of the integrated wiring system?

1. The work area subsystem consists of a connection (or soft cable) connecting the terminal device to the information socket. It includes the assembly of flexible cables, connectors and extension flexible cables required for connection, and the connection between the terminal equipment and the input/output (I/O); equivalent to the user cable connecting the telephone and the telephone terminal part in the telephone wiring system.

2. The integrated wiring system consists of seven parts: working area, equipment room, wiring room, wiring subsystem, trunk subsystem, building complex subsystem and management.

3. The information socket and information plug used in the integrated wiring system: at the terminal end of the working area, the 8-pin plug flexible cable is inserted into the socket; at the end of the wiring subsystem, 4 pairs of twisted pair wires are connected to the socket.The 8-pin modular information input/output socket is a standard I/O socket recommended for all integrated wiring systems.

4. System structure design. System structure design should focus on the following 1) Work area configuration design. In the integrated wiring system, a separate area that needs to install terminal equipment is called a working area. The working area is composed of terminal equipment, information sockets connected to the horizontal subsystem and soft jumpers connecting terminal equipment.

5. The structure of integrated wiring adopts modular design and layered star-shaped topological structure.

The integrated wiring system consists of six subsystems, in which the user terminal device is connected to the wiring system subsystem...

The working area (terminal) subsystem is composed of the connection of the flexible cable of the information socket and the terminal equipment, including the assembly, connection and expansion of the flexible cable, and them are built between the input and output socket and the equipment terminal, among which the information socket is divided into wall, floor, table and soft base type.

●Wiring (horizontal) subsystem; ●Trunk (vertical) subsystem; ● Equipment room subsystem; ● Management subsystem; ● Building complex subsystem. Work area subsystem Work area subsystem consists of devices connected to the terminal device between the information socket. Including: information socket, socket box, connection jumper and adapter.

The thermophysical structure of integrated wiring generally adopts modular design and layered star topology.

The following is according to the actual situation of the communityIt is necessary to analyze the six subsystems of the integrated cabling system: the work area subsystem. It is an independent area where terminals need to be placed, that is, a work area. The work area system consists of connecting cables and adapters extending from the information socket of the horizontal wiring system to the workstation terminal equipment.
