Before introducing enterprise servers, let's take a look at the Integrated Network Cabling Technology of enterprises. Then we fully introduced the production of Network cables and integrated enterprise network cabling. For servers, more reasonable Optimization of enterprise integrated network cabling can play a very good role in server maintenance.

Server maintenance is indeed a very complex and important task. At the same time, server maintenance involves a wide range of technologies: Server Security, hardware maintenance, software maintenance, etc. Hardware maintenance and software play an equally important role in the hardware system of servers and the entire network environment. It can be seen that server maintenance is extremely important, and the key is how to provide better solutions for enterprises, in view of one aspect of server maintenance, the company's integrated network cabling explores how enterprise users can better maintain servers.

Network cable Creation

Compared with small enterprises, it is quite simple to set up a network to implement the Internet function. It can meet their business network application needs only by connecting a vro with a vswitch. For the network construction of large and medium-sized enterprises, the entire network structure requires the server as the background application system to provide network support, the most basic network for enterprise servers to build a network requires a network cable as the connection medium. network cable production is an important step for building a network, any unqualified network cable will directly affect the use of the network, resulting in network failure or slow network speed. I will briefly introduce how to create a standard network cable.

There are two standards for twisted pair practices:

EIA/TIA568A and EIA/TIA568B;

There are two main connection methods:

Straight-through and cross-Cable;

For EIA/TIA-568A standards, the twisted pair wires are distinguished by electrical characteristics:

Category 3, category 4, Category 5, and most commonly used Category 3 and Category 5 lines in the network. Currently there are more than Category 6 lines.

Currently, the most common enterprise Integrated Network Cabling Standards include:

That is, the T568A standard and the T568B standard.

The line sequence described in T568A is from left to right:

1-white green, 2-green, 3-white orange, 4-blue, 5-white blue, 6-orange, 7-white Brown, 8-brown;

The line sequence described in T568B standard is from left to right:

1-white orange, 2-orange, 3-white green, 4-blue, 5-white blue, 6-green, 7-white Brown, 8-brown;

The T568B standard network cable is usually used in enterprise application networks.

Finally, after both ends of the crystal head are completed, you can use the wire Tester for testing. If the eight indicators on the tester are green flashing in turn, it proves that the network cable has been successfully created, we believe that qualified network cables will facilitate future network maintenance.

Enterprise Integrated Network Cabling
Enterprise integrated network cabling should not only start from the actual needs of the enterprise, but also plan and design the network based on the enterprise's cost budget. At the same time, it must support network equipment, servers, and other equipment, it is important for network administrators to make proper network layout and wiring for data centers and office locations. The author briefly introduces the issues that need to be considered in the networking layout.

◆ Network cable selection
Wiring is an important link connecting the network access layer, aggregation layer, switching layer, and network nodes. Dedicated channels are recommended for enterprise integrated network cabling, and do not mix cables with power cables, air conditioning lines, and other radiation lines. In addition, you can select cat5e shielded twisted pair wires to maximize network performance.

◆ Network Layout Planning and Design
It is best to place network devices in the center of a node, which not only saves the cost of integrated network cabling, but also improves the overall network performance and network transmission quality.

Currently, most network devices use rack-mounted structures, such as switches, routers, and hardware firewalls. They are all placed in cabinets designed according to international standards. This not only makes the device occupy the minimum space, but also facilitates connection and management with other network devices, in addition, the IDC will also look neat and beautiful.

The network layout of enterprises should take into account the devices. In general, network devices such as switches, routers, firewalls, Encryptors, and network communication devices such as optical terminals and modems are placed in network cabinets; the width of the server cabinet is 19 inch. There is a detachable sliding drag frame in the Cabinet based on the U Height. You can adjust the height flexibly according to the height of your server, to store servers, hubs, disk cabinets, and other devices. After the server is placed, all its I/O lines are drawn from the rear of the Cabinet, and are uniformly placed in the cable slot of the Cabinet, with the network cable label attached, this facilitates effective management in the event of network faults.

In the network layout, each cabinet has a certain amount of space to facilitate the expansion of network equipment and server equipment in the future. In addition to network wiring, the enterprise integrated network wiring cabinet may also have the ability to deploy telephone lines, therefore, leave some space in the cabinet. For cabinets, adequate cable channels must be provided to ensure that the Network cables can be accessed from the top and bottom of the cabinets. In addition, this reduces the space occupation of cables, ensures that the equipment installation, adjustment, and maintenance are not affected by wiring, and ensures that the heat dissipation flow is not blocked by cables. In the case of a fault, allows you to quickly locate device cabling.

Reasonable and perfect enterprise integrated network cabling will not only have a profound significance for server maintenance in the future, but also have a profound impact on enterprise costs, effective enterprise integrated network cabling can reduce layout changes such as upgrade and expansion in the future and facilitate network administrators to maintain equipment and systems more effectively. In addition, the integrated network cabling of enterprises has more advantages in the heat dissipation of equipment rooms, reflecting the concept of green environmental protection and simplified IT.
