Comprehensive wiring system maintenance management attention points

The integrated wiring system is a set of information transmission channels pre-set for computers, communication facilities and monitoring systems within buildings or between buildings. It connects devices such as voice, data, and images to each other, and enables the above devices to be connected to an external communication data network. Its core is "comprehensive", that is, each weak current system can be transmitted by integrated wiring system.

Several points to note about the maintenance and management of integrated wiring systems:

1, vigilant harmonics

Sometimes the data center computer room will experience unstable network operation during the peak network operation. The data transmission between the server and the terminal is frequently wrong. The data update speed is occasionally slow, and sometimes it is intermittent. Similarly, routing switching devices sometimes suddenly "shock", data transmission is temporarily blank, it seems that the network has been interrupted. After investigation, the real murder behind the scenes is harmonics, and its root cause is that the power supply system layout of the enterprise computer room is not reasonable enough.

First of all, the power harmonic power content and network error rate should be tested regularly. When you find the error frame, don't take it lightly. In addition, the number of workstations that can be driven by one power supply is recommended not to exceed 30. Otherwise, the power supply area should be redefined as the network segment is divided. In order to avoid excessive accumulation of internal harmonic power, exceed the allowable range of the device. If the network reliability requirements are very high, or for some very critical networks, then it is recommended that you select the main network equipment, such as servers, routers, etc., when network planning and design, choose to be powered by a separate UPS to eliminate the harmonics of other power supplies. The impact of waves on it.

2. Air etches on the link

The network link leaks in the air. If the temperature, humidity, and wind speed of the equipment room do not meet the requirements, the link will be eroded. For example, fiber optic links are often overlooked by everyone. Due to long-term leakage in the air, they are very eroded and polluted by water vapor and dust in the air. Under normal circumstances, such network faults are more difficult to judge and locate, and are more affected by environmental factors.

To prevent such failures, first improve the wiring of the equipment room, and do a good job of isolating the link from the air. Pay special attention to the joints of the links. This is the most likely place for corrosion. Secondly, we must improve the environment of the computer room. In fact, the environmental requirements of network equipment are more demanding. If conditions permit, monitor the temperature, humidity, wind speed and other parameters of the equipment room, and then adjust according to the situation. Final periodic inspections are also necessary, and at least two such tests are performed at least one year to replace the damaged link.

3, the record is indispensable

Some computer room management personnel are very good in technology but lack good habits. They are too random in the process of computer room management and maintenance. Not only does not know enough about the number of devices in the equipment room, operation, network layout, etc., and there is no habit of recording after network configuration. The gaps in these management processes are exposed in the process of troubleshooting in the event of a network failure. The usual situation is that the administrator is in a hurry but can't locate the fault and the work efficiency is very low.

The manager of the equipment room, first of all, records the equipment and records the equipment in the equipment room. These records should be exhaustive. It is best to classify and archive records in the form of a table, which can include the following contents: installation time, maintenance record, operating status, shelf life, and the like. The second is the configuration record, which records the corresponding configuration information of the device. Such as connection port, account, password, etc. It is best to plot the network topology of the entire computer room and then make changes according to the layout adjustment. There are also some records that are necessary, which is the maintenance record of the network failure of the equipment room. These records should be exhaustive, including downtime, symptoms, troubleshooting, and cause of errors. In actual work, these records are often ignored by some managers. In fact, these records are very helpful in troubleshooting the network.

4, the lighting system can not be ignored

Lighting system is an indispensable part of the construction of computer room. The lighting system of a computer room is different from the lighting of a general factory, as well as the lighting of general offices, conference rooms, and homes. The lighting of the computer room, in addition to the performance of general lighting, has its own special requirements. In particular, some computer rooms use a fully enclosed structure, and only artificial light sources can be used in the equipment room without natural light sources. In this case, the good ring of the computer room lighting system is particularly important. The quality of the computer room lighting is good, which not only affects the work efficiency and physical and mental health of computer operators and maintenance personnel, but also affects the reliable operation of the computer.

A standard computer room should be equipped with at least two lighting systems. The first is general lighting, natural light sources from outside celestial bodies and one type of artificial lighting that is a variety of lighting equipment. The requirements for general lighting are: soft light, suitable for the physiological needs of the human body, and can not affect the interference of the computer due to interference from the light source. In addition, be sure to prepare for accident lighting. In some special cases, when the normal lighting is extinguished due to the fault, the accident lighting can facilitate the staff to handle the fault and the equipment transfer in time.

5, the wiring is orderly and beautiful

The wiring of many computer rooms is messy. Usually, the manager's diagram of the equipment room is convenient or does not recognize the importance of wiring, so most will not spend a lot of energy on it. The usual situation is that dozens of wires are entangled together like a mess, and such wiring is not only unsightly but also obvious. Network maintenance does not work inefficiently, and electromagnetic interference between lines causes network equipment performance degradation and stability degradation, especially bringing huge security risks.

How to do the network cabling of the computer room? First of all, before the wiring, we must do a reasonable planning and design, do a full investigation and study, visit the computer room to collect relevant wiring information, it is best to draw the drawings and then wiring. Second, purchase appropriate integrated wiring equipment, corresponding wiring tools and auxiliary tools. If conditions permit, purchase cable management tanks, galvanized pipes, etc. to regulate the network cable. In addition, it is strongly recommended that the equipment room with unreasonable wiring must be re-planned and implemented. There is also the case that the cabling is very neat and reasonable when the equipment room is completed. Due to poor management and maintenance, it is very messy. All the usual habits are very important.

The management and maintenance of the computer room is very complicated and hard, and of course it is also very important work. Starting from the details, leaving no dead ends, blanks, in fact, can also achieve a certain degree of once and for all.
