Several points to pay attention to the maintenance and management of the integrated wiring system:
1. Beware of Harmonics Occasionally, in the data center room during the peak of network operation, there may be unstable network operation. This phenomenon is caused by frequent data transmission between the server and the terminal. Occasionally, the data update speed becomes slower and sometimes intermittent. Similarly, routing switching equipment sometimes "bursts" abruptly. The data transmission is temporarily blank. It seems that the network has been interrupted. After investigation, the real culprit behind the scene is the harmonic wave. The root cause is the unreasonable layout of the power supply system of the enterprise's engine room.
The first thing to do is to periodically test the power harmonic content and the network error rate. Don't take it lightly when an error frame is found. In addition, the number of workstations powered by all the way to the power supply should not exceed 30 units, otherwise the power supply area should be re-delineated as the network segment. In order to avoid excessive accumulation of internal harmonic power, exceeding the allowable range of the equipment. If the reliability of the network is very high, or for some very critical networks, it is recommended that you select the main network devices such as servers and routers to be powered by separate UPSs during network planning and design to eliminate the harmonics of other power supplies. The impact of waves on it.
2. The erosion of the air on the link The network link is leaking 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, optical fiber links are often overlooked by people. Because of long-term storms in the air, they are extremely eroded and contaminated by water vapor, dust, etc. in the air. Under normal circumstances, this type of network failure is more difficult to determine and locate, and is affected by environmental factors.
To prevent the occurrence of such failures, we must first improve the cabling of the equipment room, isolate the air from the link, and pay special attention to the joints of the links. This is the most likely cause of erosion. Secondly, to improve the environment of the computer room, in fact, the requirements of the network equipment on the environment are more demanding. If conditions permit, the parameters such as temperature, humidity, and wind speed in the equipment room are monitored and adjusted according to the conditions. The final periodic overhaul is also essential, and at least two inspections of this kind are to be carried out at least once a year to replace the damaged link.
3. Records are indispensable Some engine room management personnel are very good in technology but lack good habits. They are arbitrarily random in the management and maintenance of the equipment room. Not only is the number of equipment in the equipment room, operating conditions, network layout, etc. not well understood, and there is no habit of recording after network configuration. The gaps in these management processes are fully exposed in the event of a network failure during troubleshooting. The usual situation is that administrators are in a hurry but cannot locate faults, and work efficiency is very low.
The manager of the equipment room first records the equipment and records the equipment in the equipment room. These records should strive to be exhaustive. It is advisable to carry out classified archive recording in the form of a table, which may include the following contents: installation time, maintenance record, operation status, shelf life, and the like. Followed by the configuration record, the corresponding configuration information of the device is recorded. Such as connection port, account, password and so on. It is best to picture the network topology of the entire computer room and then make changes according to the adjustment of the layout. There are also some records that are necessary, that is, maintenance records of the computer room network failure. These records should be exhaustive, including time to failure, symptoms, exclusion methods, and causes of errors. In practice, these records are often ignored by some managers. In fact, these records are very helpful for network troubleshooting later.
4, lighting system can not be ignored Lighting system is an indispensable part of the computer room construction. The computer room lighting system is different from the general factory lighting, but also different from the general office, conference room and home lighting. Computer room lighting, in addition to the general lighting should have the performance, there are their own special requirements. In particular, some computer rooms use a fully enclosed structure. Only artificial light sources and no natural light sources can be used in the room. In this case, the good lighting of the room lighting system is particularly important. The good lighting quality of the engine room not only affects the working efficiency and physical and mental health of computer operators and maintenance personnel, but also affects the reliable operation of the computer.
A standard room should have at least two lighting systems. The first is general lighting, natural light sources from external celestial bodies and artificial lighting, ie, various lighting devices. The requirements that should be met for general lighting are: soft light, suitable for the physiological needs of the human body, and can not interfere with the computer's interference due to the interference generated by the light source. In addition, accident lighting must be prepared. In some special cases, when the normal lighting is extinguished due to a fault, the accident lighting can provide convenience for the staff to handle the fault and transfer the equipment in time.
5, beautiful and orderly cabling Many computer room wiring clutter. Normally, the manager of a computer room is convenient or does not recognize the importance of wiring, so most of them will not spend a lot of energy on this. The usual situation is that dozens of lines are tangled together like a mess. This kind of wiring is not only unsightly but also has obvious drawbacks. The maintenance of the network does not change the working efficiency, and the electromagnetic interference between the lines causes the performance of the network equipment to decline and the stability is reduced. In particular, it brings great security risks.
How to do a good job of the computer room network wiring? First of all, we must do a reasonable planning and design before wiring, do a full investigation and study, visit the computer room to collect the relevant wiring information, it is best to draw drawings and then wiring. Second, purchase the appropriate integrated wiring equipment, corresponding wiring tools and auxiliary tools. If conditions permit, purchase cable ducts, galvanized pipes, etc. to regularize the cable. In addition, it is strongly recommended that the unreasonable wiring room must be replanned and implemented. There is also such a situation that when the computer room is completed, the wiring is very neat and reasonable. Due to poor management and maintenance, it is very messy and all the usual good habits are very important.
The management and maintenance of the equipment room is very complicated and hard work, and of course it is also very important work. Starting from the details, no dead ends or blanks are left. In fact, we can do it once and for all. Helian Electronics has been focusing on technology and quality for 16 years, providing customers with comprehensive and professional services and technology, and tailoring reasonable integrated wiring solutions.
Comprehensive wiring system maintenance management five major points
The integrated wiring system is a set of information transmission channels for computers, communication facilities and monitoring systems that are used in buildings or between buildings. It connects voice, data, images and other devices to each other, and at the same time enables the above devices to connect with external communication data networks. Its core is "integration", that is, each weak system can use integrated wiring system for information transmission.
