Some common problems in switch operation and maintenance
With the rapid development of information technology, as the carrier of information circulation, switch is one of the most widely used network equipment, its role is self-evident. Therefore, in Nissan's use, we should pay attention to the maintenance of the core equipment, such as the switch, so as not to cause failure. What problems should be paid attention to in switch operation and maintenance?
1. Daily environment maintenance
The requirement of the switch for the temperature and environment of the machine room is relatively high. With large number of users, high energy consumption and considerable heat emission, the switch needs to operate in a constant temperature and clean environment. If the temperature of the machine room is high, it will cause the difficulty of heat dissipation of the machine, which will cause the change of the parameters of the switch elements, and even the damage of the equipment in serious cases; if the machine room is too dry, it will produce static electricity, which will threaten the safety of the switch.
According to the regulations, the temperature and humidity of the machine room need to be measured by thermometer strictly. If necessary, air conditioner, humidifier and other facilities and equipment can be installed to adjust the temperature and humidity, and fire and dust prevention measures should be taken.
2. Software and hardware maintenance
The professional exchange maintenance personnel shall check the functions of software and hardware every day, record the ambient temperature and humidity of the machine room, check whether the input voltage and output voltage, current, frequency and other indications are within the normal operation range, test whether the signals of various sound sources are normal, check whether the spare parts, tools and instruments are complete and fully understand Good working condition of each system, record and check. Periodically do a good job in the overall antivirus work of servers and maintenance terminals to ensure the safe operation of each server.
3. Preventive maintenance
Preventive maintenance is to collect all kinds of data required by the switch by means of inspection, measurement and spot check, and to classify and analyze the data professionally, so as to put forward specific methods and measures to eliminate the hidden dangers of the switch. The usual maintenance of the switch needs to be based on preventive maintenance, to do a good job of prevention in advance.
Professional switch operators are required to use the terminal in strict accordance with the operation manual, first check the system software configuration or system software to avoid executing the wrong command in daily work, strictly check whether the I / O equipment is in normal state, especially the inspection of floppy disk drive, and timely modify the wrong data. The software tape brought by the following switch equipment must be kept properly. If the switch system breaks down, it can be reinstalled and used. In daily work, professional maintenance personnel are good at finding the potential fault of equipment, finding out the main cause of the possible fault and eliminating the hidden danger.
4. Computer room maintenance system
In order to ensure the scientific and systematic management of the switch room, various rules and regulations, duty system and spare parts management system of the room shall be formulated, the original data recording system shall be well done, the room shall be kept clean and sanitary, and the work of safety and confidentiality shall be well done. The maintenance authority of switch operators shall be set reasonably and effectively to avoid system failure caused by human factors. For the deletion and modification of switch data, the data must be backed up first to avoid the loss of the original data, which brings inconvenience to the daily data recording work of the switch.
5. Fault maintenance
The switch needs professional personnel to carry out care and maintenance, often wipe the dust to prevent the dust layer sundries from entering the switch, resulting in short circuit and system failure. It is not allowed to replace the circuit board and components without any reason, let alone dismantle the switch without permission. If the indicator light of the switch is on for a long time, it indicates that the switch is in fault, the power supply should be cut off, the switch should be stopped and handed over to the professional for maintenance.
Because of the variety of switch faults, some of them are obvious, which can be identified at a glance, processed and maintained. Some of them are not so clear and clear, which requires specific analysis.
Therefore, as a professional exchange maintenance and operation personnel, in the daily work, we should constantly strengthen the update and expansion of theoretical knowledge, do a good job in integrating theory with practice, and do a good job in the daily maintenance and management of the exchange, diligently find the root cause of the problem and find the best way to solve the problem, so as to continuously improve our own and better finish Become the work of network management.
