Switches are widely used in information networks. From low-end to high-end, as long as the network is used, switches are basically required. The switch bears the role of connecting various devices on the network, and the role is self-evident, which is very important for the maintenance of the switch. Today, I will introduce the daily maintenance content of the five-point switch and give you a reference.
1. Temperature and temperature are the problems that equipment maintenance can’t avoid. The switch consumes a lot of energy and generates a lot of heat. If the temperature of the equipment room is high, the heat dissipation of the machine will be difficult, resulting in changes in the parameters of the switch components. In serious cases, equipment damage will occur. Happening. Therefore, it is necessary to control the temperature of the switch room, generally between 18 ° C ~ 25 ° C.
2. Humidity has a great influence on the humidity of the switch. Too much dry and static electricity, the air is too humid and there are big problems. Not only will the metal parts rust, but also a short circuit in serious cases. Therefore, it is more suitable to maintain the humidity of the switch room in the range of 40% to 60%.
3. The dust-proof and dust-removing equipment generate an electromagnetic field during operation, which will generate adsorption force to dust. The switch needs to be cleaned regularly to prevent the gray matter from entering the inside of the switch, causing a short circuit and causing a system failure. At the same time, it is necessary to strengthen the hygiene of the switch room and keep the machine room clean and tidy.
4. Supervision, first, does not allow for the replacement of circuit boards and components for no reason, and can not dismantle the switch privately. When the switch fails, it should be handed over to the professional for maintenance; then periodically check the functions of hardware and software and record the environment of the equipment room. In the case of temperature and humidity, whether the indications of input voltage and output voltage, current, frequency, etc. are within the normal operating range, test whether the signals of various sound sources are normal, check whether the spare parts, spare parts, tools, and meters are complete, fully understand Good work of each system, make a record and check; arrange professional switch maintenance personnel to do a comprehensive anti-virus work of the server and maintenance terminal periodically, to ensure the safe operation of each server; to develop various rules and regulations of the computer room To make a record system of raw data, the maintenance authority of the switch operator should be set reasonably and effectively to avoid system failure caused by human factors, and at the same time, work must be done safely and confidentially. 5. Data backup For the deletion and modification of the switch data, the data must be backed up first to avoid losing the original data, which brings inconvenience to the daily data recording work of the switch.
