A switch is a network device used for electrical (optical) signal forwarding, which can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switches are Ethernet switches. Other common ones are telephone voice switches, fiber optic switches, etc. So, do you know anything about the daily maintenance of switches? Next, let's take a look together!

         1. Daily environmental maintenance

         The switch has relatively high requirements on the temperature and environment of the equipment room. The number of users is large, the energy consumption is high, and the heat emitted is quite large, so the switch needs to operate in a constant temperature and clean environment. If the temperature of the computer room is high, it will be difficult for the machine to dissipate heat, resulting in parameter changes of the switch components, and in severe cases, equipment damage will occur; and if the computer room is too dry, static electricity will occur, threatening the safety of the switch.

         According to regulations, the temperature and humidity of the computer room need to be strictly measured with a thermometer. If necessary, air conditioners, humidifiers and other facilities and equipment can be installed to adjust the temperature and humidity, and fire prevention and dust prevention measures should be taken.

         2. Software and hardware maintenance

         Professional switch maintenance personnel go to work every day to check the functions of software and hardware, record the ambient temperature and humidity of the computer room, and check whether the input voltage and output voltage, current, frequency and other indications are within the normal operating range , Test whether the signals of various audio sources are normal, check whether the spare parts, tools and instruments are complete, fully understand the working conditions of each system, and make records and inspections. Do a good job of comprehensive anti-virus work on servers and maintenance terminals periodically to ensure the safe operation of each server.

        3. Preventive maintenance

        Preventive maintenance is to collect all kinds of data needed by the switch through inspection, measurement, and spot check of the switch, and to classify and analyze the data professionally, so as to propose specific methods and measures for the switch to eliminate hidden dangers. The normal maintenance of the switch needs to be based on preventive maintenance, so as to prevent problems before they happen.

       4. Computer room maintenance system

        In order to ensure the scientific and institutionalized management of the switch machine room, formulate various rules and regulations, on-duty systems, and spare parts management systems for the machine room, and do a good job of recording the original data. The machine room is kept clean and hygienic; security and confidentiality work must also be done . The maintenance rights of switch operators should be set reasonably and effectively to avoid system failures caused by human factors. For the deletion and modification of switch data, the data must be backed up first, so as not to lose the original data and cause inconvenience to the daily data recording work of the switch.

        5. Troubleshooting

        Switches need professional care and maintenance. They often wipe the dust to prevent dust and debris from entering the inside of the switch, causing short circuits and system failures. It is not allowed to replace circuit boards and components for no reason, let alone disassemble the switch without permission. If the indicator light of the switch is always on, it means that the switch has failed. The power supply should be cut off, stop using it, and send it to professionals for maintenance.
