1、 Environmental Management: Building a Stable Operating Foundation

1. Temperature and Humidity Control
   • temperatureIt is recommended to maintain the temperature in the computer room at18℃-27℃To avoid equipment overheating and damage caused by high temperatures or condensation short circuits caused by low temperatures.
   • humidityHumidity control within40%-70%To prevent static electricity generation (too dry) or circuit corrosion (too wet). Real time monitoring can be achieved through a temperature and humidity meter, and if necessary, air conditioning, humidifiers, or dehumidifiers can be installed for adjustment.
   • DustproofRegularly clean the computer room and cover the equipment with dust-proof nets to prevent dust from blocking the heat dissipation holes or entering the internal circuits.
2. physical protection
   • Lay anti-static flooring and apply anti-static treatment to walls to reduce the damage of static electricity to equipment.
   • Ensure good ventilation in the computer room to avoid performance degradation or malfunction of equipment due to poor heat dissipation.

2、 Hardware maintenance: ensuring the physical health of equipment

1. regular cleaning
   • deep cleaning: Every3-6 monthsUnplug the power, clean the circuit board and fan dust with a soft bristled brush, and then blow the heat dissipation holes and gaps with a compressed air tank.
   • Fan maintenanceIf the fan makes abnormal noise during rotation, clean it and add lubricating oil; If damaged, replace it promptly to avoid heat dissipation failure.
2. Component Inspection
   • Regularly inspect power modules, fans, ports, and other components, and replace them promptly if aging or damage is found.
   • Check if the cable connections are loose, especially the network cables and fiber optic interfaces, to ensure good contact.
3. Cable management
   • Unified cable standards (such as using different colors for different services) to avoid dead bends or entanglement, reduce signal interference and transmission loss.
   • each2-3 yearsReplace aging network cables to reduce network failures from the source.

3、 Software management: Ensure stable operation of the system

1. Configure backup and recovery
   • Export configuration files through the command line or management interface every month, save them to a portable hard drive or cloud drive, and label the file name with a date (such as "20241223- Switch Configuration").
   • Extra backup before important occasions (such as system upgrades and configuration changes), and quick import and recovery in case of chaotic configuration.
2. Firmware and patch updates
   • Regularly check firmware updates released by manufacturers, fix known vulnerabilities, and improve performance.
   • Install security patches to prevent device attacks or data leaks.
3. access control
   • Restrict physical and logical access permissions, allowing only authorized personnel to manage devices.
   • Use a strong password strategy and regularly change passwords to avoid the risk of weak passwords.

4、 Daily monitoring: Real time monitoring of equipment status

1. Inspection of indicator lights
   • Daily check power lights, system lights, and port indicator lights:
     • The power light is not on: check the power cord or socket.
     • System light abnormality: Log in to the management interface to view logs and troubleshoot system errors.
     • Port light not on: Re plug and unplug the network cable, replace the network cable, or check for port faults.
2. log analysis
   • Enable logging function to track system events and exceptions (such as port jitter and packet loss).
   • Identify the root cause of faults through log analysis, such as broadcast storms, virus attacks, etc.
3. traffic monitoring
   • Log in to the management interface to view port traffic statistics. If the traffic on a certain port suddenly increases (3-5 times higher than usual), it may be due to device poisoning or large file downloads, and it needs to be dealt with in a timely manner.

5、 Performance tuning: improving network efficiency

1. Traffic planning
   • Reasonably allocate bandwidth, avoid congestion, and ensure priority for critical applications such as video conferencing and databases.
   • Configure QoS (Quality of Service) policies to optimize bandwidth usage.
2. Redundant design
   • Implement multi-path load balancing, backup routing, etc. to improve network reliability and availability.
   • Key equipment adopts dual power redundancy to avoid single point failures.

6、 Security protection: resist external threats

1. Encryption Protocol
   • Disable Telnet (plaintext transmission) and use SSH (encrypted transmission) for remote management to ensure data security.
   • Configure Console port local management as the 'last straw' for fault recovery.
2. security policy
   • Enable Access Control List (ACL) to restrict unauthorized access.
   • Regularly scan servers and maintain terminals to prevent viruses from spreading to switches.

Suggested maintenance cycle

• dailyCheck indicator lights, network connectivity, and log errors.
• weeklyCheck port status, clean dust, and monitor traffic.
• monthlyDeep cleaning, backup configuration, and performance evaluation.
• quarterlyCheck firmware version, optimize VLAN partitioning, and update security policies.
