Precautions for managing and maintaining broadband Routers

Enterprises generally use routers in the networking process. As enterprises become increasingly dependent on the network, routers become the lifeblood of the enterprise network, if Enterprise routers are not managed and maintained in a timely manner, after a long period of time, a variety of inexplicable faults will be triggered, and enterprise routers may not work properly, resulting in network interruption, this will cause a lot of inconvenience to enterprise users.

In addition, many enterprise vrouters have a high level of recessive faults. If you don't pay attention to them, it is hard to notice, which is a headache. If the performance of the enterprise vro declines and the network is interrupted, it is very difficult to use a lot of manpower and material resources to remedy the problem. In addition, in case of lightning and other unexpected situations, but there is not enough defense measures in advance for the enterprise router, it may create a good opportunity for users to replace new equipment.

Therefore, we should take precautions against all kinds of problems of Enterprise routers and do a good job of daily management and maintenance in a timely manner, and strive to be prepared. To effectively manage and maintain enterprise routers, we should start from the following aspects.

　　1. Mark and facilitate maintenance

Because there are many computers in the enterprise LAN, and there are many network cables, if a fault occurs, you do not know which line is used. Therefore, you should mark the network cable connecting the computer and the router, on the vro side, you need to specify the host to connect to and on the computer side which port to connect to the vro to facilitate maintenance.

　2. Provide a good working environment for enterprise Routers

In the specification of the enterprise router, the manufacturer has defined the environmental indicators for the normal operation of the router. Therefore, the enterprise should try to provide the enterprise router with a working environment that complies with the environmental indicators specified by the manufacturer, otherwise, the normal operation of the router may be affected, or even the router may be damaged. Generally, you need to pay attention to the power supply voltage, operating temperature, storage temperature, working phase humidity, and storage relative humidity.

Pay special attention to the prevention of moisture and heat. Because enterprise routers are composed of many closely related electronic components, these electronic components may cause short circuit due to moisture, therefore, it is necessary to place it in a dry place. Especially in the plum rain season, we should pay more attention to keeping the working environment of Enterprise routers dry. In addition, the chips of Enterprise routers may emit a large amount of heat during operation. If the chips are not distributed in time, the chip heat may exceed the indicator range, as a result, enterprise routers work abnormally. Therefore, it is best to place the router in a dry and ventilated place. do not cover the router with a decorative cloth or pile up books or sundries around the router. Make the router breathable.

　　3. Anti-electromagnetic interference

During data transmission, data may be affected by various factors. electromagnetic interference is one of the main aspects, for example, if a speaker or radio transceiver is too close to an enterprise router, the network signal may be affected by external radiation. Therefore, try to place the enterprise router in an independent place, far from those devices that may produce electromagnetic interference.

　　4. Do not unplugging the enterprise router during power-on.

When a vro is powered on, do not perform live insertion or removal operations, because such operations can easily cause circuit damage. Although many manufacturers of Enterprise vrouters have taken some protective measures, however, extra attention is still needed to avoid unnecessary damages to the enterprise router.

　　5. Take measures to prevent lightning strikes

The minefield is not uncommon in China. Taking Guangzhou City as an example, an average of 80.3 Thunderstorms can occur each year. As a result, there are also a large number of router users who suffer damage due to lightning strikes. According to the investigation and analysis by engineers of Qno xiaonuo technology, 30% of network equipment faults are directly related to lightning strikes. Although the induction voltage caused by lightning strikes often cannot be completely reimbursed once by the enterprise router, even if it did not cause a network failure at that time, if the enterprise router is frequently affected by the overvoltage, this will easily lead to the aging of router equipment parts, greatly reducing the service life of the old enterprise router is more vulnerable to damage. In this case, if there is no corresponding grounding protection measures, the enterprise router will be easily damaged by lightning strikes and other natural disasters, seriously affecting the stable operation of the network. Therefore, enterprises must take effective measures to prevent lightning strikes. enterprise users can do a good job of equipment grounding devices and install effective lightning protection systems to prevent lightning strikes.

　6. Power Failure Prevention

In the current situation of "Electric panic" everywhere, it is no longer uncommon for the city power to open and limit the power supply for enterprises. In addition, when the power supply process is still interrupted due to insufficient voltage, power supply problems, such as low voltage, such as less than 150 V, or high voltage, such as higher than 260 V, etc, when the power supply is unstable, the router devices in the enterprise network may not work continuously. If an enterprise router often works in an abnormal power supply environment, it will not only seriously affect the service quality provided by the router to the enterprise network, but also greatly shorten the service life of the enterprise router in the long term.

Therefore, to ensure the "stability and longevity" of enterprise routers, the best way is to provide enterprise routers with UPS power systems with excellent and stable performance. The UPS Power Supply can effectively solve power grid problems such as power failure, lightning peaks, surges, frequency fluctuations, sudden voltage changes, voltage fluctuations, frequency drift, voltage drops, and pulse interference, if the UPS power system is configured for the enterprise router, there is no need to worry about voltage instability or sudden power failure will damage the router.

　　7. Try to avoid impact and shock

When an enterprise router suffers an impact or shock, it may cause loose parts of the router equipment, or even directly cause hardware damage. Therefore, when the Mobile Enterprise router is re-installed, it is recommended that you set the router to a specific rack. This not only avoids the impact and shock on the router, but also prevents the cable from falling off and ensures normal communication between the enterprise router.

8. effectively prevent enterprise routers from being infiltrated by static electricity

When electrostatic discharge occurs, it is easy to cause hardware damage to the enterprise router. With the continuous improvement of the chip technology of network equipment, the speed and function of the chip have been improved, but the chip has become more fragile. A relatively high electrostatic voltage can penetrate the transistor, and a relatively large electrostatic current can melt the connection. Static Electricity is everywhere, and static electricity is the invisible killer of network equipment, therefore, to effectively maintain enterprise routers, we must take proper measures to prevent static electricity. The specific practices include the following:

1) Enterprise routers should maintain good contact and have reliable grounding devices.

2) For enterprises in dry climate areas (such as enterprises in northern regions), appropriate humidifier should be used in dry season to maintain a certain humidity of the air, to avoid the accumulation of static electricity on equipment, office equipment, and enterprise network users.

　　9. Keep Enterprise routers away from dust

The dangers of dust on Enterprise routers cannot be ignored. If there is too much dust on the equipment and the equipment is not cleaned up in a timely manner, the enterprise network may encounter some inexplicable faults, if it is light, it will lead to poor contact with the interface. If it is heavy, it may burn down the chips in the enterprise router. It can be seen that the dust removal effort of Enterprise routers is also very important and cannot be ignored or wrong.

　　10. Pay attention to security

In actual use of enterprise routers, in addition to correct installation and settings, you must set a management password and keep it confidential. Do not allow others except the Administrator to access the vro, do not allow others to configure the vro at will.

　　11. Regular data backup of Enterprise Routers

To prevent accidental network paralysis and the loss of the original configuration, the configurations of the enterprise router should be backed up on a regular basis. Before performing a backup, you must first create a tftp SERVER. This is relatively easy. Select a PC and run the cisco tftp server software. Then, back up the vro configuration to the backup server. The procedure is as follows:

1) Telnet to the vrotelnet to be backed up, telnet xxx. xxx (Server IP address)

2) check whether the router is connected to the tftp server. ping xxx. xxx (IP address of the tftp server)

3) Use copy running-config tftp to back up the configuration file to the tftp server.

4) enter the IP address and target file name of the tftp server as required by the command and confirm it.

　　12. Update System Software of Enterprise routers frequently

Like a network operating system, the operating system of an enterprise router also needs to be updated from time to correct programming errors, software flaws, cache overflow, and other problems. Because the system software of a vro usually has many versions, and each version supports different functions. If the current software version does not support a certain function, some of the functions of the enterprise router will be lost. If the corresponding software upgrade is performed, the function will be restored. Therefore, you often need to query the current enterprise vro update and operating system version from the vro manufacturer. If a new version is found, update it as much as possible.
