Maintenance and disassembly of server hardware system

With the phrase "It’s harder to keep the world hard to keep the world", server maintenance is like "shouting the world"! A little mess will cause the whole network to be paralyzed. Maintaining the server requires a thorough understanding of the server's hardware system, operating system, and application software system. It is also a system engineering. The maintenance of the hardware system is in server maintenance. The most basic and important part is also a never-ending job.

Working papers


maintenance of server hardware systems of the simplest is to modify the server, add or upgrade certain components. To this end, this article starts with the disassembly of the server.

with the server component prices gradually lower, using only its standard configuration work becomes somewhat cost-effective, while the server itself also provides users with the majority of headroom, so more and more users choose to Server configuration is upgraded for better operational efficiency. For example, to support multi-core motherboards to increase CPU, memory hard disk expansion, add Gigabit optical port network card, install SCSI card to improve data read and write speed, install RAID card to enhance data fault tolerance. In addition, some server components such as power supplies and fans may experience aging or malfunction due to uninterrupted operation for a long time, which requires us to replace them in time.

Notes

correct operation


off power to a server has been configured, its opening and closing operation is very simple However, if the operation method is not correct, it may cause unnecessary damage to the equipment. Therefore, we need to give a detailed introduction to the boot and shutdown of the server.

Shutdown operation:

1. Shut down the operating system.

2. turn off the system.

3. Power off peripherals (such as disk arrays, tape libraries, etc.).

4. Turn off the power of other equipment and cabinet power.

5. Turn off the main power.

Power On:

1. Turn on the main power.

2. Turn on the power of the computer cabinet.

3. Power on external devices (such as disk arrays, tape libraries, etc.).

4. After the external device self-test is completed, finally turn on the power of the host.

Comprehensive prevention of static electricity


Although the computer works on electricity, static electricity can cause fatal damage to the computer, especially permanent damage to the motherboard chip. . There are many reasons for static electricity generation: various power supply devices may generate static electricity, computer CRT monitors may generate static electricity, and mobile phones and walkie-talkies in operation may generate a large amount of static electricity in the surrounding space. This requires us to pay special attention to static electricity interference and comprehensive prevention. .

1. try to make the server and its peripheral equipment grounded.

2. If the equipment is not grounded, when we want to contact with the inside of the card, you should use ground wire or other discharge facilities be discharged.

3. When the device is operated, antistatic should wear gloves, if not, to let go of their static electricity can touch at the outer metal enclosure.
