You can manually close the ALARM of the Management port and use this command in juniper: # Set chassis alarm management-ethernet link-down ignore # Commit The light gradually becomes orange. Add another command # Set chassis alarm ethernet link-down ignore # No alert is generated when you set all ports (Note: link-down can detect the port status. If you have set

Suppose there is a Web site, if the laptop as a server, that is, the release of the site and the site's database and a variety of materials are placed on the laptop, and if it is a desktop, the site's release and the site's database and various materials are placed in the desktop computer chassis;For laptops, the notebook itself has the capacity of the hard disk, and for the desktop, its hard disk capacity is in the

, re-boot is equivalent to re-acceleration of the hard disk in the slow state. If this happens, your hard drive will surely be lost.Solution: if you forget to do something after the shutdown, you can just put it down. You must finish it. Please wait for more than one minute and restart the system, or press the hot boot key on the chassis when the power is not disconnected. If none of the above methods are possible, I suggest you fasten a rope on the c

Recently, the customer needs to change the server. The customer sent the purchased server to a very small server. But when I saw it, it was a big, long, wide server, similar to the server in the data center, later, Mr. Mi gave a general explanation: This is a blade server. A blade server is a low-cost server platform that can be inserted with multiple card-type server units in a standard-height rack-mounted chassis to achieve HAHD (High Availability a

be due to heat and deformation, touch the inner wall, emitting noise. The solution is to take a blade in the scratch place gently scraping a few, increase the distance between the fan and the wall, to avoid both friction. Eliminates Hard drive noise The noise from the hard drive may come from its own vibrations, and this is not just about making annoying noises, but about the security of the hard drive. Because the vibration caused by improper installation is likely to damage the

Due to the CPU when the heat generated by conduction to the heatsink to reduce the CPU temperature, and then the fan brought by the cold air blowing the heat away from the heat sink, and the heat of the fan can be transmitted by the size of the heat sink and how much the computer temperature is too high. Generally speaking, the heat sink and the air contact area is bigger, the fan's heat dissipation effect is better, but this kind of argument has certain premise, that is in the case that has eno

solvent is very easy to destroy the special coating, the display of a large discount. Correct way: monitor screen including its shell, can not use alcohol, gasoline, detergent and other solvents, if conditions, please use a special display detergent. If the conditions are not available, you can buy a few bottles of pure water on the market to clean the display screen and the shell. In addition, the screen cleaning special care, do not use ordinary coarse towels, should buy 1~2 block quality be

deliberately put the price of these 3 accessories lower than other counters, let you pick up the feeling of cheap, in fact, in the graphics/motherboard/monitor on every piece can kill you more than 100. or to see the price of the whole machine. Tip Three: Try to find an agent For example, if you want to buy seven rainbow products, try to find agents of the brand stores or counters, or JS will strongly recommend you some high profit but not well-known brands. This time if you still insist on b

Usually appear the temperature is too high have: GPU,CPU, motherboard this 3 kind. (according to the probability of the occurrence of excessive temperature) because the GPU and CPU is the computer's largest power consumption of two

The solution is to take a blade in the scratch place gently scraping a few, increase the distance between the fan and the wall, to avoid both friction. 　　Third, eliminates the hard disk noise The noise from the hard drive may come from its own vibrations, and this is not just about making annoying noises, but about the security of the hard drive. Because the vibration caused by improper installation is likely to damage the hard drive, so the

To build their own mute computer, it is not a very difficult thing, just a few key accessories on a little choice, you can easily achieve.The noise of the computer comes from these aspects: the power supply fan, the CPU fan, the chassis fan, the noise of the video card fan, the noise of the hard drive and the optical drive, and the resonant sound. We hear the computer running "hum" sound, is the superposition of these sounds, to effectively reduce com

thing. IPMI is the abbreviation of intelligent platform management interface (Intelligent platform management interface). It is an industrial standard used to manage peripheral devices in Enterprise Systems Based on Intel structures, the standards are determined by companies such as Intel, HP, NEC, Dell, and supermicro. You can use IPMI to monitor the physical health characteristics of servers, such as temperature, voltage, fan operating status, and

computing. Many companies migrate their services to the cloud, bringing their applications back to the data center deployed internally. However, in the end, the IT department will terminate the process of improving the capabilities of the data center, bring everything to cloud computing, and carefully evaluate the differences between cloud computing provided by service providers. 9. The white box server received the attention of the IT department. Currently, Server products provided by non-bran

There is no way to do this, so you are too lazy to take a photo and COPY the online ready-made materials. I. BIOS settings: Set IP/MAC address in BIOS 1. Press the 2.

Intelligent Platform Management Interface (IPMI) is an open standard hardware management interface specification, which defines a specific method for communication of embedded management subsystem. IPMI information is communicated through the Base Board Management Controller (BMC), which is located on the hardware components of the IPMI specification. There are two main advantages to using low-level hardware management without operating systems: First, this configuration allows Out-of-band serve

Checkpoint algorithms are generally divided into 2 types: non-coordinated and coordinated. In the non-coordinated checkpoint algorithm, each process can independently determine the time to save its own state, the disadvantage is that it is easy to produce domino effect mantle. Each process needs to maintain multiple checkpoint files, wasting a lot of work done and lots of storage space. In the coordination checkpoint algorithm, multiple processes are required to set checkpoints together to ach

A cable with a jack is found in the chassis, and the surface of the slot is marked with some English letters. This is the motherboard control line. In the lower right corner of the motherboard can be found in a row of pins, the needle is also printed next to some English instructions, this is the place to plug the control line. First step: Connect the Power switch control line. The power switch control line is indicated in English as either "powered
