Commercial machine internal electromagnetic lock, the normal state of its latch out, the side plate and the chassis firmly locked together, only into the BIOS unlocked, in the electromagnetic lock power, lock the tongue back, in order to open the chassis n
The server Sun Fire B1600 Blade chassis is a 16-socket 3U chassis that installs two integrated gigabit Ethernet switches, two system controllers, and two power supplies. This smart frame is highly reliable and has a server density of five times times the typical single processor 1U server. The horizontally scalable Sun Fire B1600 blades are designed for throughput calculations that allow you to adapt to gro
Memory Bar We must not be unfamiliar, under normal circumstances are not management, but the time is long, because the chassis moved, dust accumulation, there will be a loose memory, computer memory strip How to solve it?
The phenomenon of malfunction:
Phenomenon 1: After the boot, the display is dark, the chassis issued "du-, du-" the long sound.
Phenomenon 2: After power on, the monitor interface sta

# 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

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

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
module, it is a reference implementation of the WSGI server written in pure Python, let's take a brief look at its implementation. Let's start a Web server with the following code:
# Instantiate the server httpd = make_server( 'localhost', # The host name 8051, # A port number where to wait for the request application # The application object name, in this case a function ) # Wait for a single request, serve it and quit httpd.handle_request()
Then, we use the Web server to receive a req

view the uploaded files on the server side, we need to build a server environment. I personally implemented a Python-based REST microserver. In the POST request for processing ArchFlow/upload, I obtained the file from the request and saved it to the local directory. This is the tool server I used in the software architecture. On this basis, the temporary file upload function is implemented.
// Function test:
When the server is started, run the above
