In this era of high computer penetration, many people like to build their own computers, rather than take the assembly of computer configuration to the computer city directly to buy the assembly machine back, if it is directly to the merchant installed, directly to the assembly machine to bring back, oneself is lost a experience DIY machine fun opportunity, Some users may be afraid of their own installation is not good, do not worry, take a look at our steps to teach you how to assemble a comput

layer traffic must be used, that is, the stateful 4 ~ Layer-7 traffic. Separate 4 ~ Layer-7 Traffic testing tools are available on the market, including IXIA IxLoad. One of these tools is to directly connect to the sending and receiving ports of the devices under test, there is no complex and real route table. In order to fully verify the performance of the routing device with the deep packet detection function, the route table and 4 ~ Layer-7 statef

range of security threats and secure, unsecured communications, personal terminals, corporate networks, and carriers install or deploy a wide variety of security software and devices to protect against threats from hosts and networks or secure encrypted communications, including firewalls, ids,ips, spam gateways, Proxy servers, IPSec gateways, and SSL VPN gateways. However, the introduction of these devices will have a certain impact on the performance of the network. A number of manufacturers

What about desktop images flashing? Desktops have advantages that laptops cannot match. The desktop chassis has been widely used because of its large space and good ventilation conditions. The desktop chassis open, critical restart key, USB, audio interface are in the chassis front panel, user-friendly user's use. 　　Next, let's take a look at the daily usage es

The Ipmitool–i Open Sensor List command obtains various monitoring values in the sensor and monitoring thresholds for this value, including (CPU temperature, voltage, fan speed, power modulation module temperature, supply voltage, etc.)Ipmitool–i Open sensor get "cpu0temp" can get the ID cpu0temp monitoring value, Cpu0temp is the sensor ID, the server is different, the ID representation is also different.Ipmitool–i Open Sensor Thresh sets the various limit values for the monitoring entry with ID

automatically start when connected. Finally, we will start the system. Don't be surprised. Although we don't have a button to switch on, we can use the 2pin switch on the short-circuit motherboard to boot normally. The 2pin switch on the motherboard is usually located in the lower left corner (Figure). You can find the exact position in the manual or printed on the PCB. If you touch the conductive material such as the key, The ATX power supply will start immediately. If everything goes well, y

Thanks to the convenient assembly and scalability of PCs, the popularity of computers has been accelerated to a certain extent, and manufacturers of computer accessories have naturally made great contributions to this. However, because the computers we use (especially compatible computers) are a combination of products produced by different manufacturers, there will inevitably be "friction" between them ". This is what we usually call incompatibility. The so-called "compatibility" word also come

four-core power plug at the power output end is inserted at the clip seat. 　　4-core power connection: In addition to connecting common ide devices, the 4-core power plug can also provide power to the fan or video card of the purchased chassis. Switching is often required for connection, you only need to insert the public header at the output end into the master header at the connection end. 　　CPU fan connection: After a radiator is installed for the

Professional Skills ---------------------------- Three aspects: 1. hardware knowledge 2. System Maintenance 3. Foreign Language 1. hardware knowledge I. hardware maintenance 1. Basic judgment on hardware damage First, listen carefully to hardware such as the hard disk and power supply fan for abnormal sound

that the biggest difficulty in R D of router cluster products lies in the Information Synchronization and collaboration between multiple devices to achieve data exchange plane and system control plane. "In addition to integrating the functions of all single devices, the Cluster also needs to handle the changes brought about by multiple chassis, which is much more complicated than the design of a single device ." Jin Xin said. It is worth noting that

No fault is displayed at startup. (No alarm sound) Step 2: First, check whether the external wiring of the computer is connected, and re-insert the connections to check whether the fault is rectified. Step 2: If the fault persists, open the trunk box to check whether there is any excess metal in the chassis, or short circuit caused by deformation of the motherboard. Then, smell whether the chassis is bu

At present, there are a lot of users, when the mic is connected before the connection can not be successful. Here is a detailed description of the wiring method of the front microphone for your reference. 　　I. Intel specification for front-facing audio interfacesIntel has regulated the front audio interface sockets, cable, and pin names for motherboards and chassis in the Front Panel I/O connectivitydesign Guide.

Many friends will install an efficient radiator in the mainframe to ensure a long period of stable operation, high-end gamers and game enthusiasts pay particular attention to heat. As an important part of the chassis operating environment, the heatsink does require the player's heart. However, not all users are familiar with the way the hardware is used, some DIY novice to the radiator selection and use of a certain misunderstanding, but also vulnera

occurs mainly in the low frequency, disconnecting the circuit board or chassis from the earth will have a certain effect. According to the mechanism of common mode current generation, the effective method to reduce this common mode current is to reduce the impedance of the differential mode circuit, so that most of the signal current is returned from the signal ground. Generally, the closer the signal line is to the return line, the smaller the imped

The remote server monitoring system is something that many network administrators need to learn and master. Today we take the remote monitoring system of DELL servers as an example to describe the remote server monitoring system in detail. The Dell PowerEdge M1000e modular blade server chassis and four Dell PowerEdge M600 blade servers are the most important products in the history of the evaluation room, and a bunch of boxes, big and small, are scary

IPMI request/resoponse message. The message has an IPMI session header and RMCP header. IPMI supports operating system shutdown (pre-OS and OS-absent) Using Remote Management Control Protocol (RMCP) Version 1. RMCP sends data to UDP port 623. Like LAN interfaces, lanplus uses the UDP protocol of Ethernet LAN to communicate with BMC, but lanplus uses RMCP + protocol (described in ipmiv20) to communicate with Iot platform, RMCP + allows the use of the modified authentication method and data inte
