, and then use ping to check, if the general rule of failure to solve. It is also possible that the line away from the network Management center of the end of the plug loose, you need to check the terminal equipment connection status. If the socket is not a problem, you can use the network cable test equipment for path testing, found that the problem should be replaced by a network cable. Another common physical failure is the network plug mistakenly connected. This situation is often caused by

the contact shape of "first touch"/"then disconnected" can provide an independent Arc area and is completely isolated from the coupling interface area on the connector and outlet contact, Optimal reliability for simultaneous power and Data Transmission 5. There is a modular socket Core Component suitable for all requirements of copper cabling connections, such as integrated flat/diagonal ports, or Keystone and full color jumpers) Electrical Enhancement Eliminate the variability of RJ-45 modular

How to connect two computers by Direct Cable Connection 1.making Crystal HeadsWhen connecting the two computers via a network cable, the Crystal Head connection of the network cable is: one end presses the t568a line sequence, the other end presses the t568b line sequence to connect. After the network cable is finished, the computer is connected by the crystal head of the network cable, so that the physical

connection between the Hub (switch) and the workstation computer, that is, the scope of the application of "Direct Connection. Iii. Information module jumper rules The patch cord rules of twisted pair cables are introduced above, because in enterprise networks, the cable head is not directly inserted into the hub or switch, instead, the network cable from the hub or switch is first connected to the information module and buried on the wall. This involves the core line arrangement sequence of th

1. you can directly use the ICS shared by the operating system-one machine as the host, which is used to dial up and install dual NICs (so you do not need to purchase additional hubs or switches, you only need to add one more NIC-two computers have three NICs, and make sure that machine 2 needs to access the Internet, machine 1 is the master server ).ICS (Internet Connection Sharing) is a shared Internet service built into Microsoft Windows 2000/XP. When using this service, you only need to chec

The slow speed of several reasons: First, the network itself problem The destination Web site you want to connect to is on a server with insufficient bandwidth or too much load. The processing method is very simple, please change the time period to go up again or change a target website. Second, network cable problems caused by slow speed We know that twisted-pair wires are tightly twisted and together by four pairs of lines to reduce crosstalk and background noise. At the same time, only 1,

Computer network failure is unavoidable. The network fault diagnosis is the important work of network management after the campus network is built and run. Generally when the network occurs information is not available, can not browse the Web, and other connectivity failures, the phenomenon is relatively clear, easy to observe and locate the fault point, such a fault is not difficult to solve. But the most troubling thing is that the internet is a pass, but the network speed slows down. When fac

twisted-pair wiring. Many users in the wiring often appear one is to use one by one of the corresponding error connection method, when the connection distance is short, the system does not appear connection fault. However, when the connection distance is long, the network is busy or high-speed running, it is easy ..., its core is to let 3 and 62 pins for the same pair (according to T568A or T568B standard

"pass" and "impassability" line order problem. Many users in the wiring often appear one is to use one by one of the corresponding error connection method, when the connection distance is short, the system does not appear connection fault. However, when the connection distance is long, the network is busy or high-speed running, it is easy ..., its core is to let 3 and 62 pins for the same pair (according to T568A or

For network management, LAN speed is one of the most troublesome things. If the network is not pass, but can quickly find the reason, but if the network is a pass, but the speed of slow, this is the most headache. When faced with this kind of "soft" fault for the first time, some people will be helpless. This article introduces the causes of such "soft" failures and their elimination methods, so as to improve the ability of dealing with practical problems. One, network cable problems caused by

pairs of wires in strict terms to reduce crosstalk and background noise effects. At the same time, only 1, 2 and 3, 64 lines of twisted pair are used in the T568A standard and t568b Standard, of which 1, 2 are used for sending, 3, 6 for reception, and 1, 2 must come from a pair, 3, 6 must come from a winding pair. Only in this way can we minimize crosstalk and ensure data transmission. Not according to the

1, the server problem First of all, network service providers, such as the user's telecommunications, if the network of service operators is not stable, then how to set all is useless. So make sure the server has to be stable first. Of course, the website's server also includes it, some websites its server is abroad its own speed is very slow, all even if our own network speed quickly open this page is very slow. 2, network cable failure Then it is when we are connected to the Internet networ

The network cable is already inseparable from our life. Because we often use the network cable, we need the network cable to access the Internet. Therefore, we need to learn how to make the network cable so that we can better control our life in Russia, Okay. Let's just talk about the network connection methods. This is the network connection method of two national standards. Generally, we use the second It may be difficult to remember this. I will teach you a simple method. Let's talk abo

problem with the computer, but the problem is that only the package can not receive the package, it is useless to change the number of computers. Is the connection line between the main switch and the switch on the floor damaged when cabling? Chen Yutong: it seems that there may be a line problem, provided that the switch port and the computer port can normally send and receive packets on other lines. It is recommended that you use the Integrated Wiring System tester to test the channel transmi

test the channel transmission performance of the line, including the jumpers at both ends, connectors at both ends (distribution frames and information sockets) and cables, select 5E or 6 according to the actual situation. At the same time, make sure that the Jumper used meets the line sequence standard of T568A/B. Q: What are the special requirements for Fiber Channel cabling in the data center machine room?
