At present, with the pace of network product updates accelerating, a considerable number of enterprises and institutions have eliminated and redundant network devices. It would be a pity to discard or discard them. At this time, it is a good idea for network administrators to use them to build a small online lab platform. In addition, there are many training courses, and we also need to build an online lab platform for students of the Learning Network to practice. The following steps allow you t

requires "authentication", the final performance test will not result in wiring errors or open-circuit short circuits. Because the installer can solve such problems at any time through F620. This can save a lot of time for fault diagnosis and locating. Verify cable link Routing Connect to fluke's "Cable identification" option in the complete LAN link. Installation engineers can use F620 to verify the link's routing and cable identification. In addition, the installer can detect two other wiring

They are composed of twisted pair wires and

standards. They are plug-and-play and support full duplex mode. 3. POF-RJ45 Optical Transceiver POF-RJ45 optical transceiver is an Ethernet optical interface to RJ45 converter. It provides a POF fiber port and a twisted pair port with an RJ45 connection interface. It converts electrical signals from an Ethernet networ

In the construction of a wireless network, wireless route connection settings are a key point. If the settings are incorrect, frequent faults may occur, and security is not guaranteed. Let's take a look at the wireless route connection settings. The specific operation steps have been summarized for everyone. Wireless route connection setup Part 1: physical connection 1. connection between a wireless router and a superior device: 1. When the upper-level device is an ADSL digital cat, the output p

Trunk area: consists of five types of UTP/STP or optical cables connected from the network center to the HUB on each floor.Horizontal zone: consists of five types of UTP/STP connections between cabinets on each floor and each information outlet on this layer.Device zone: it consists of floor hubs, cabinets, distribution frames, and UPS power supplies.The cabling s

It converts electrical signals from an Ethernet network to optical signals transmitted on a POF plastic optical fiber, a

of ADSL Internet sharing cannot be achieved. Under normal circumstances, the purchased ADSL Broadband modem will give a random network cable, which is usually a cross-network cable, that is, one end of the network cable is produced according to the 568B wiring standard, the other end of the network cable is produced according to the 568A wiring standard. However, when observing whether the network cable belongs to a crossover network cable, you only need to place the

used, then there is only one RJ45 connection connected to the link, if the use of an adapter-free cabling System test scenario, there will be more than one additional RJ45 connection in the link. As we all know, the RJ45 connection for the cable structure is to play a destructive role, RJ45 Crystal Head performance is

Because the cat5e twisted pair wires on site may be more than 100 meters long, which is a very large interference source,The

The process is as follows:　　 Figure 1: Data Flow Direction of Traffic parameters Debugging process　　I.

computer that is connected to the Internet) should be placed in the direction of the Internet phone line, because the shorter the telephone line the better. 　　Two. LAN Cabling The first step is "Put the line", determine the network hub and the distance between each computer, intercept the corresponding length of the cable, and then the network cable pipe (PVC pipe). You can also walk directly along the wall without having to wear a tube. It should be noted that the length of the twisted pair

failures are connected to the physical cabling, the production of network cable and the method of Plug and pull are closely related to the performance of network transmission. For example, if the physical connection cable we use is not manufactured according to the T568A Standard and the T568B standard, then the Internet signal is transmitted on the cable , it is easy to be disturbed by the outside world, when using this cable to access the Internet,

types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e category and marked with different colors. Twisted Pair wires have two Connection Methods: EIA/TIA 568B standard and EIA/TIA 568A standard. The specifi

The TCP/IP model consists of the following layers and main functions: the application layer directly provides services for your application process. The transport layer is responsible for providing services for communication between two host processes. The Internet layer is responsible for providing basic data packet transmission functions so that each packet can reach the target host. The Network Interface Layer receives and transmits IP data packets, receives physical frames from the network,

Flexibility In a data center, the device can be configured with both the optical network card and the copper network card, and the number of two ports for different devices and specific applications does not have a definite value, this requires that the cabling product be flexibly configured according to specific requirements. Hybrid-Patch adopts a modular structure and can be divided into different modules, each module can be installed with a number of modules as n
