different, it is very important to find out the role of each port. The vswitch mainly includes a console control port used to configure Internet access parameters, two RJ45 ports connected to the external network, and four RJ45 ports connected to the internal network, both the Intranet and Internet ports belong to the 10/100 Mbit/s adaptive port. After understanding the role of each port, we can now connec

, ST, and LC. Currently, the common electrical interfaces are RJ45, which are used to connect to twisted pair wires and interfaces connected to coaxial cables. However, these interfaces are rarely used. Fc nic: it is also called an optical fiber Nic. Its learning name is Fiber Channel HBA. The transmission protocol is an optical fiber channel protocol, which is generally connected to an optical fiber channel switch through an optical fiber cable. Inte

flexibility of the patch cord from the distribution frame or device to the cable manager. This allows the jumper to maintain excellent external crosstalk performance while maintaining the same bending radius and cabling flexibility as the non-reinforced jumper. 10G 6A UTP BladePatch is a unique RJ45 patch cord that is pluggable without pressing down an external lock. Patented push-pull internal lock structure. When the plug is inserted into the socke

A Network Transformer will be added in the middle when the Ethernet device is connected to RJ45 through the phy. What is the role of this transformer? Theoretically, transformer can be directly connected to RJ45 without being connected. However, the transmission distance is very limited, and when connected to different levels of Network Ports, it will also affect. In addition, the external interference to t

Introduction to the OSI Layer-7 Model OSI is an open reference model for System Interconnection. It is a well-defined protocol specification. The OSI model has a layer-7 structure, and each layer can have several child layers. Next I will briefly introduce these 7 layers and their functions. Layer 7 of OSI is 7 Application Layer telnet, HTTP, FTP, WWW, NFS, SMTP6 presentation layer encryption, asii5 session-layer RPC and SQL4 Transport Layer TCP, UDP, SPX3 network layer IP, IPX2. data link laye

It seems that the RJ45 outlet of this website is not very standard. I am a golden wave crystal head that is used in all kinds of places, you have to polish it to get stuck. (Do not wear a lens. If it is not waterpro

connections. Basic knowledge about wireless network AP ③ Wireless Router A wireless router must be a Wireless Broadband Router. A wireless router is a network device that can be connected to a LAN or a WAN and has both the broadband routing and Wireless AP functions. There are two types of wireless routers. One is an ordinary dual-port wireless router without an exchange module. One RJ45 port is a WAN port used to connect to broadband, and the other

' terminal devices. It must comply with the ISDN standard and can meet the high-speed data transmission standard. Iv. Copper Cabling System Design Scheme The copper cabling system consists of the workspace subsystem, horizontal cabling subsystem, vertical trunk subsystem, management subsystem, and inter-device subsystem. A. workspace Subsystem The workspace subsystem consists of information sockets, connection sockets, and connections of terminal devices installed in various office areas. Here w

generally a 10/100 Mbps adaptive RJ45 port, which can be connected to devices such as xDSL and Cable MODEM or Ethernet. Common wireless route parameter 2 LAN port A Local Area Network (LAN) is a relatively limited geographical Area, A network composed of a group of computers, servers, printers, and similar device connections. The various multi-host networks we currently use belong to this category. Each computer (or other network device) on the LAN h

This topic simply understands the content of the port;Brief introduction:"Port" is the translation of the English port, it can be considered as the export of communication between the equipment and the outside world.The ports can be divided into virtual ports and physical ports, where the virtual (protocol) port refers to the inside of the computer or the port within the switch router and is not visible.For example, 80 ports, 21 ports, 23 ports, and so on in the computer.The physical port, also

extension number.Special wiring rack out, and then received the company network wiring cabinet (TV saw the room glass door 2 meters high, 0.8 meters wide, 1 meters thick iron cabinets, inside a lot of shelves, you can put the wiring rack, can be installed on the network switch, can be installed on the rack server) in the wiring rack, The wiring racks are then linked by a computer cable to the network sockets on the underside of each desk.Previously, each person under the seat of the telephone l

1.1 Application ScenariosThe interaction object of communication platform includes two aspects: first, interacting with hardware products. Second, interacting with software products. Basically these two aspects, communication platform will generally be used in two scenarios:1) Communication platform application on PCMainly used in the automatic station of the industrial computer, through rs485/rs232, RJ45, 4-20ma and other ways to collect data informa

Category 5 is 100 mb/s, while that of Category 5 is as high as 155 mb/s, which can meet the needs of multimedia data transmission in the future, therefore, Category 5 or more than Category 5 twisted pair wires are recommended. Twisted Pair wires can also be divided into shielded twisted pair wires (stp) and unshielded twisted pair wires (utp ). Although the stp twisted pair has a low speed (only 4 mb/s), its anti-interference capability is higher than that of utp twisted pair, so the price is m

adaptive NICs, the speed of the network adapter depends on the bandwidth of the network device connecting the other end. If the other end is connected to a m network device, the network connection will be switched to a m physical connection rate. It is worth mentioning that at present, Most laptop built-in NICs Support automatic adaptation of RJ45 568a and 568b in Two-line sequence, which makes it very convenient to create and find Ethernet connecti

SuperIO Communication Mechanism1.1 application scenarios Communication Platform interaction objects include two aspects: first, interaction with hardware products. 2. Interaction with software products. Generally, communication platforms are used in two scenarios: 1) The communication platform is applied to PCs. It is mainly used in automatic station industrial computer to collect data of hardware devices through RS485/RS232,

Use Cisco router reverse telnet to do Terminal ServerIf we have more than one router to do the experiment, if it is according to the control line of a single configuration will be very troublesome, so we need to configure a Terminal server to log on to other machines here, the following practices:Install the eight claw cable with Cisco 2509, and note that only the cables are installed and no DB25-RJ45 converters need to be mounted. Plug the eight claw

, such as Cisco's routers, are in this way to manage the device, a small console line is equivalent to a PC monitor plus keyboard, which undoubtedly saved the router a lot of unnecessary accessories, In fact, part of Cisco's equipment is a PC, such as Cisco PIX515 Firewall, as long as you plug in a PCI card to the PCI slot, connect the monitor, press the PIX switch, you can see an BX motherboard, Pentium II 350MHZ processor, 128M memory computer startup information, and a normal computer to star
