First, login switch First find a console line that connects the computer's serial port to the console port of the switch. (Note: console[console] One end of the line for the RJ45 Crystal Head, one end with the DB9 of the serial port, if you want to make this line, you can use a UTP cable will be used to connect the two ends, that is, the opposite ends of the line sequence, and then with a RJ45 to DB9 conne

. Build a small local area network at home, just apply for a broadband Internet connection, so that each room can use the computer at the same time Internet. In addition, with the trend of Home appliance network, Network Audio-visual center, network refrigerator, network microwave, network video monitoring will appear, these devices can find the nearest network interface access network. Wiring characteristics: The general LAN is a star topology structure, any node or connection cable failure, w

, to meet the needs of data communication, has a strong application value. 1 Ethernet-based laser wireless communication system The combination of Ethernet and laser wireless communication can give full play to the advantages of the two systems and improve the application range and reliability of the system greatly. Fig. 1 is a schematic diagram based on one end of the Ethernet laser wireless communication system, and the other end of the structure and the end of the symmetrical state. From

, according to the replacement of products, can be changed to 1, 2, 3, 4; A2 for the 5-L2/L3 switch, currently 5, according to the replacement of products, can be changed to 6, 7, 8, 9; A3A4 two digits are related to the number of ports in the product, which determines the product family based on the total number of ports: A3A4 is 08-indicates that the downlink port is 8, the uplink port is 0, 1, 2; A3A4 is 12-indicates that the downlink port is 12, the uplink port is 0, 1, 2; A5 is used to

Take the Samsung notebook from the "Samsung set up Center" for example, on the Network tab, in the Move Hotspot settings interface, open the switch that uses my device as an Internet access point (AP) to automatically generate an SSID (Wi-Fi hotspot name) and a corresponding password. This is to share the notebook network (via RJ45 connected wired network) to other mobile devices. Similarly, Lenovo notebook can be in the "Lenovo Center" Netwo

At present, the construction of intelligent community has gradually become a hot topic, and the construction of data network will become an important part of intelligent community construction. At the same time, the intelligent and networked residential district will bring new market opportunities to the developers of the community. For intelligent community Construction, 3Com according to the different operating environment and user requirements, the following solutions are proposed: Intellig

lit Observe the back side of the NIC RJ45 side has two lights, they are the connection status LED and signal transmission led, where the normal state of the connection status indicator is green and long bright, signal LED is red, normal should keep flashing. If the connection LED is found, that is, the green light is not lit, it means that the network card connected to the hub or switch connection has a router failure. This can be used to block the

of twisted pair The distance between the server and the switch from 5 meters to 60 meters, the result is not connected anyway, why? Ethernet generally uses two pairs of twisted-pair lines, arranged in 1, 2, 3, 6 position, if the use is not two pairs of lines, but the original pair using the line used separately, will form winding, resulting in a larger crosstalk ( NEXT), which affects network performance. The reason for this failure is that 3, 6 do not use the pairing line, in the case of lon

How about a ThinkPad w550s notebook? First, the appearance of details 1, small black classic design lighter and thinner workstation 2, the overall appearance of the ThinkPad w550s continued the classic design of small black products, the shell of the use of carbon fiber material, fuselage internal metal skeleton, the strength of the machine is still very considerable. Interface is more abundant than general pen electricity 3, the ThinkPad w550s interface configurati

) wirelessly, without affecting the capabilities of their wireless AP coverage Tp-link tl-wr541g+ 2 units Notebook Terminal: 2 units 1 Network Diagram 2 Network application diagram 3 Several modes of wireless router application 1.AP mode The model is simply to switch our wired network into a wireless network! And then connect to a variety of wireless terminals, such as laptops or desktops with wireless connections. Connect the phone with WiFi and so on.

Mercury MW300R Wireless router, now as long as 560 yuan, a very cheap wireless router, suitable for several users of the family! Users can use the network cable Connection number, it supports PPPoE, dynamic IP, static IP and other broadband access mode to meet the needs of different users. Can be used to build intranet sites, the built-in firewall can be IP, MAC, URL address, such as filtering, effective control of the network in the host's Internet access and Internet access time, and its occup

It is relatively easy to build a network, but to manage the network is a relatively cumbersome work. And don't say the various requests that the user gives you will keep you busy, only the network does not pass this fault is enough trouble to solve, because the cause of the network is too many, as long as we will be the fault of the Regulation class, or have the law to follow, now the title of computer small set to you detailed explanation. One, the connection led is not lit Observe the back s

is different access to the optical line, is the light signal. Optical signal conversion and interface protocol after the conversion of the router, he belongs to a wide area network access, that is, often said fiber access, as long as the presence of optical fiber in the place need to convert the light of the cat. Optical fiber transceiver is the conversion of photoelectric signal in LAN, but only signal conversion, there is no interface protocol conversion. Generally used in the park network l
