Precautions for installation of network devices on the home network (1)

The penetration rate of various network devices in the home is getting higher and higher. But what problems should I pay attention to when installing home network devices?

1. correct installation and connection

According to the feedback from various aspects, some seemingly basic problems have plagued many ordinary home network users. Broadband MODEM is an essential device for many families. Correct Connection to it is a basic skill for installation. During the connection, the telephone LINE must be connected to the LINE port of the voice splitter. The telephone LINE is derived from the PHONE port of the splitter, And the ADSL telephone interface is connected to the MODEM port of the splitter.

Connect the crystal head at one end of the network cable to the LANRJ45 interface of the ADSL Router, and connect the other end to the computer network card or switch. Note that the network cable must be connected to the main line (that is, the direct line ).

After the power is turned on, ADSL will Initialize. After the initialization is complete, the LAN light should be on. If the light is not on, it may be caused by a problem with the network cable or network card. Please try again. The ADSL lamp should also be bright. If the flash shows that the synchronization with the ISP Server has not been completed, please wait. If the synchronization has not been completed for a long time, check whether the ADSL telephone line is connected.

 

All mainstream network devices support automatic port flip

The key point is to pay attention to the line sequence problem when using ADSL, network card, switch or Broadband Router to connect to each other. Although the current mainstream network devices support automatic port flip Auto MDI/MDIX) or Auto Uplink automatic forward/backward), there will always be one or two MDI on the previous network devices) or MDIX cross) interface, while Auto automatic/adaptive) the emergence of the MDI/MDIX interface removes all this.

The direct benefit of this solution is that you do not need to consider the issue of direct connection and cross-line when selecting a network cable. However, if you do not need to worry too much about it, it does not mean that you do not need to worry about it at all. In a switch interface, the mix of too many express lines and crossover lines will bring more or less negative effects. In addition, some users do not perform straight-through twisted pair wires in line Order, resulting in many problems.

Therefore, when installing and using network devices, it is best for home users to strictly follow the twisted pair wires. Both ends of the crystal head of the straight-through cable follow the 568A or 568B standard. Each group of twisted pair wires is one-to-one, which is used to connect the UPLINK port of the switch to the common port of the switch or the common port of the switch to the computer Nic.

The end of the Cross-cable crystal head follows 568A, while the other end follows the 568B standard. The 1 and 2 of the crystal head correspond to the 3 and 6 of the B crystal head. The 3 and 6 of the crystal head correspond to the 1 and 2 of the B crystal head. This interface is used to connect a common port of a vswitch to a common port of a vswitch or to a nic.
