Four matching methods of switch and distribution frame port

In the formation of local area network, in accordance with the general wiring of generic specifications, the construction should be used with "rice standard" network cable or on both sides of the crystal head set dedicated "special-shaped number", and in the cabinet to do with "rice mark" or "Number tube" corresponding to the computer identification record

Many units have a small number of original computers, later, gradually added some computers, composed of a certain size of the local area network, and the original network did not connect the computer cable to do the logo, or only 1234, ABCD such a paper label, easy to appear similar, a long time some logo will be ambiguous, This has brought inconvenience to the network maintenance work later. In the process of standardizing the local area network, it is a tedious task to pair the network cable connecting the switch with the computer, here are four common methods of pairing:

1. Using Network cable Wire detector: This is also the common method of people, unplug all the cables from the switch (or hub), connect the transmitter end of the cable to the network cable at one end of the computer, and then test the switch-side network cable with the receiving end, find the end of the signal-connected indicator, set the number tube, and insert the switch in the corresponding position, And make a record, complete a set of network cable matching work, and then the next set of network cable matching work. This approach is appropriate for a small number of computers in a local area network.

2. Turn on the computer: in the case of normal network connection, the power indicator of the computer card, the data led and the switch port position of the power led and the data lantern light up, according to this feature, we can turn on the computers, to observe the switch where the indicator lights up, The network cable of the corresponding port is the one that is connected to the computer that just opened. Some network cards, as long as the network card access to the LAN, power-on or not light is light, not suitable for this method.

3. Network cable "Hot plug": In the case of turning on the computer, unplug the network cable connected to the NIC, to observe which position on the switch lights off, so that the computer connected to determine the network cable. Truth and Method 2 is the same, however, hot plug on the computer has a certain degree of harm.

The above methods need to disconnect the LAN, by two people to complete, the computer and switch distance from the walkie-talkie, mobile phone to contact. If a person to do the work, the intensity of labor is very large. Some important LAN can not easily disconnect the network, then there is a relatively simple method? Of course it is!

4, large data copy method: We know that the switch and network card data indicators in the transmission will be fast flashing, according to this feature, we can copy data from the designated computer, by observing the switch fast flashing data indicators to determine the connected computer.

First borrow a computer next to the switch, make a shorter network cable insert the port specified by the switch, confirm that this computer can connect to the local area network (assuming this computer is named Test, access the switch port 1), and then check whether each computer in the LAN can access the local area network, you can open the "Network Neighborhood" See if you can find the computer for testing: test, and set a large data folder on your computer to be shared (for example, share C disk). In the network cable put on the "number tube", note the relevant data of this computer, such as the location of the computer, computer name, IP address, "Number of pipe" number.

The following can be done quickly pairing work. On the test computer, open My Network Places, double-click a computer, find its shared folder, copy large data files to the test computer, watch the switch's data LEDs, and the two-position LEDs should flash fast and continuously, one to connect the test computer to Port 1, Another port location is connected to the computer for data replication, put on the "number tube", note the port location, complete a set of network cable matching work.

Open Network Places on the test computer, locate the shared folder for another computer, and then copy the large data file to determine its port location on the switch. Complete the network cable matching work.

Finally, delete the files copied on the test computer and remove the shared folders that are set up on the computer in the local area network. Collate computer related data, computer and switch port correspondence and "number tube" marking records.

This method does not need to disconnect the LAN, detect the connection status of the computer, to the switch on the network cable matching a person can be completed, convenient and fast.
