Intersection line: One is t-586a standard on the other end is the standard of t-568b can be directly connected to two computers (network card to the network card)
Ordinary network cable (straight line) at both ends are generally t-568b standard
So: Need a specially made cable, or have a spare line to change it can also be changed only a head. When making the crystal head, the other end of the 1th and 3rd to swap, 2nd and 6th root swap
About intersection lines and straight lines:
the line order of 568A is from left to right: Green white, green, orange white, blue, blue white, orange, brown white, brown.
The line order of 568B is from left to right: orange white, orange, green white, blue, blue white, green, brown white, brown.
The crossover line refers to the 568A standard at one end and the 568B standard twisted pair at the other end.
Straight line refers to: Both ends are 568A or both are 568B standard twisted pair.
The order of the intersecting lines:
(from left to right): green white, green, orange white, blue, blue, white, orange, brown white, brown.
The other end (from left to right): orange white, orange, green white, blue, blue white, green, brown white, brown.
Order of Straight Lines:
At both ends (from left to right): green, white, green, orange, blue, blue, orange, brown, brown, white
Or at both ends: Orange white, orange, green white, blue, blue white, green, brown white, brown.
When using a pass-through line:
1. Connect the switch or hub to the router;
2. Computers (including servers and workstations) are connected to the switch or hub.
When using cross-line conditions:
1. Connection between switch and switch via uplinks port;
2. Hub connected to the switch;
3. Connection between hub and hub;
4. Two PCs are connected directly (network card to network card);
5. The connection between router interface and other router interface;
6. The ADSL modem of the Ethernet interface is connected to the PC's NIC interface.
The simple point is thatthe same layer of equipment connected with a crossover line, a different layer of equipment connected by direct connection.
Alternatively, if the two ports are of the same type, a crossover line is used, and if the two port types are different, a direct connection is used.
As for the two computers connected directly to thesettings:
With the correct network cable connection, the automatic acquisition of IP can also, configure the Home Network Wizard
Or the IP of the two machines is set to: 192.168.0.1 and 192.168.0.2 (similar) can be transmitted data.
★ If it is a dual-machine direct, you must use a crossover network cable (in fact, 12,364 lines cross), in fact, the telecommunications ADSL provided by the network cable is the cable, the two sides of the arrangement of the way is:
1 2 3 4 5 6 7 8
3 6 1 4 5 2 7 8
If you are using a simple network cable measuring instrument, its light jump order should be: 12→45→78→36→12, the following more detailed again:
One end: white orange/orange/White green/Blue/Bai Lan/Green/white brown/Brown (12345678) 1 2 3 4 5 6 7 8
End: White green/green/white orange/Blue/Bai Lan/orange/white brown/Brown (36145278) 3 6 1 4 5 2 7 8
Now the network card (after 04) generally have to automatically determine whether the network connection requires parallel lines, or cross-line, and then automatically change the mode to accommodate the connection.
