Internet access to crystals is not difficult, but it is easy to say, the most important of which is the question of the sequence of access。
There are two practice criteria for web-line crystals, tia/eia568b and tia/eia568a, respectively。
568a standard: green white, green, orange white, blue, blue white, orange, brown white, brown
568b standards: orange, orange, green, white, blue, white, green, brown, white, brown
Web lines are generally connected in two ways: straight lines and cross-lines。
1. The direct line approach is two-fold, from the left to the right, 568b, or both, 568a, but the two-head 568b is the norm, which is usually used:
When the liner is removed, both entangled lines are removed, sequenced, and eight lines are cut flat。
Crystal copper chips and dimples up, left to right, lined up, crystal inserted. Head
Put the crystal head in the pressurer's head tank and prepare the final pressure. Put your hands on the handle of the plier and press hard
The cross-line approach is two-pronged, 568b on the left to the right, 568a on the one end, and the other steps are the same as the straight line approach。
In fact, 568a and 568b's sequencing criteria are the movement of orange and orange white, green and green lines。
3. Applications of direct and cross-lines are normally:
Use of direct lines:
1. Connecting switches or hubs to routers
Computers (including servers and workstations) connected to switches or hubs。
Use of crosslines:
1. Upl between switches and switchesInks mouth connection; 2. Hub connection with switch; 3. Hub connection with hub
4. Two pcs directly connected (net-to-net cards)
5. Connection of router interface to other router interfaces
6. The adslmodem interface for the ethernet interface is connected to the network interface for the pc machine。
What we use in our daily lives is a straight line。
