There are many kinds of switches, in addition to the hundred megabytes, Gigabit and Wan Zhaozhi points, there are no power supply and power supply, in which the switch with power supply is called PoE switch.
The PoE switch is also a network switch, which has the data transmission function of all switches. In addition, it has the network power supply that other switches do not have. That is to say, using it can directly supply the network equipment connected to the network, so that they can operate normally. From above, PoE switches are generally suitable for access layer because they need to connect to network devices and access upconverge switches upwards. The power supply function of PoE switches is due to its internal PoE power supply chip, which can control the power supply and power supply.
PoE switches can help simplify construction without additional power wiring, which gives it a simple and convenient advantage. Its advantages can be perfectly applied to wireless coverage, network monitoring, building intercom and other fields. Wireless AP in wireless coverage needs power to operate, monitoring cameras in network monitoring need power to work, and PoE switches can solve their power supply problems, without the construction team's additional dug and wiring, making the project more simple and saving time.
At present, the application of PoE switches has been fully carried out in the field of wireless coverage and monitoring. There are nearly 70 kinds of CCIT PoE switches, and suitable models can be found for any scale of network engineering, so as to save engineering cost greatly.
