What is a switch with PoE function
Hong Ruiguangxiang tell you what is a PoE function of the switch?
What is the switch
Switch (English: Switch, meaning "switch") is a kind of network device for electrical signal forwarding. The utility model can provide exclusive electric signal path for any two network nodes of an access switch. The most common switch is the Ethernet switch. Other common telephone voice switches, optical switches, etc..
The main functions of the switch include physical addressing, network topology, error checking, frame sequence, and traffic control. At present, some high-end switches also have some new features, such as support for VLAN (virtual LAN), support for link aggregation, and some even have the function of routing and firewall.
What is PoE
PoE (Power Over Ethernet) refers to the existing Cat.5 Ethernet cabling infrastructure does not make any changes in the situation, for some IP based terminal (such as IP telephone, wireless LAN access point AP network camera, etc.) for the transmission of data signals at the same time, this kind of equipment can provide DC power supply technology. PoE technology can ensure the existing structured cabling security while ensuring the normal operation of the existing network, to minimize costs.
What is a PoE switch
From the concept of PoE, you can know the PoE switch is able to provide remote power switch, power supply switches that support network, which can not only realize the function of data transmission can also supply power to the ordinary switch network terminal.
For example, you have a camera, is generally need to be plugged in, but if the environment take inconvenient, you need to use a PoE power supply, PoE power supply cable power supply is used, so there is no need to connect the power, you only need the camera is connected with a cable to the switch, data and power supply this cable transmission at the same time.
PoE switch type
PoE switch with fast and Gigabit Gigabit switches with fengrunda series 8 port PoE switch as an example, PS5081 fast PoE switch, PS1082T and 100 Gigabit PoE switches, PS1082G Gigabit PoE switches, providing 8 adaptive 10/100/1000M port, support the IEEE802.3af/at standard PoE ports, each port of the maximum output power of 30W. Million PoE switch PS7024XS provides 4 Gigabit adaptive port, so that video transmission is more fluent. In the selection, according to their own needs and network requirements to choose.
PoE switch application
Through the cable for wireless AP, network camera, network phone, handheld computers and other POE terminal equipment power supply, transmission distance up to 100m, simple installation, plug and play. Very suitable for wireless city, security monitoring and other industries.
