An Ethernet switch with 4 ports 10/100 BASE-TX. Supporting POE (power supply via an Ethernet cable)
NetPing NP-SM4 is an Ethernet switch for 4 ports, designed in compact and convenient body of a wall computer socket. A peculiarity of this switch are its compact size and POE technology support for powering a switch itself and connected devices as well.
PoE (Power over Ethernet) is a technology of sending data and electric power through a standard twisted pair in an Ethernet network. For example, if your video camera supports PoE,it is enough to connect an Ethernet cable to plug it in, and there is no need to plug it to a 220 V network, as a camera will power through an Ethernet network. The technology is widely used in IP telephony, wireless networks access points, IP cameras, network hubs, IP weather stations. Using POE power supply can be critically important when connecting a separate power supply is undesirable or impossible. For example, in the installation place there is no external power outlet or an external power supply is unstable.
A switch NP-SM4 can get a power supply by a POE technology. I.e. just connecting NP-SM4 to an Ethernet network is sufficient and no other additional power supply for a switch is needed. Besides, there is a possibility to plug an external power supply adapter to NP-SM4, for those cases when a network does not support a POE standard.
A body of a device, looking like an add-on computer socket, is one of unique features of a device! It is mounted in the same way as an ordinary computer socket for connecting to a work place network and/or VoIp phones, and at the same time it contains a full Ethernet switch, which allows connecting new workplaces by just plugging a NP-SM4 into any available Ethernet slot!
If an external power supply adapter is connected to a NP-SM4, a NP-SM4 can be a POE injector in a network, i.e. add a power supply to an Ethernet cable. In such mode 3 ports of a NP-SM4 switch can POE power 3 external devices! For example, it is possible to POE power 3 external IP cameras or several VoIP phones.
NP-SM4 can provide a POE power supply to connected devices, including the same NP-SM4 switches, included after it. This peculiarity allows building a full randomly configured Ethernet network on a basis of NP-SM4, adding additional NP-SM4 devices for its branching in necessary places with no external power supply units connected.
