Switch PoE 8 ports POE-FSH804AT Airlive

It's a switch 8 ports 10 / 100Mbps with PoE function 802.3at / af standard feature on 4 ethernet ports.
It can automatically detect the presence of IEEE 802.3af and 802.3at devices providing power via the Ethernet port.
The switch provides up to 30W per PoE port and can be used for the direct supply of Access Points, IP cameras, IP phones, etc..
The switch has a protection mechanism that alerts you when there is a power required overload.
If the total power consumption is greater than / equal to 60W, the doors will be locked automatically on the basis of the priority of the switch * internal system.

* Priority: The priority of the port 1 is greater than the port 2 (port1> port2> porta3> porta4).
Take for instance the door 1 is connected to a device that is using 30W (maximum power per port), and that the gates 2 and 4 are connected to two devices that use 15W each; the system will use a total of 60W. If a further device is connected to port 3 that consumes 10W, the switch will stop the power supply of the door 4 (the one with the lowest priority) continuing to supply power to all ports except to it.
