[. . . ] [. . . ] It will automatically detect the presence of an IEEE 802. 3af compliant powered device (PD) and provide power through Ethernet port. The switch provides up to 15. 4W per PoE port and can be used to power PoE AP, PoE IP phone, PoE IP Cam and other PoE devices. POE-FSH804 has the protection mechanism to mention users when power consumption is overloaded. If all PDs power consumption is 55W, the LED of "PoE Max. " will be red, and ports will be stopped receiving power based on priority* by system, then power of lowest-priority port will be cut by system. PoE-IPCam Internet POE-FSH804 PoE AP Data Power 5F, No. 96, Min-ChuanRd, Hsin-tien City, Taipei, Taiwan * Priority: Priority of port 1 is higher than port 2 (port 1> port 2> port 3 > port 4). For example, Port 1, 2 and 4 are using 15. 4w (maximum power per port is 15. 4W), the system power is 46. 2w in total (PoE max LED is red ). [. . . ] [. . . ]
