PoE Specification
Supplies power to PD device up to 15.4W per port, meeting IEEE802.3af standards
and more sufficiently is able to provide power to PD devices
A
uto discovery feature, automatically recognize the connection of PD device and
immediately sends power to it
Auto disable port if the port current is over 350mA while other ports remain active
Active circuit protection, automatically disables the port if there is a short while othe
r
ports remain active
