High Power
If enabled, the proprietary Buffalo high-power function, an
extension of the IEEE 802.3af standards, allows a maximum of 30 W
to be supplied. Class 0 to 3 devices receive 15.4 W of power; class 4
devices may use up to 30 W.
If disabled, standard 802.3af power supplies up to 15.4 W max.
at:
LLDP packets are sent at 30-second intervals from ports set to use
802.3at. If the PD supports LLDP, power is dynamically adjusted. If
the connected PD is class 0 to 3, 15.4 W of power is supplied. For
class 4, 30 W of power is supplied (LLDP devices only).
If the power supply capacity is exceeded, power is supplied with priority to the port with the smaller
number.
