High Power PoE Operation
This Industrial Web-Smart PoE & High Power PoE Ethernet switch is compliant with the 802.3af and
802.3at High Power standard, providing 30W of pure power to power demanding devices such as
pan-tilt-zoom (PTZ) network cameras, wireless access bridge/routers and large-screen network
video phones et cetera.
This 802.3af High Power switch s PoE operation with 802.3at based PD is highly versatile and
adaptable. Normally, when an 802.3at PD is connected to an 802.3af High Power compliant switch,
the switch will detect that the PD s power requirement is based on class 4 classification outlined in
the IEEE802.3at standard, and only attempt to provide 15.4W of power, which is insufficient to
power a 30W 802.3at PD. This is due to the reason that the 30W of power in 802.3af High Power is
classified as class 0. However, this 802.3af High Power switch can support 30W 802.3at PD by
setting the switch explicitly to provide a fixed rate of 30W power to 30W 802.3at PD.
Power limit by classification: Uncheck Power limit by classification to disable Port 1 ~ Port 4 to
provide power to 30W 802.3at PD according to classification of maximum power range used by PD.
Fixed power limit(W): C
Fixed power limit(W) and type a new fixed power limit 30W
for Port 1 ~ Port 4 to provide power to 30W 802.3at PD.
