•
Supports IEEE 802.3af PoE and IEEE 802.3at PoE+ compliance.
•
Supplies power to PD devices up to 15.4W per port (802.3af) or 30W+ per port
(802.3at) more sufficiently.
•
Power Budget: 370W, 740W with RPS.
•
Supports the Auto Discovery feature. It'll automatically recognize a connection to PD
devices and immediately provide power.
•
Supports the Auto Disable Port feature. If the port's electrical current is over 600mA,
this feature will activate and still keep the other ports active.
•
Supports the Active Circuit Protection feature. It'll automatically disable a port if
there is an electrical short and still keep the other ports active.
