DC input voltage
LED
Function
20W/30W
Flashing three
times means the DC input voltage is 48~51
V.
40W/60W
Flashing three times means the DC input voltage is 52~54
V.
60W+/90W+
Flashing three times means the DC input voltage is 55~56
V.
PoE mode
PoE Mode
Description
Standard
Fully conforms to the IEEE
802.3
af/at/bt standard.
Legacy
Legacy detection identifies PD devices that do not fully follow the IEEE
802.3
af/at/bt standard and their unique electrical signatures so that the PoE
injector can provide power to those PD devices. Legacy mode will
handshake to check if this connected device is a PoE device first. If
handshaking fails, forced output power is used.
