PoE power circuit shortage.
Power over current: over the power current of PD’s classification.
PoE voltage of 44 ~ 57 VDC output range.
Off :
The LED will be off when there is no PoE powered device (PD) connected to the port.
Management Port Status LEDs
LINK/ACT
On :
The LED will light up green when the port is connected to an Ethernet network.
