Normal:
There is no PD is detected on corresponding port. The end point device may not support the
PD function or the PD function is turned off on this device.
Power management cause fail:
The power feeding is temporary shut down because of PD suddenly
require more power which over the maximum power limitation defined on corresponding port. Please
disconnect the PD and check if there is damage or short happen on the PD.
Over current:
The power feeding is temporary shut down because PD requires more than 350mA power.
Please disconnect the PD and check if there is damage or short happen on the PD.
Short circuit:
The power feeding is temporary shut down because the circuit of the ethernet cable might
short somewhere between switch and PD, you may use the cable diagnostic function to check the status
of the cable and define the distance of short.
Power ON:
