Ethernet port LED
status
Description
Flashing green
(PoE mode,
available only for
PoE switches)
Steady green
PoE power supply is normal.
Flashing green (1 Hz)
•
The maximum PoE power provided by the port does
not meet the power requirement of the PD.
•
PoE power supply overcurrent, overvoltage, or
short-circuit has occurred.
•
The remaining power of the switch does not meet the
power supply requirement of the port.
Off
The port is not connected to a PD or PoE is not enabled on

Flashing yellow
(IRF mode)
Steady green
The autosensing Ethernet port LEDs on the switch work in
conjunction to indicate the IRF member ID of the switch.
For example, if the LEDs for ports 1 to 4 are steady green
and the others are off, the IRF member ID of the switch is
4.
SFP port LED
The SFP port LEDs work in conjunction and the mode LED to indicate the operating status of SFP
ports.
