10/100/1000BASE-T autosensing Ethernet port LED
shows the description of 10/100/1000BASE-T autosensing Ethernet port LEDs on
switches that do not support the mode button.

LED status
Description
Steady green
A link is present on the port.
Flashing green
The port is sending or receiving data.
Off
No link is present on the port.
For switches that support the mode button, the 10/100/1000BASE-T autosensing Ethernet port
LEDs work in conjunction with the mode LED to indicate the operating state of the ports from
different aspects, as shown in

status
Description
Steady green
(Link/Active mode)
Steady green
A link is present on the port.
Flashing green
The port is sending or receiving data.
Off
No link is present on the port.
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
the port.
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 other port LEDs are off, the IRF member ID of the
switch is 4.
