or 10/100/1000BASE-T
autosensing Ethernet port
LED status
Description
Off
No link is present on the port.
Flashing green (PoE
mode) (available only
for PoE switch
models)
Steady green
PoE power supply is normal.
Flashing green (1 Hz)
•
The maximum PoE power provided by the
port fails to meet the power requirement of
the PD.
•
PoE power supply overcurrent, overvoltage,
or short-circuit occurs.
•
The remaining power of the switch fails to
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 10/100/1000BASE-T autosensing Ethernet
port LEDs on the switch work in conjunction to
indicate the IRF member ID of the switch. For
example, if the LED for port 5 is steady green and
the other port LEDs are off, the IRF member ID of
the switch is 5.
