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) 
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 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.
