the switch is outputting 0 to 20% of the 
maximum PoE output power.  

 

10/100/1000 Base-T Ethernet port LED    

Each 10/100/1000Base-T auto-sensing Ethernet port has a status LED to show port operating status and 
activities. The port mode LED indicates the type of information (for example, port rate or duplex mode) 
that the port LEDs are showing. You can use the port LED mode switching button to change the type of 
port information that is displayed.
