2.5 PoE Port LED Indicators
The LED light indicators on the PoE copper port can help the user know if and when an event immediately
occurs or is happening. When the event is happening, you can verify the event from the Dual-color LED
status. If the port has recovered from an event, you can verify the event from the blinking frequency of the
PoE LED (5 seconds as a cycle).
Power Budget Exceeded Event
When the total PoE budget is overloaded (>100%), the PoE port of the lowest priority PoE port will be shut
down. The PoE LED of the port will act cyclically as below until the port is recovered from the event:
Figure 2.4 - PoE Budget Overloaded LED Sequence
After the PoE port is recovered from the PoE budget overload event, the PoE LED of the port will act
cyclically as below until the event indicator is clear manually:

PoE Port Over Current Event (PoE Port Overload Event)
When the current limit of the specific PoE port is exceeded, the PoE power will be shut down. The PoE
LED of the port will act cyclically as below until the port is recovered from the event:
