AC Power - The LED blinks green at approximately 1.5 times per second to indicate that the Power
Injector is powered ON and ready for connection.
AP Power - The LED lights solid green to indicate that a valid IEEE 802.3af load (AP) is detected and
powered ON.
Invalid load connected or Fault: The LED rapidly blinks green at 10 times per second to an invalid load
connected or a Fault. In these conditions the AP has not been powered on. This occurs for 2 seconds for
normal error delay, and the detection process will automatically start again after 2.2 seconds unless there
is a "restart after disconnect condition" set during the initial con guration.
