5.10. Status LED Function
During the normal detection sequence, the STATUS LED flashes at approximately 3 times per second as the
detection process continues. After successful power up, the LED glows continuously. If there is an error condition
(i.e., class level is beyond programmed value, or a fault or over current condition has been detected), the LED
flashes rapidly at 10 times per second). This occurs for two seconds for normal error delay and, in the case of the
"restart after a RESET condition," the LED will flash rapidly, and the detection process will automatically start again
after 2.2 s and power will not be provided until an open circuit condition is detected. Once the Si3460-EVB detects
an open circuit condition, the LED blinks at 3 times per second.
If the Powered Device (PD) is disconnected so that a disconnect event occurs, the LED will start flashing at 3 times
per second once the detect process resumes.
