LED state Definition
Flashing The indicator turns on and off for 3 seconds with a frequency of 1 Hz:
(1 Hz, 3 s) "on" for 500 ms, followed by "off" for 500 ms.
Flashing The indicator turns on and off with a frequency of 2 Hz:
(2 Hz) "on" for 250 ms, followed by "off" for 250 ms.
Flickering (load The indicator turns on and off with a frequency of approximately 10 Hz to indicate high Ethernet
dependent) activity: "on" for approximately 50 ms, followed by "off" for 50 ms. The indicator turns on and off in
irregular intervals to indicate low Ethernet activity.
