LED state
Definition
Flashing (1 Hz)
The indicator turns on and off with a frequency of 1 Hz:
“on” for 500 ms, followed by “off” for 500 ms.
Flickering (load
dependent)
The indicator turns on and off with a frequency of approximately 10 Hz to indicate high Ethernet
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
