LED State
Definition
Triple Flash
The indicator shows a sequence of three short flashes (each 200 ms), separated by a short off
phase (200 ms). The sequence is finished by a long off phase (1,000 ms).
Blinking (2.5 Hz)
The indicator turns on and off with a frequency of 2.5 Hz:
“on” for 200 ms, followed by “off” for 200 ms.
Flickering (10 Hz)
The indicator turns on and off with a frequency of 10 Hz:
“on” for 50 ms, followed by “off” for 50 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.
