LED state
Definition
On
The indicator is constantly on.
Off
The indicator is constantly off.
Single flash
The indicator shows one short flash (200 ms) followed by a long “off“ phase (1,000 ms).
Double flash
The indicator shows a sequence of two 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).
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).
Quadruple Flash
The indicator shows a sequence of four 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.
Single Flickering
The indicator is switched on and off once: 'on' for 50 ms, followed by 'off' for 500 ms.
Double
Flickering
The indicator is switched on and off and on once: 'on' / 'off' / 'on' each for approximately 50 ms,
followed by 'off' for 500 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 dependant)
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.
