LED state
Definition
On
The indicator is constantly on.
Off
The indicator is constantly off.
Blinking (5 Hz)
The indicator turns on and off with a frequency of 5 Hz:
“on” for 100 ms, followed by “off” for 100 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.
