LED state
Definition
Flashing (1 Hz) The LED turns on and off with a frequency of 1 Hz: “On” for 500 ms,
followed by “Off” for 500 ms.
Flashing fast
green/red/
green
The MS LED or NS LED turns on green "On" for 250 ms, then red "On" for
250 ms, then green "On" (until the test is completed).
Flashing
sequence red/
green/off
The MS LED and NS LED each turn red "On" for 500 ms, then green "On"
for 500 ms, then "Off" for 500 ms. This flashing sequence is repeated at

Flickering
(load
dependent)
The LED 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 LED turns on and off in irregular intervals to indicate
low Ethernet activity
