The 16 LEDs on the front of the 3405FC signify SFP module presence and signal status (1 through 16).
LED
Description
No LED
An unlit LED indicates that there is no SFP plugged into the associated port number.
Red LED
Red
LEDs indicate the presence of an error with the particular SFP inserted in the
corresponding port number, or it indicates a loss of signal (fiber or coax). A Red LED
indicates that the SFP is Present, but there are errors on the input signal and an input has
been unplugged from the SFP.
Green LED
Green
LEDs indicate the presence of a working SFP module corresponding to the SFP
port number. A Green LED indicates that the SFP is Present, there is a valid signal input,
and both inputs are plugged into the SFP.
Note:
Both fiber inputs (for receiver) or both coax inputs (for transmitter) will need to be
connected to the SFP in order for the LED to go Green.
