Usually, if the system seems not to transport the signal as expected, the best
strategy for troubleshooting is to check signal integrity through the whole
signal chain starting from source side and moving forward to receiver end.

11.1. Use Cases
At first, check front panel LEDs and take the necessary steps according to their states. For more information
about status, LEDs refer to the
Front and Rear View - F-series Endpoint Devices
section for the endpoint
devices and to the
Front and Rear View - UBEX-MMU-X200
section for the MMU.
Symptom
Root cause
Action
Refer to
Video signal
No picture on the
video output
Device or devices are not
powered properly
Check the endpoints, the MMU, the
network switch, and the other devices if
they are properly powered; try to unplug
and reconnect them.
Cable connection
problem
Cables must fit very well, check all the
connectors (HDMI and optical/DAC
cables).
Optical cable became
contaminated
Use special fiber optical cable cleaning
equipment to clean it carefully.
Incorrect settings are
applied in the network
switch
Check the configuration settings of the
network switch. See more typical switch
related issues on the next page.
Singlemode-multimode
SFP / SFP+ module pairs
Check the installed SFP / SFP+ modules
and install multimode or singlemode
modules by pairs only.
SFP module is installed
instead of SFP+ module
Install SFP+ transceiver module to the
SFP+ port
Incompatible SFP+
modules are in the
endpoint and the
network switch
Check the compatibility of the installed
SFP+ modules: singlemode / multimode
pairs, parameters of the modules
Not the proper video
stream is the active one
Check the crosspoint state which video
stream switched to the current output.
LW3
Video stream is disabled Enable the source stream.
LW3
Output port is disabled
Enable the destination stream.
LW3
Display is not able to
receive the video format
Check the emulated EDID; select another
(e.g. emulate the EDID of the display on
the input port).
