10. Troubleshooting
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.
At first, check front panel LEDs and take the necessary steps according to their states. For
more information about status, LEDs refer to section 2.4 on page 12 and section 2.6 on
page 14 .
