Troubleshooting Checklist
Routine maintenance to this RossGear product is not required. In the event of problems with your
CMA-8011A-7, the following basic troubleshooting checklist may help identify the source of the
problem. If the module still does not appear to be working properly after checking all possible causes,
please contact your Ross Video products distributor, or the Ross Video Technical Support department
at the numbers listed under the “Contact Us” section at the end of this manual.
1. Visual Review – Performing a quick visual check may reveal many problems, such
as connectors not properly seated or loose cables. Check the module, the frame, and
any associated peripheral equipment for signs of trouble.
2. Power Check – Check the power indicator LED on the distribution frame front
panel for the presence of power. If the power LED is not illuminated, verify that the
power cable is connected to a power source and that power is available at the power
main. Confirm that the power supplies are fully seated in their slots. If the power
LED is still not illuminated, replace the power supply with one that is verified to
work.
3. Reseat the Card in the Frame – Eject the card and reinsert it in the frame.
4. Check Control Settings – Refer to the Installation and Operation sections of the
manual and verify all user-components.
5. Input Signal Status – Verify that source equipment is operating correctly and that a
valid signal is being supplied.
6. Output Signal Path – Verify that destination equipment is operating correctly and
receiving a valid signal.
7. Module Exchange – Exchanging a suspect module with a module that is known to
be working correctly is an efficient method for localizing problems to individual
modules.
