Troubleshooting Checklist 

Routine maintenance to this RossGear product is not required. In the event of problems with your 
RSA-7806, 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 section 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.
