Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your DFR-
8310 series frame, the following basic troubleshooting checklist may help identify the source of the
problem. If the frame still does not appear to be working properly after checking all possible causes,
please contact your openGear products distributor, or the Sierra 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 card, 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. Input Signal Status – Verify that source equipment is operating correctly and that a
valid signal is being supplied.
4. Output Signal Path – Verify that destination equipment is operating correctly and
receiving a valid signal.
5. Unit Exchange – Exchanging a suspect unit with a unit that is known to be working
correctly is an efficient method for localizing problems to individual units.
