Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your
9242, the following basic troubleshooting checklist may help identify the source of the problem. If the
card still does not appear to be working properly after checking all possible causes, please contact your
openGear products distributor, or the Cobalt Digital 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. Re-seat 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-adjustable component settings.
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. Card Exchange — Exchanging a suspect card with a card that is known to be working
correctly is an efficient method for localizing problems to individual cards.
