Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your
Network Controller Card, 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 Technical Support
department at the numbers listed under the “
Contact Us ” section.
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. 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.
MFC-8322-S Alarm Mute/Bootload Button
In the unlikely event of a complete card failure, you may be instructed by a Ross Technical
Support specialist to perform a complete software reload on the MFC-8322-S. The
Alarm
Mute / Bootload button enables emergency booting in case of flash corruption or, to recover
from a failed software upgrade.
The MFC-8322-S contain a primary software load and two backup loads. When the Alarm
Mute / Bootload button is pressed and held during power-up, the card will try the two backups,
in turn, instead of the primary load. If a valid backup is found, it is copied into the primary load.
If neither backup is valid, then all LEDs are lit to indicate a failure.
When running from a backup copy that differs from the primary load, the Frame Status indicator
in the Hardware tab of DashBoard displays “ Running a backup code ”. If this message displays,
Ross Video recommends performing a software upgrade to ensure that all copies remain valid.
MFC-OG3-N
This section provides additional troubleshooting information.
Using a Web Browser
Under the guidance of Ross Technical Support, the MFC-OG3-N may be recoverable via the web
interface as follows:
1. If the IP address of the card is known, use a web browser to try and connect to the frame
by typing the IP address into the browser window as
http:// xxx
where
xxx
represents
the frame IP address.
2. If this is successful, this provides access to diagnostic information for troubleshooting.
