Installing the 9275-4C or 9275-8C
This section outlines how to install a Rear Module in a 8300 series frame. The same procedure applies
regardless of the frame or card type. However, the specific Rear Module you need to install depends on
your application and the openGear frame you are using.
Rear Modules for the 9275-4C
When installing the 9275-4C:
20-slot frame — The RM20-9275-4C-B Full Rear Module (R2C-8259) is required.
Rear Modules for the 9275-8C
When installing the 9275-8C:
20-slot frame — The RM20-9275-8C-B Full Rear Module (R2C-8259) is required.
Installing a Rear Module
If the Rear Module is already installed, proceed to the section “Installing the 9275”.
Use the following procedure to install the rear module in an 8300 series frame:
1. Locate the card frame slots on the rear of the frame.
2. Remove the Blank Plate from the slot you have chosen for the 9275 installation.
3. Install the bottom of the Rear Module in the Module Seating Slot at the base of the
frame’s back plane. (Figure 2.1)

Operation Notes
This section provides brief notes when operating the 9275.
Audio Proc Amp Controls
The 9275 includes Processing Amplifiers (Proc Amps) for the audio inputs on the card. Note that
these features are not available when using the card-edge controls.
Proc Amp adjustments are applied in the following order:
1. Delay — This option enables you to adjust the delay of the audio channel. If you have
enabled the Delay Lock feature, changing the delay value for one channel automatically
changes the value for the other channel.
2. Gain — This option provides a +/- 20dB gain range in 1dB increments. If you have
enabled the Gain Lock feature, changing the gain value for one channel automatically
changes the value for the other channel. When using the 9275-C, the gain range is +/10dB.
3. Invert — This option enables you to invert the polarity of the audio signal for the
selected channel.
Minimum Delay Overview
The line buffer stores incoming video in relation to the incoming video clock timing. The video
data is then read out in relation to the reference timing. This allows the input video to be switched
between sources that may not be perfectly timed without timing glitches. Video source timing must
remain within the buffer window to properly switch between sources. Table 3.3 provides
information on the buffer window available depending on how the Minimum Delay feature is
configured in DashBoard.

Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your 9275,
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 Inc. 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-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.
Bootload Button
In the unlikely event of a complete card failure, you may be instructed by a Cobalt Digital Inc.
Technical Support specialist to perform a complete software reload on the 9275.
Use the following procedure to perform a software reload on the 9275:
1. Eject the card
2. Press and hold the Bootload button, while re-inserting the card into the frame.
3. Release the button.
The PWR LED will flash GREEN while the card is waiting for a new software load.
If a new software load is not sent to the card within 60 seconds, the card will attempt to
restart with the last operational software load.
Software can be uploaded to the 9275 via DashBoard. Refer to your DashBoard Control System
Software User Manual for further instructions.
