1) Fitting an MV-831 into a Sirius 830 Router
Router Power Supplies: Sirius 830 routers have powerful power supplies. In most cases, these are sufficient for powering
MV-831(s). Grass Valley recommends checking your router power supply configuration with Grass Valley support before
fitting MV-831(s) into the router. (For contact details, see https:/www.grassvalley.com/contact/support/)
MV-831: This is a double-width Sirius 830 module, comprising double-width Rear & Front modules. See Figure 1.
Fitting instructions:
1. If SFP modules are supplied separately, fit them to the MV-830-RP rear module.
An MV-831 module occupies a pair of (front and rear) router input/output slots. For example: slot-pairs 1 & 2; or 11 & 12.
Note: Router I/O slot numbering: From the front, numbering is left-to-right; from the rear, numbering is right-to-left:
2. Ensure a vertical ‘slot-pair’of router input/output module slots are available and empty.
Go to the rear of the router:
3. Remove any blanking plate already covering the router rear slots.
4. Fit the MV-830-RP rear module. Secure with four screws.
Go to the front of the router:
5. Open the router front outer door; open the lower router fan door.
6. Insert the MV-831-MB front module. Push the module into the slots
with the module ejector handles.
Ensure the module is pushed fully into the slots with module ejector handles pushed fully inwards.
7. Close the router’s fan door and front outer door.
Caution: Always keep router doors closed to ensure correct unit ventilation and
operation. Only open a router door for a maximum of 2 minutes.
Booting: After the front module is fitted, the MV-831 begins to boot up.
Booting up lasts for approximately 1 to 2 minutes. During boot-up:
8. A splash screen appears on each active multiviewer head display output.
Connect a monitor to each. See Figure 3. IP addresses are shown.
9. After booting, each multiviewer head display output shows a default video
wall. See Figure 5 on page 3.

4) Network Configuration
1. Start Grass Valley RollCall Control Panel (v4.17.1 or later) on a
laptop PC. Click the Build Network icon.
2. Enter the MV-831 Ethernet port 1 (1G1) default IP address,
10.54.31.221.
RollCall Control Panel connects to the MV-831 and the MV-831’s
RollCall Control Screen is shown.
3. Navigate to the System-Setup screen.
4. Set up Network Settings relevant to your house network (IP
address, Subnet mask, etc).
5. In RollCall Settings, set up Unit number (default = 01) and
Domain ID (default = 100) for the MV-831.
Note: Unit number must be unique for each unit.
Typically, ‘Domain ID’ is the same for each unit.
Restart MV-831:
6. In the System-Setup screen:,
click System Reset; then click Confirm.
The MV-831 boots up and a splash screen shows the unit’s IP
address and other details (see Figure 3).
After MV-831 has restarted, initial network configuration is complete.
7. Disconnect MV-831 Ethernet port 1 from laptop PC.
And connect the port to the house network.

5) Router Configuration
Both of the Sirius 830 router slots used by an MV-831 must be set up in the
router’s configuration. See items shown in Table 2.
Multiviewer Monitoring Mode:
By default, all MV-831 router o/ps and i/ps are monitored by the MV-831’s
48-input multiviewer (1 to 48 = O/ps 1 to 24 and I/ps 1 to 24 respectively).
(Monitoring mode is set with router slot configuration items Redundant
Crosspoint Enable and Main Output Follow, both enabled by default.
