Installation & Operation Manual 28. Working with the Media Gateway Boards (TP-6310 and TP-8410)
28.5 The Redundancy Model
Media Gateway boards are grouped into Redundancy Groups. Each redundancy
group has a dedicated redundant board (equipped with a redundant RTM module) that
provides hot redundancy protection for the active boards within the group.
By default, a single Redundancy Group is created and all Media Gateway boards are
assigned to it.
28.5.1 Configuring Redundant Media Gateway Board
The redundant board is typically pre-defined on a Media Gateway shipped to
customers. However, you may start working with a Media Gateway without
redundancy, and then add a redundant board later in the process. In this case, use the
Add Board action (as described in 'Media Gateway Board Actions' on page 247) to
add a new board and then follow the procedure described below. Ensure that your
redundant board is equipped with the redundant RTM module.
Use the procedure below to configure the Redundant board under the following
circumstances:
After adding a new Redundant board
After changing the configuration of the active boards (to ensure the availability of
the best possible Redundancy Mode for all boards)
To configure the Redundant Media Gateway board:
1. Click the
button to access the Media Gateway status screen.
2. Select a Media Gateway board to be configured as the Redundant board (note
that redundant board must be equipped with the redundant RTM module).
3. Right-Click the selected Media Gateway board and, from the popup menu, select
Maintenance> Make Board Redundant; the Board Redundancy dialog box is
displayed.
4. From the Select Board drop-down list, select the regular board from which the
configuration is to be copied. For more information, see Section 'Actual
Redundancy Mode' on page 252.
Complete the configuration of the Redundant Board by provisioning its IP addresses
via the Network Settings screen.
Finally, perform the Unlock action on the Redundant board to bring it into service.
Wait for a few minutes till the action completes (the board is restarted as part of this
process; when the process completes, the board's Operational State is changed to
Enabled). Open the Boards Redundancy screen (as described in 'Actual Redundancy
Mode' on page 252) and verify redundancy modes for each regular Media Gateway
board.
