MVIEW / W EB INTER FACE REDU NDANCY
30 1TG C908004M0 201
6.4. MView / Web Interface
In a dual redundant configuration the MView is connected via the same Ethernet network
to both Primary and Backup MNS Digital Gateway
.
If a changeover takes place, the current Primary will become the Backup (if still functioning) and
the Backup will become Primary MNS Digital Gateway.
The MView is automatically redirected to the new Primary MNS Digital Gateway (which was the
Backup MNS Digital Gateway before) without user interaction.
While redirecting, the MView shows the following window: Prior to the re-direction the
background in MView changes to yellow to indicate that current Web Interface is connected
to the Backup MNS Digital Gateway. Once it has re-directed to the new Primary MNS Digital
Gateway the background returns to its usual color.
Below screenshots are showing such a change-over scenario:

Note: If a change-over fails or in case any other redundancy error occurs that will be indi-
cated by red square in MView (see Fig26 above).
