MVIEW / WEB INTERFACE REDUNDANCY
34 1TGC908004
6.4. MView / Web Interface
In a dual redundant configuration, the MView
is connected via the same Ethernet net-
work to both Primary and Backup Digital Gateway
.
If a changeover takes place, the current Primary will become the Backup (if still functioning) and
the Backup will become Primary Digital Gateway.
The MView
is automatically redirected to the new Primary Digital Gateway (which was the
Backup 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 Digital Gateway. Once it has re-directed to the new Primary 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 figure above).
