Redundancy Operation
chronizing themselves. System redundancy is still functional under these
conditions.
If a “no sync” state persists, the Panel Network configurations should be
checked to make sure that all the panels have correct values for Primary
and Secondary Panel Server IP addresses. Panel communications to both
servers is easily verified by looking at the Panel Description Web page at
the current primary server status and current secondary server status. Both
should report “Server Comm OK.”
If there is a “No Mirror” indication, then the opposite controller is offline or
not working properly and should be checked.
One way to verify proper fail-over behavior is to take the Panel Server
offline using the OUI. The other controller should assume control and
allow normal switching to continue.
SCB Frame Count Server
Encore 1.7.3 and newer software includes a frame count server. This elimi-
nates the need to connect common VITC to redundant SCBs for synchro-
nized Takes.
Note
Automation clients require VITC to perform timed Takes.
The Frame Count Server feature works by having one SCB broadcast a ref-
erence count, and all other SCBs synchronize to it. Since all the SCBs use a
common reference count, they can be configured and operated as redun-
dant pairs without VITC. In case of failure of the server SCB, another SCB
takes over broadcasting the reference count.
If VITC is provided to a system running with the Frame Count Server
enabled, the Frame Count Server and client software within the SCBs auto-
matically go to sleep and use VITC for synchronizing Take operations.
To operate an Encore system with Router Controller and Control Panel
Server redundancy without VITC embedded in the reference signal, follow
the steps below.
1.
Go to the web page of Encore SCB (you can use NetConfig). Go to the
Date, Time, and Frame Count Configuration
. Enable the
Frame Count Server
.
Repeat this step for each of the SCBs in the network.
