Running a back-up Encode Server
A back-up Encode Server runs in parallel with the main Encode Server, as shown by this
diagram:
The feed is connected as a source on the router. Using a tee connection, the main and back-up
Encode Servers are set up as router destinations. The router connects the feed to the main and
back-up Encode Servers.
If you do not use a tee connection between the main and back-up Encode Servers, the servers
must be connected to the same feed using two separate connections.
In either arrangement, each server creates a file in the Media Store. If the main file fails during
playout, iTX will play the back-up file.
Set up a back-up Encode Server
1. On the back-up Encode Server machine, run the iTX installer to install the Encode Server
module.
Follow the same procedure that you follow when installing the module on the main Encode
Server. More details , page 61.
When the iTX Encoder Config dialog appears, ensure you correctly identify the recording
channel:
•
In the Channel Name box, enter the same name as that of the main recording channel
but add the suffix "-BACKUP" (in capital letters). There must be no space between the
recording channel name and the suffix. For example, if the recording channel is
"ENCODER1", call the back-up channel "ENCODER1-BACKUP".

For information on adding a Output Server 2 simulcast channel to an iTX system, see the
Output Server 2 Channel Configuration Guide.
