Chapter 1: Technical Overview
Redundancy
Automatic Takeover
If the main Router Module fails, then the redundant module automatically takes over. This ensures a seamless
recovery without any interruption to operation.
Note that a brief interruption to audio will occur while routes are reconfigured.
The redundant control system is automatically activated if, internally, a loss of connection is noticed by the
redundant system. This could be due to a software failure, hardware error or reboot of the main control system.
If the Ethernet connection between the control surface and Router Module fails, then an automatic takeover does
not occur, as the failure could be deliberate (for example, if you disconnect the cable).
Instead the operator is presented with an error message:
1. Click on the message and a confirmation pop-up appears:
2. Select Yes to switch to the redundant control system or No to cancel.
Selecting Yes causes an interruption to the audio.
If you select No , then you MUST fix the problem with the connection before you will regain control of the audio.
