5.4.1.1 Video Crosspoint Failure
When a video crosspoint routing failure is detected by the redundant crosspoint checking
algorithm the Nucleus router controller performs one of the following actions based on the
configuration in Workbench:
• Move the failed route to the redundant crosspoint (default when shipped).
• Move all routes from the crosspoint module with the failure to the redundant
crosspoint module
• Just notify the user and leave them to take appropriate action.
If one or more routes fail on a video crosspoint module this will be displayed on the Main or
Expansion Video Crosspoint Matrix Status screen. A typical example of how the buttons will
look is listed below (see Figure 35 on page 64 or Figure 36 on page 65 for button and
parameter locations):
• Fail Found indicator - Red
• Fault Present indicator - Red
• First Failure Detected - Failed Source and Destinations will display the first
failed route
• XpntCardNone - Grey
• Failed Action: - text as configured in Workbench
• Sirius 830
• XpntCardMain830 Yellow (indicates the crosspoint has failed)
• Sirius 840/850
• XpntCardxxxToxxx_x - Yellow (where xxx is the failed crosspoint module)
• See section 10.6 for details on enabling/disabling video redundancy and section
10.7 for details on setting the redundancy action on crosspoint failure.
• For information on replacing a failed crosspoint module see section 10.4.1.
