10.4 Video Crosspoint Failure
If Video Redundancy is enabled (see section 10.6) and 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 (see section
10.7 for details on changing this setting):
•
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.
10.4.1 Replacing a Failed Video Crosspoint Module using the Door PC
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.
Sirius 830
- see Figure 35 on page 64 for button and parameter locations.
Sirius 840/850
- see Figure 36 on page 65 for button and parameter locations.
A typical example of how the buttons will look is listed below.:
•
Fail Found indicator
- Red
•
Fault Present indicator
- Red
•
First Failure Detected
-
Failed Source
and
Destinations
will display the first
failed route
•
XpntCardNone
- Grey
•
Sirius 830
•
XpntCardMain830
Yellow (indicates the crosspoint has failed)
•
Sirius 840/850
•
XpntCardxxxToxxx_x
- Yellow (where xxx is the failed crosspoint module)
Note:
•
Any failure needs addressing immediately to retain protection.
•
For information on replacing the failed crosspoint card see section 10.4.1.
•
Following a change in source for a given output (routing change) it can take several
seconds to check the Sirius 800 redundancy. It is assumed that it is okay until this
is done and so no alarm is flagged during this checking period.
Note:
•
The fan assembly should be placed back into the closed position as soon as
possible after opening, as this ensures correct ventilation of the frame. Failure to
do this will result in failure.
•
In practice the maximum time that a fan assembly can be left open will depend on a
number of factors such as; ambient temperature, frame loading, crosspoint
routings, etc. To ensure correct operation under all conditions the fan assemblies
should be left open for no more than 4 minutes at a time.
•
Take care not to trap any cables when opening and closing the fan door.
