For example:
•
If Audio Output 1 on the main crosspoint fails:
The output module that Audio Output 1 is routed to selects the redundant crosspoint
audio transport stream.
•
If Audio Output 2 on the main crosspoint fails:
The output module that Audio Output 2 is routed to selects the redundant crosspoint
audio transport stream.
10.5.5 Replacing a Failed Audio Crosspoint Module
A failed audio crosspoint module can be replaced by either using the Door PC to move the
routes from the failed module to the working module or without using the Door screen. Both
methods are described in this section.
•
Replacing an audio crosspoint module using the Door PC, see section 10.5.5.1.
or
•
Replacing an audio crosspoint module without using the Door PC, see section
10.5.5.2.
10.5.5.1
Replacing an Audio Crosspoint Module using the Door PC
If one or more routes fail on an audio crosspoint module this will be displayed on the Audio
Crosspoint Matrix Status screen. A typical example of how the buttons will look is listed below
(see Figure 37 on page 69 for button and parameter locations):
•
Fail Found indicator
- Red
•
Fault Present indicator
- Red
•
First Failure Detected
-
Failed Incoming Stream
and/or
Failed Outgoing
Stream
will display the first failed stream(s)
•
XpntCardNone
- Grey
•
XpntCardRedundant
: Grey
•
XpntCardMain
: Yellow (indicates the main audio crosspoint has failed)
1.
Touch the
Free Failed Crosspoint
button to move all of the routes from the failed
audio crosspoint module to the other audio crosspoint module.
2.
Open the router door and then open the fan door to locate the audio crosspoint
modules.
Note:
•
Any failure needs addressing immediately to retain protection.
•
For information on replacing the failed crosspoint card see section 10.5.5 below.
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.
