5.4.2.1 Audio Crosspoint Failure
If an output module detects an error in the audio transport stream from the main audio
crosspoint module or if the stream is not present it will use the transport stream from the
redundant audio crosspoint module (if fitted). The Route Fail LED on the audio crosspoint
module with the failure will flash red, see section 10.5.1 for the location of the status LEDs.
A typical example of how the buttons will look is listed below, for button and parameter
locations see Figure 37 on page 69.
• Fail Found indicator - Red
• Fault Present indicator - Red
• First Fail Detected - Failed Incoming Stream and/or Failed Outgoing Stream
will display the first failed stream(s)
• XpntCardNone - Grey
• XpntCardMain Yellow (indicates the main audio crosspoint has failed)
Crosspoint Status
XpntCardNone Yellow = Main and redundant crosspoint modules working
correctly.
Grey = A fault has occurred or a crosspoint has been by-passed.
XpntCardRedundant
button
Touch the button to bypass the redundant crosspoint card.
Grey = Redundant crosspoint card is working correctly.
Yellow = Redundant crosspoint card has failed or been
bypassed.
XpntCardMain button Touch the button to bypass the main crosspoint card.
Grey = Main crosspoint card is working correctly
Yellow = Main crosspoint card has failed or been bypassed.
Presence Green = Crosspoint module present
Red = Crosspoint module not present
Power Green = Crosspoint module is powered
Red = Crosspoint module is not powered
More button Displays the Modules screen, see section 5.2.2 for details.
Fault Fixed button Switches the routes back to the main crosspoint module once it
has been replaced.
Free Failed Crosspoint
button
Moves all of the routes from the failed crosspoint module to the
redundant crosspoint module. Also makes the redundant
crosspoint module the Clock Master allowing the failed crosspoint
module to be replaced. The “Route Active” LED on the failed
crosspoint module will go off.
The failed crosspoint card can be replaced without interrupting
any crosspoint routing once the routes have been switched to the
redundant crosspoint module, see section 10.5.5.
