Note:
Iss 5 Rev 7
3.
Check that the "Route Active" LED on the failed audio crosspoint module is off and
then remove the failed audio crosspoint module (see section 10.5.1 for the location of
the Route Active LED).
4.
Replace the failed audio crosspoint module with a replacement working crosspoint
module and close and secure the fan door and router door.
5.
The replacement audio crosspoint module is automatically tested and the Fault
Present indicator will change back to Green if the replacement is fully working.
6.
Touch the Fault Fixed button to move all of the routes from the redundant crosspoint
module to the replacement audio crosspoint module.
7.
The Audio Crosspoint Matrix Status screen should now return to its working state (see
Figure 37 on page 69 for button and parameter locations):
•
Fail Found indicator - Green
•
Fault Present indicator - Green
•
First Failure Detected - Failed Incoming Stream and Failed Outgoing Stream
will be reset to 0
•

•
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.
1.
Open the router door and then open the fan door to locate the audio crosspoint
modules. Identify the faulty audio crosspoint module, the "Route Fail" LED will be
flashing Red (see section 10.5.1 for the location of the status LEDs).
2.
Press the Reset button on the failed audio crosspoint module (Figure 111 on page
167) so that the working crosspoint module uses its own audio system clock.
CLK Master LED = On for the working audio crosspoint module, see section 10.5.1
for the location of the "CLK Master" LED.
3.
The faulty audio crosspoint module can be hot swapped for a working audio
crosspoint module without causing any disturbance to audio on the router.
4.
Close and secure the fan door and router door.
