If everything related to the PRA-APAS is working correctly, check the Ethernet managed
switch/router for its configuration of VLAN, routing, NAT, etc.
If you are still unable to connect to the device with the browser, refer to Unable to connect to
the device after misconfiguring network settings, page 36.
10.4 Unable to prelisten on Apple PC using Safari
1. Check that PRA-APAS website is listed in Safari > Preferences > Websites > Auto-Play .
2. Select Allow All Auto-Play .
10.5 Unable to hear anything in any area
– Verify that the AES67 channels are properly routed to the PRAESENSA inputs.
–
Check, for example, the Figure in
Dante controller setup, page 17.
– Make sure that no other device is using the following multicast addresses:
–
239.69.2.11;
– 239.69.2.12.
– Verify in the Dante controller that the device/AES67 Config/RTP Multicast Address Prefix
is configured to 69 (239.69.xxx.xxx).
You can also try to remove the routing and add it again, or:
1.
Route the inputs to the outputs of the PRAESENSA.
2. Route them back to PRA-APAS channels.
10.6 The device has no Internet connection
– Check if the Ethernet cable is connected to the network interface.
– Try to power off and on the PRA-APAS device.
– Check if the remote server is visible from a different computer on the same network, and
try to ping it.
– Check the Ethernet managed switch/router for its configuration of VLAN, routing, NAT,
etc.
If none of the previous steps solve the problem:
1.
Select the Settings tile in administrator module.
– Check the semaphore status of the ETH2 network interface if you are using the
corporate network.
– Check the semaphore status of the ETH1 network interface if you are using the
private network.
If the semaphore status is red, the root cause of the problem is a faulty network connection.
–
Check if an Ethernet cable in the network interface is disconnected.
– Check if the network settings for the corporate network are misconfigured.
– Check if a cable on the other side of the network switch is disconnected.
If the semaphore status is green, the Ethernet cable is well connected and the Ethernet
connection between both sides is working correctly. In that case:
1.
Check if you have set your DHCP/static network settings correctly.
2. Try to restart the network in the Settings tile in administrator module.
