Applies to: RedNet PCIeNX and RedNet TNX

RedNet PCIeNX or TNX is in Redundant mode but I can't select it as the Secondary Network interface in Dante Controller or RedNet Control

The PCIeNX is only a single NIC (Network Interface Card) which means it can only appear as one network port for the Dante network. The redundant mode still functions as expected if you don't select a Secondary Network. However, if any device in your network drops from the Primary network the dropped device won't appear in Dante Controller, but should it still pass audio over the Redundant/Secondary network if setup correctly. 

To add a secondary network interface, the redundant network needs to connect to another network port on your computer either directly or via an adapter. 

RedNet PCIeNX or TNX is in Redundant mode, but only appears as one Network port on my computer

This is normal as the PCIeNX is only a single NIC (Network Interface Card) which means it can only appear as one network port on a computer

RedNet PCIeNX or TNX won't change from Switched mode into Redundant mode when I press reboot in Dante Controller

The PCIeNX must be power cycled (turned off/on) for the reboot to happen:

• If the PCIeNX is in your computer, restart the computer.
• If the PCIeNX is in a Thunderbolt chassis, power cycle the Thunderbolt chassis.

Setting up a Redundant/Secondary Network with the RedNet PCIeNX card or TNX

The RedNet PCIeNX features an inbuilt NIC (Network Interface Card) and two Dante Ports. You can use the Dante ports in switched mode or for Dante Redundancy. 

The PCIeNX NIC port appears as your computer's Network port for connection to the Dante network.

• On Windows, this appears in the Windows Network Connections (Control Panel > Network and Internet > Network Connections). 
• On Mac this appears in Network (System Settings > Network) 

The NIC on the PCIeNX is the port that should be selected as Dante Controller and RedNet Controls Primary Network Interface on the computer the card is connected to/installed in. 
Dante Controller > File > Interfaces
Mac: RedNet Control > Preferences  
Windows: RedNet Control > File > Preferences  

The NIC on the PCIeNX is not the IP address of the Dante port for the card but it is in the same IP address range as the Primary port on the PCIeNX. 

You can use the PCIeNX in redundant mode over the NIC, however, you can not select the PCIeNX port as the Primary and Secondary Dante network port on your computer. To select a Secondary Network interface on your PC, connect an ethernet cable from the Redundant network to another ethernet port on the computer, either directly or via an ethernet adapter. You can then select it as the Secondary Network interface in Dante Controller.

In the below example, the PCIeNX is set up in redundant mode along with a RedNet D16R MkII. 
The NIC on the PCIeNX the Primary Network interface and the two IP addresses for the PCIeNX primary and secondary/redundant networks are self-assigned. 

RedNet PCIeNX IP Addresses

NIC (Ethernet2) = 192.168.2.16

Primary Dante Address = 192.168.2.38

Secondary Address = 172.31.204.198

To select a Secondary Interface for the redundant network I need to route my redundant network to another connection on the PC:

Now there is a separate PC connection to the secondary network I can select this as the Secondary Network interface in Dante Controller:

The Secondary interface in Dante Controller does not pass audio, and all audio still passes through the PCIeNX even using the redundant/secondary port. Having a Secondary Interface selected in Dante Controller and RedNet Control 2 allows Dante Controller and RedNet Control 2 to see the redundant network and allows both pieces of software to have control over units on the Secondary network in cases where the Primary network fails or drops out.
