What action should be taken before bringing the secondary network online?

Bringing the secondary network online necessitates that the primary network is functioning properly to ensure seamless data transmission and communication between devices. If the primary network is not operational or has issues, adding a secondary network could create complications, such as network conflicts, data loss, or synchronization problems. Therefore, confirming the stability and proper operation of the primary network is essential to avoid complications and ensure a robust and reliable audio network setup.

Other actions, like checking power supplies, reviewing network settings, or updating firmware, are certainly important in their own right but do not address the critical need for the primary network's functionality before adding additional networks. Ensuring the primary network is operational lays a solid foundation for the effective integration of the secondary network.
