Cisco Cisco Process Orchestrator 3.0 Guida All'Installazione

To ensure that load balancing is running successfully, you can either:

-or-

Disable the network interface or bring down the server that the Process Orchestrator is running on. 

In a production environment, you should be monitoring specific NBWS ports (by default 61526 or 
61527), server port (61525), or IIS port (2081) and can test just by bringing down these applications or 
services.
