Default port numbers
Each server component has a unique default port assigned to it. This default port may only be used with that type of server. However, application engineers may choose ports other than the defaults, depending on the design of the project. Non-default ports need to also be added to the firewall exceptions.
Which ports are required for a specific installation depends on the Power Monitoring Expert system configuration and the monitoring devices used.
If Power Operation alarm, trend, report and I/O servers are created using non-default ports, create those ports exceptions.
