Once a certificate is purchased and received it is stored in the Collaboration Server and used for all 
subsequent secured connections. For more information see the Ultra Secure Mode chapter, 

The following System Flags in system.cfg control secure communications.

● RMX_MANAGEMENT_SECURITY_PROTOCOL
● EXTERNAL_DB_PORT 

Table 5-125, below, lists both flags and their settings.

If the System Flag, RMX_MANAGEMENT_SECURITY_PROTOCOL does not exist in the system, it must be 
created by using the Setup menu.

For more information see 

The Collaboration Server must be restarted for modified flag settings to take effect. 

After the SSL/TLS Certificate is installed, secure communications are enabled by modifying the properties 
of the Management Network in the Management Network properties dialog box.

When Secure Communications Mode is enabled:

● Only https:// commands from the browser to the Control Unit IP Address of the Collaboration 

Server are accepted.

● The Collaboration Server listens only on secured port 443. 
● All connection attempts on port 80 are rejected.
● A secure communication indicator () is displayed in the browser’s status bar.
