Before you install or upgrade BlackBerry UEM, you should familiarize yourself with how UEM uses ports.

The UEM components use various ports to communicate with the BlackBerry Infrastructure, the BlackBerry Dynamics NOC, and internal resources (for example, your organization's messaging software). The topics in this section indicate the default ports that UEM uses for outbound connections and also describe the internal connections that you should verify. These port connections are required whether or not UEM is installed in a DMZ.

The BlackBerry Enterprise Mobility Server (BEMS) must be installed in UEM environments that use BlackBerry Dynamics. BEMS has port requirements for communication with UEM and the BlackBerry Dynamics NOC.

For more information about UEM and BEMS ports, see KB 36470.
