Install the license file on the Communication Manager main server. Survivable servers do not require a license file.

The license file on the Communication Manager main server controls licensing for survivable servers. The Maximum Survivable Processors (VALUE_CM_SP) feature in the license file specifies the number of survivable servers you can administer on the Communication Manager main server. This number comes from the number of maximum Enterprise Survivable Server (ESS) stations (VALUE_CM_ESS_STA) and maximum Local Survivable Server (LSP) stations (VALUE_CM_LSP_STA) activated in the license file. Each survivable server administered on the main server consumes one of the Maximum Survivable Processors feature capacities.
