Security configuration

The operating system security options enable you to manage security certificates and Secure Internet Protocol (IPsec). From the Security menu, you can choose the following security options:

  • Certificate Management - Manages certificates and Certificate Signing Requests (CSR). You can display, upload, download, delete, and regenerate certificates. Through Certificate Management, you can also monitor the expiration dates of the certificates on the node.

Software upgrades

The software upgrade options enable you to upgrade the software version that is running on the operating system or to install specific software options, including Cisco Unified Communications Operating System Locale Installers, dial plans, and TFTP server files.

From the Install/Upgrade menu option, you can upgrade system software from either a local disc or a remote server. The upgraded software gets installed on the inactive partition, and you can then restart the system and switch partitions, so the system starts running on the newer software version. See the Upgrade Guide for the Cisco Unified Communications Manager for more information.


You must do all software installations and upgrades by using the software upgrades features that are included in the Cisco Unified Communications Operating System GUI and command line interface. The system can upload and process only software that Cisco Systems approved. You cannot install or use third-party or Windows-based software applications that you may have been using with a previous version of Cisco Unified Communications Manager.


The application provides the following operating system utilities:

  • Ping - Checks connectivity with other network devices.
  • Remote Support - Sets up an account that Cisco support personnel can use to access the system. This account automatically expires after the number of days that you specify.
