/mcpFrom the Settings > Version window, you can select from the following options for restarting or shutting down the system: • Switch Versions—Switches the active and inactive disk partitions and restarts the system. You normally select this option after the inactive partition has been updated and you want to start running a newer software version. • Current Version—Restarts the system without switching partitions. • Shutdown System—Stops all running software and shuts down the server. This command does not power down the server. To power down the server, press the power button. Note For more information see Chapter “Version Settings”. Security Configuration The operating system security options enable you to manage security certificates and Secure Internet Protocol (IPSec). From the Security menu, you can select the following security options: • Certificate Management—Manages certificates, Certificate Trust Lists (CTL), 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 server. • IPSEC Management—Displays or updates existing IPSEC policies; sets up new IPSEC policies and associations. For more information, see Chapter “Security”. 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. You must do all software installations and upgrades with 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.
