System Restart

Switch Versions and Restart

What to do next

When the user initiates a switch version, system restart, or system shutdown from the Cisco Unified OS Administration web interface, the operation fails in the following scenarios:

  • If the system detects that a switch version is in progress.

  • If the system detects that a previous switch version was abruptly terminated.


Note

A switch version operation is abruptly terminated if a power reset or hard reboot is done on the Unified CCX system when it is in progress.
