Redundant System
When an ASC970 System includes both a Main CPU and a Backup CPU, it is called a Redundant System. In this
case, one of the WV-ASC970 Server will be running in the Active mode and will actually be controlling the system
operation. The other WV-ASC970 Server will be running in Standby mode and will be following all the system activi-
ty in order to take over system operation, in case the Active CPU fails or otherwise can no longer operate.
The WV-ASC970 Admin Console allows an administrator to set and switch the status of the WV-ASC970 Servers on
the CPU Unit screen.
