Carrier Access 1750 Manual De Usuario

CPU redundancy is automatically activated when a second CPU is detected in the 
system. If two CPUs are detected at initial boot, the first to boot becomes “online” and 
the other goes into the standby mode. 

CPU redundancy allows the standby CPU to take control if the online CPU experiences 
a failure. Data files on the two CPUs are synchronized automatically when the standby 
CPU is powered up. This synchronization process occurs automatically when the 
standby CPU is powered up. Once both CPUs are functioning (one online and the other 
in standby) any subsequent changes to the system are mirrored (recorded in the online 
CPU and sent to the standby CPU). This process keeps the standby CPU up to date.
