CPU data sync occurs automatically and should not require user intervention (see
“CPU Sync” on page

8-17

). If there is a CPU sync problem, follow the steps below

to synchronize data and operating software (SW) between the two CPUs. This
should only be done when there is file manipulation unknown to the system, such
as FTP of new files to the online CPU.

Three options are available for synchronizing CPU: Sync CPU Data Only,
Sync Operating SW, and Sync CPU Data and SW. Synchronizing the
operating software is very time-consuming and should only be done as a last resort
when the standby CPU has no Ethernet connection to update the software by FTP.
