Synchronizing CPU
CAUTION! MODULE REMOVAL AND INSERTION – ON A POWERED-UP SYSTEM, WAIT AT LEAST 15 SECONDS AFTER ANY MODULE REMOVAL OR INSERTION TO ALLOW THE SYSTEM TO STABILIZE. FAILURE TO FOLLOW THIS PROCEDURE MAY RESULT IN SYSTEM ERRORS REQUIRING TOTAL SYSTEM REBOOT. WHEN INSTALLING A REPLACEMENT CPU IN A REDUNDANT CPU SYSTEM, DO NOT REBOOT OR POWER DOWN THE SYSTEM BEFORE CPU SYNCHRONIZATION IS COMPLETE AS INDICATED BY A SOLID STATUS LIGHT.
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.
