After the completion of deployment, the two devices will immediately start synchronizing the system
settings. If the process is interrupted by certain reason, then the Backup device has to be removed
from the deployment. After that, reset it to factory default and format its hard disk. Next, repeat the
steps to complete the synchronization. The synchronizing status is available under High Availability
Æ Setting .
To avoid synchronizing error, please make sure the Master device functions properly, which means the
machine is functioning and the management interface is accessible, before turning on the Backup
device.
The device build-in hard disk is replaceable. However the replacement must be equal to or larger than
500 GB or else anomalous data losing may occur as a result.
