Reconnecting the Original Master Unit After Failover
After failover, if the original master is connected again, the master selection
process is performed. If the original master (unit 1) is reselected to be the master,
the current master (unit 2, which was the original backup unit) is rebooted and
becomes the backup once again.
During master/backup failover, the up time of the backup unit is retained.
All the units in the stack must run the same software version (firmware and
bootcode). Each unit in a stack automatically downloads firmware and bootcode
from the master unit if the firmware and/or boot code that the unit and the master
are running is different. The unit automatically reboots itself to run the new version.
This section describes how to configure a standalone device, a stack, and devices
in the stack. For additional information regarding stack-related hardware options,
see the Quick Start Guide.
