GS752TXS Smart Switch Hardware Installation Guide
A stack unit can operate in one of the following Modes:
• Standalone unit runs as a general switch. The standalone unit does not run the stacking
application until it is connected to a stack.
• The Master unit manages the entire stack, and is responsible for the entire stack
configuration. All protocols run in the context of the Master unit. It updates and
synchronizes the Backup master.
• A master-backup unit runs as a slave unit as described above, and in addition, it
continuously monitors the existence and operation of the stack master. If the master unit
fails, the master-backup unit will assume the stack-master role. (“Switchover”).
• A slave unit only runs a slave version of the Distributed Switching Algorithm, which allows
the applications running on the Master unit’s CPU to control and manage the resources of
the slave unit.
