Any other unit member of the stack is named stack slave. In particular, firmware can be downloaded from the stack master to the other units in the stack. A unit serving as Stack Master runs the fully operational software of a switch. In addition, it runs the master part of the Distributed Switching Application that configures and manages all other units in the stack. Generally, the master operates the remote Slave's low-level drivers, thorough the Distributed Switching application part that is running in the context of the Slave. During the Stacking setup, the switches will auto-select one as the Stacking Master. All other devices are named as slave stack members, and assigned a unique Unit ID. One of the slave units is designated as the backup master. The backup master acts as a slave stack master, but can become a Introduction 1-5 v1.0, April 2009
