Stack Firmware Synchronization
The Firmware Synchronization feature provides an automatic mechanism to synchronize the 
firmware on stack members whose firmware version is different from the version running on 
the stack manager. Subject to configuration, this synchronization operation may result in 
either an upgrade or a downgrade of firmware on the mismatched stack member. The feature 
also checks for boot code version compatibility before starting the upgrade.
By default, the Firmware Synchronization feature is disabled. 
Activating the firmware image is not possible if
 the minimum boot code specified in the image 
file is not met by the running boot code on the switch and the auto boot code upgrade feature 
is not present.
