S3300 Smart Managed Pro Switch 
The behavior of Firmware Synchronization is the same whether the system is powered on 
after connecting all the new members or if a new member is adding during the running 
operation of the stack. Stack Firmware Synchronization starts only after the stack manager 
selection is complete.
You can disable downgrading the image on a stack member during Firmware 
Synchronization op
eration. The Firmware Synchronization configuration parameters are 
global and cannot be changed for each individual stack unit.
If the stack member code is mismat
ched stack, then the backup image of the stack member 
is used for Firmware Synchronization.
The reboot operation is allowed, even though there is a synchronization operation in

Multiple Stack Links
The S3300 platforms contain two dedicated (non-combo) 10GBaseT copper links (ports) and 
2 dedicated SFP+ fiber links. Any of these links can be configured for normal Ethernet 
operation or stacking operation. When these links are configured for stacking operation,
