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 operation. The Firmware Synchronization configuration parameters are 
global and cannot be changed for each individual stack unit.

If the stack member code is mismatched 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 
progress. In case of firmware corruption during Firmware Synchronization, manual 
intervention by the operator is required to bring the switch back to working condition.

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, 
multiple links can be connected to an adjacent unit to form a higher bandwidth stacking 
connection. This is referred to as Multiple Stack Links.

The following restrictions and limitations apply when using Multiple Stack Links:

Fiber link takes precedence over the copper link

When fiber link is present between the stacked units, traffic is always carried through the 
fiber link, whether over a single link or over two links in a trunk. 

This happens irrespective of one or two copper links present 

Copper link, in the presence of fiber link, always acts as standby and does not 
participate in carrying traffic. However, when the fiber links are down/removed, the
