In a ring connected stack, it can still operate normally by transforming into a daisy
chained stack when link failure occurs, which further ensures the normal operation of
load distribution and backup across devices and links as Figure 5-2 shows.
3. Network scalability. Each member device in the stack system is able to process protocol
packets and forward data individually, which enables you to increase the port number and
bandwidth of the stack system by adding new member devices. The users are free to add
or remove stack members without affecting the normal running of the stack, which enables
them to protect the existed resources furthest during network upgrades.
