The stackable switches may be connected in a daisy-chain topology. This is a ring topology with one of the links disconnected, inoperative, or disabled. A daisy chain can be created when a link fails or a node reboots in a ring topology, but the daisy chain topology is not recommended for normal operation. In the following figure, the nodes delineated as the active topology are operating in a daisy-chain configuration, even though there is physically a ring connection in the stack.
Note
The daisy chain topology is not recommended for normal operation.
You might need to use a daisy chain topology while adding a new node, removing a node, or while joining two stacks.
If you are using a daisy chain topology, the possibility of a dual master situation increases. So before you create a daisy chain topology, read Managing a Dual Master Situation.
Note
The maximum cable length supported between switches depends on the types of Summit family switches in your stack, the installed option cards, and the configured stack ports. For more information, see the Summit Family Switches Hardware Installation Guide.
