Stack Depth

A maximum of eight nodes are supported in the active topology. The slot number configuration assigns only numbers from one to eight.

The stack tolerates an accidental connection of up to 17 nodes. Because only eight nodes can join an active topology, there should never be an accidental connection of two stacks resulting in more than 16 nodes. If you have more than 17 nodes in a stack topology, all nodes enter an overflow state and all stacking links enter a link overflow state. While in an overflow state, the active topology does not function. All slots containing active nodes show a Failed state. The overflow state is maintained until the overflow is cleared by manually disconnecting a sufficient number of nodes. After the overflow is cleared, all nodes in the stack topology reboot.
