Cascading Switches

Note: The primary switch disables the transceivers on all redundant connections, so only the primary cascade is enabled. If the primary cascade goes down, another cascade is then enabled.

Cascading allows you to connect two or more switches together to increase the number of ports and available devices. The switch allows you to link up to 12 switches. Multiple cascades between switches provide link and communication redundancy. You may have up to three cascades between a pair of switches.

The primary cascade is determined by the order of discovery in the primary switch (the switch with the lower Serial Number). If the primary cascade fails in either switch, an automatic failover occurs on one of the other cascades.

Cascading with Non-Overlapping Zones

There are certain cascade restrictions when using non-overlapping zones. The following examples outline these restrictions.
