Cascading Switches
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.
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.
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.
1. You may only have multiple cascades between switches in Zone 1.
