Fail-Safe Stack Application
Figure 1-9 shows an example of eight BayStack 450 switches that are stacked
together as a single managed unit. If any single unit in the stack fails, the
remaining stack remains operational, without interruption.
As shown in Figure 1-9
, the Accelar 1100 switch is used as a backbone switch,
connecting to the BayStack 450 switch with an optional gigabit (1000BASE-SX)
MDA for maximum bandwidth. This configuration uses optional BayStack
400-ST1 Cascade Modules to connect the switches in the fail-safe stack.
For an overview of the fail-safe stacking feature that is available for the BayStack
450 switches, see “
Stack Operation” following this section.
