Fail-safe stack applicationFigure 11 shows an example of eight Business Policy 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 11, the Passport 1100 switch is used as a backbone switch,
connecting to the Business Policy 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 Business
Policy Switches, see “Business Policy Switch stack operation.”
