Fail-Safe Stack Application
Figure 1-8 shows eight switches (a single BayStack 450 switch and seven
BayStack 410-24T switches) that are stacked together as a single managed unit. If
any unit in the stack fails, the remaining stack remains operational.
As shown in Figure 1-8
, an Accelar 1100 switch is used as a backbone switch,
connecting to a BayStack 450 switch with an optional gigabit 1000BASE-SX
MDA for maximum bandwidth (the BayStack 410-24T switch does not support
gigabit MDAs).
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 410-24T switches, see
Stack Operation
following this section.
