Using the BayStack 410-24T 10BASE-T Switch

Fail-Safe Stack Application

Figure 1-9 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 1-9, an Accelar 1100 switch is used as a backbone switch, connecting to a BayStack 450 switch with an optional gigabit 1000BASE-SXMDA 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.
