Introduction to the BayStack 410-24T Switch

Stack Operation

BayStack 410-24T switches provide fail-safe stackability when you install (optional) BayStack 400-ST1 Cascade Modules.

The BayStack 400-ST1 Cascade Module supports the following switches1:

Nortel Networks Business Policy Switch 2000

BayStack 450 Switch

BayStack 410-24T Switch

You can create a mixed stack of supported switches, but certain restrictions apply:

As shown in Figure 1-10, in a mixed stack configuration, the BayStack 450 and 410-24T switches must use compatible but device-specific software versions to operate with the Business Policy Switch.
