There are three versions of the BayStack 450 switch: the Model 450-24T, the
Model 450-12T, and the Model 450-12F. This guide describes the features, uses,
and installation procedures for the three versions. (Unless otherwise specified, the
terms "BayStack 450 switch" and "switch" refer to all switch versions.)
BayStack 450 switches include a dedicated Uplink/Expansion Module slot for
attaching optional media dependent adapters (MDAs) that support a range of
media types, including gigabit Ethernet and asynchronous transfer mode (ATM).
Installation instructions are included with each MDA (see your Nortel Networks
sales representative for ordering information).
For more information about the MDAs, see Appendix C, "Media Dependent
Adapters."
BayStack 450 switches provide Fail-Safe stackability when you install the
optional BayStack 400-ST1 Cascade Module. Installation instructions are
included with each BayStack 400-ST1 Cascade Module (see your Nortel
Networks sales representative for ordering information).
For more information about the BayStack 400-ST1 Cascade Module, see "Stack
