Preface
Congratulations on your purchase of the BayStack 450 switch, part of the
Nortel Networks
®
BayStack 10/100/1000 Switch line of communications
products.
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 Module slot for attaching
optional media dependent adapters (MDAs) that support a range of media types,
including gigabit Ethernet. 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 configured with BayStack 450 software version V1.1.0 or
later 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
Operation” on page 1-23.
